OSPF
OSPF is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS). It is defined as OSPF Version 2 in RFC 2328 (1998) for IPv4. Updates for IPv6 are specified as OSPF Version 3 in RFC 5340 (2008). OSPF supports the CIDR addressing model.
OSPF is a widely used IGP in large enterprise networks.
OSPFv2 (IPv4)
Configuration
General
VyOS does not have a special command to start the OSPF process. The OSPF process starts when the first ospf enabled interface is configured.
This command specifies the OSPF enabled interface(s). If the interface has an address from defined range then the command enables OSPF on this interface so router can provide network information to the other ospf routers via this interface.
This command is also used to enable the OSPF process. The area number can be specified in decimal notation in the range from 0 to 4294967295. Or it can be specified in dotted decimal notation similar to ip address.
This command sets the reference bandwidth for cost calculations, where bandwidth can be in range from 1 to 4294967, specified in Mbits/s. The default is 100Mbit/s (i.e. a link of bandwidth 100Mbit/s or higher will have a cost of 1. Cost of lower bandwidth links will be scaled with reference to this cost).
This command sets the router-ID of the OSPF process. The router-ID may be an IP address of the router, but need not be – it can be any arbitrary 32bit number. However it MUST be unique within the entire OSPF domain to the OSPF speaker – bad things will happen if multiple OSPF speakers are configured with the same router-ID!
Optional
Originate an AS-External (type-5) LSA describing a default route into all
external-routing capable areas, of the specified metric and metric type.
If the always keyword is given then the default is always
advertised, even when there is no default present in the routing table.
The argument route-map specifies to advertise the default route
if the route map is satisfied.
This command change distance value of OSPF globally. The distance range is 1 to 255.
This command change distance value of OSPF. The arguments are the distance values for external routes, inter-area routes and intra-area routes respectively. The distance range is 1 to 255.
Note
Routes with a distance of 255 are effectively disabled and not installed into the kernel.
This command allows to log changes in adjacency. With the optional
detail argument, all changes in adjacency status are shown.
Without detail, only changes to full or regressions are shown.
This enables RFC 3137 support, where the OSPF process describes its transit links in its router-LSA as having infinite distance so that other routers will avoid calculating transit paths through the router while still being able to reach networks through the router.
This support may be enabled administratively (and indefinitely) with the
administrative command. It may also be enabled conditionally.
Conditional enabling of max-metric router-lsas can be for a period of
seconds after startup with the on-startup <seconds> command
and/or for a period of seconds prior to shutdown with the
on-shutdown <seconds> command. The time range is 5 to 86400.
This command selects ABR model. OSPF router supports four ABR models:
cisco – a router will be considered as ABR if it has several configured links to the networks in different areas one of which is a backbone area. Moreover, the link to the backbone area should be active (working). ibm – identical to “cisco” model but in this case a backbone area link may not be active. standard – router has several active links to different areas. shortcut – identical to “standard” but in this model a router is allowed to use a connected areas topology without involving a backbone area for inter-area connections.
Detailed information about “cisco” and “ibm” models differences can be found in RFC 3509. A “shortcut” model allows ABR to create routes between areas based on the topology of the areas connected to this router but not using a backbone area in case if non-backbone route will be cheaper. For more information about “shortcut” model, see ospf-shortcut-abr-02.txt
RFC 2328, the successor to RFC 1583, suggests according to section G.2 (changes) in section 16.4.1 a change to the path preference algorithm that prevents possible routing loops that were possible in the old version of OSPFv2. More specifically it demands that inter-area paths and intra-area backbone path are now of equal preference but still both preferred to external paths.
This command should NOT be set normally.
This command specifies interface as passive. Passive interface advertises its address, but does not run the OSPF protocol (adjacencies are not formed and hello packets are not generated).
This command specifies all interfaces as passive by default. Because this
command changes the configuration logic to a default passive; therefore,
interfaces where router adjacencies are expected need to be configured
with the passive-interface-exclude command.
This command allows exclude interface from passive state. This command is
used if the command passive-interface default was configured.
The router automatically updates link-state information with its neighbors. Only an obsolete information is updated which age has exceeded a specific threshold. This parameter changes a threshold value, which by default is 1800 seconds (half an hour). The value is applied to the whole OSPF router. The timer range is 10 to 1800.
This command sets the initial delay, the initial-holdtime and the
maximum-holdtime between when SPF is calculated and the event which
triggered the calculation. The times are specified in milliseconds and must
be in the range of 0 to 600000 milliseconds. delay sets the
initial SPF schedule delay in milliseconds. The default value is 200 ms.
initial-holdtime sets the minimum hold time between two
consecutive SPF calculations. The default value is 1000 ms.
max-holdtime sets the maximum wait time between two
consecutive SPF calculations. The default value is 10000 ms.
Area Configuration
This command specifies the area to be a Stub Area. That is, an area where no router originates routes external to OSPF and hence an area where all external routes are via the ABR(s). Hence, ABRs for such an area do not need to pass AS-External LSAs (type-5) or ASBR-Summary LSAs (type-4) into the area. They need only pass Network-Summary (type-3) LSAs into such an area, along with a default-route summary.
This command specifies the area to be a Totally Stub Area. In addition to stub area limitations this area type prevents an ABR from injecting Network-Summary (type-3) LSAs into the specified stub area. Only default summary route is allowed.
This command sets the cost of default-summary LSAs announced to stubby areas. The cost range is 0 to 16777215.
This command specifies the area to be a Not So Stubby Area. External routing information is imported into an NSSA in Type-7 LSAs. Type-7 LSAs are similar to Type-5 AS-external LSAs, except that they can only be flooded into the NSSA. In order to further propagate the NSSA external information, the Type-7 LSA must be translated to a Type-5 AS-external-LSA by the NSSA ABR.
This command specifies the area to be a NSSA Totally Stub Area. ABRs for such an area do not need to pass Network-Summary (type-3) LSAs (except the default summary route), ASBR-Summary LSAs (type-4) and AS-External LSAs (type-5) into the area. But Type-7 LSAs that convert to Type-5 at the NSSA ABR are allowed.
This command sets the default cost of LSAs announced to NSSA areas. The cost range is 0 to 16777215.
Specifies whether this NSSA border router will unconditionally translate Type-7 LSAs into Type-5 LSAs. When role is Always, Type-7 LSAs are translated into Type-5 LSAs regardless of the translator state of other NSSA border routers. When role is Candidate, this router participates in the translator election to determine if it will perform the translations duties. When role is Never, this router will never translate Type-7 LSAs into Type-5 LSAs.
This command specifies that simple password authentication should be used for the given area. The password must also be configured on a per-interface basis.
This command specify that OSPF packets must be authenticated with MD5 HMACs within the given area. Keying material must also be configured on a per-interface basis.
This command summarizes intra area paths from specified area into one
summary-LSA (Type-3) announced to other areas. This command can be used
only in ABR and ONLY router-LSAs (Type-1) and network-LSAs (Type-2)
(i.e. LSAs with scope area) can be summarized. AS-external-LSAs (Type-5)
can’t be summarized - their scope is AS. The optional argument
cost specifies the aggregated link metric. The metric range is 0
to 16777215.
This command instead of summarizing intra area paths filter them - i.e. intra area paths from this range are not advertised into other areas. This command makes sense in ABR only.
One Type-3 summary-LSA with routing info <E.F.G.H/M> is announced into backbone area if defined area contains at least one intra-area network (i.e. described with router-LSA or network-LSA) from range <A.B.C.D/M>. This command makes sense in ABR only.
This parameter allows to “shortcut” routes (non-backbone) for inter-area routes. There are three modes available for routes shortcutting:
default – this area will be used for shortcutting only if ABR does not have a link to the backbone area or this link was lost. enable – the area will be used for shortcutting every time the route that goes through it is cheaper. disable – this area is never used by ABR for routes shortcutting.
Provides a backbone area coherence by virtual link establishment.
In general, OSPF protocol requires a backbone area (area 0) to be coherent and fully connected. I.e. any backbone area router must have a route to any other backbone area router. Moreover, every ABR must have a link to backbone area. However, it is not always possible to have a physical link to a backbone area. In this case between two ABR (one of them has a link to the backbone area) in the area (not stub area) a virtual link is organized.
<number> – area identifier through which a virtual link goes. <A.B.C.D> – ABR router-id with which a virtual link is established. Virtual link must be configured on both routers.
Formally, a virtual link looks like a point-to-point network connecting two ABR from one area one of which physically connected to a backbone area. This pseudo-network is considered to belong to a backbone area.
Interface Configuration
This command sets OSPF authentication key to a simple password. After setting, all OSPF packets are authenticated. Key has length up to 8 chars.
Simple text password authentication is insecure and deprecated in favour of MD5 HMAC authentication.
This command specifys that MD5 HMAC authentication must be used on this interface. It sets OSPF authentication key to a cryptographic password. Key-id identifies secret key used to create the message digest. This ID is part of the protocol and must be consistent across routers on a link. The key can be long up to 16 chars (larger strings will be truncated), and is associated with the given key-id.
This command sets the interface bandwidth for cost calculations, where bandwidth can be in range from 1 to 100000, specified in Mbits/s.
This command sets link cost for the specified interface. The cost value is set to router-LSA’s metric field and used for SPF calculation. The cost range is 1 to 65535.
Set number of seconds for router Dead Interval timer value used for Wait Timer and Inactivity Timer. This value must be the same for all routers attached to a common network. The default value is 40 seconds. The interval range is 1 to 65535.
Set number of seconds for Hello Interval timer value. Setting this value, Hello packet will be sent every timer value seconds on the specified interface. This value must be the same for all routers attached to a common network. The default value is 10 seconds. The interval range is 1 to 65535.
This command disables check of the MTU value in the OSPF DBD packets. Thus, use of this command allows the OSPF adjacency to reach the FULL state even though there is an interface MTU mismatch between two OSPF routers.
This command allows to specify the distribution type for the network connected to this interface:
broadcast – broadcast IP addresses distribution. non-broadcast – address distribution in NBMA networks topology. point-to-multipoint – address distribution in point-to-multipoint networks. point-to-point – address distribution in point-to-point networks.
This command sets Router Priority integer value. The router with the highest priority will be more eligible to become Designated Router. Setting the value to 0, makes the router ineligible to become Designated Router. The default value is 1. The interval range is 0 to 255.
This command sets number of seconds for RxmtInterval timer value. This value is used when retransmitting Database Description and Link State Request packets if acknowledge was not received. The default value is 5 seconds. The interval range is 3 to 65535.
This command sets number of seconds for InfTransDelay value. It allows to set and adjust for each interface the delay interval before starting the synchronizing process of the router’s database with all neighbors. The default value is 1 seconds. The interval range is 3 to 65535.
Manual Neighbor Configuration
OSPF routing devices normally discover their neighbors dynamically by listening to the broadcast or multicast hello packets on the network. Because an NBMA network does not support broadcast (or multicast), the device cannot discover its neighbors dynamically, so you must configure all the neighbors statically.
This command specifies the IP address of the neighboring device.
This command specifies the length of time, in seconds, before the routing device sends hello packets out of the interface before it establishes adjacency with a neighbor. The range is 1 to 65535 seconds. The default value is 60 seconds.
Redistribution Configuration
This command redistributes routing information from the given route source to the OSPF process. There are five modes available for route source: bgp, connected, kernel, rip, static.
This command specifies the default metric value of redistributed routes. The metric range is 0 to 16777214.
This command specifies metric for redistributed routes from the given route source. There are five modes available for route source: bgp, connected, kernel, rip, static. The metric range is 1 to 16777214.
This command specifies metric type for redistributed routes. Difference between two metric types that metric type 1 is a metric which is “commensurable” with inner OSPF links. When calculating a metric to the external destination, the full path metric is calculated as a metric sum path of a router which had advertised this link plus the link metric. Thus, a route with the least summary metric will be selected. If external link is advertised with metric type 2 the path is selected which lies through the router which advertised this link with the least metric despite of the fact that internal path to this router is longer (with more cost). However, if two routers advertised an external link and with metric type 2 the preference is given to the path which lies through the router with a shorter internal path. If two different routers advertised two links to the same external destimation but with different metric type, metric type 1 is preferred. If type of a metric left undefined the router will consider these external links to have a default metric type 2.

The table consists of following data:
OSPF network routing table – includes a list of acquired routes for all accessible networks (or aggregated area ranges) of OSPF system. “IA” flag means that route destination is in the area to which the router is not connected, i.e. it’s an inter-area path. In square brackets a summary metric for all links through which a path lies to this network is specified. “via” prefix defines a router-gateway, i.e. the first router on the way to the destination (next hop). OSPF router routing table – includes a list of acquired routes to all accessible ABRs and ASBRs. OSPF external routing table – includes a list of acquired routes that are external to the OSPF process. “E” flag points to the external link metric type (E1 – metric type 1, E2 – metric type 2). External link metric is printed in the “<metric of the router which advertised the link>/<link metric>” format.
This command displays a table of paths to area boundary and autonomous system boundary routers.

OSPFv3 (IPv6)
Configuration
General
VyOS does not have a special command to start the OSPFv3 process. The OSPFv3 process starts when the first ospf enabled interface is configured.
This command specifies the OSPFv3 enabled interface. This command is also used to enable the OSPF process. The area number can be specified in decimal notation in the range from 0 to 4294967295. Or it can be specified in dotted decimal notation similar to ip address.
This command sets the router-ID of the OSPFv3 process. The router-ID may be an IP address of the router, but need not be – it can be any arbitrary 32bit number. However it MUST be unique within the entire OSPFv3 domain to the OSPFv3 speaker – bad things will happen if multiple OSPFv3 speakers are configured with the same router-ID!
Optional
This command change distance value of OSPFv3 globally. The distance range is 1 to 255.
Area Configuration
This command summarizes intra area paths from specified area into one Type-3 Inter-Area Prefix LSA announced to other areas. This command can be used only in ABR.
Interface Configuration
This command sets link cost for the specified interface. The cost value is set to router-LSA’s metric field and used for SPF calculation. The cost range is 1 to 65535.
Set number of seconds for router Dead Interval timer value used for Wait Timer and Inactivity Timer. This value must be the same for all routers attached to a common network. The default value is 40 seconds. The interval range is 1 to 65535.
Set number of seconds for Hello Interval timer value. Setting this value, Hello packet will be sent every timer value seconds on the specified interface. This value must be the same for all routers attached to a common network. The default value is 10 seconds. The interval range is 1 to 65535.
This command disables check of the MTU value in the OSPF DBD packets. Thus, use of this command allows the OSPF adjacency to reach the FULL state even though there is an interface MTU mismatch between two OSPF routers.
This command allows to specify the distribution type for the network connected to this interface:
broadcast – broadcast IP addresses distribution. point-to-point – address distribution in point-to-point networks.
This command sets Router Priority integer value. The router with the highest priority will be more eligible to become Designated Router. Setting the value to 0, makes the router ineligible to become Designated Router. The default value is 1. The interval range is 0 to 255.
This command specifies interface as passive. Passive interface advertises its address, but does not run the OSPF protocol (adjacencies are not formed and hello packets are not generated).
This command sets number of seconds for RxmtInterval timer value. This value is used when retransmitting Database Description and Link State Request packets if acknowledge was not received. The default value is 5 seconds. The interval range is 3 to 65535.
This command sets number of seconds for InfTransDelay value. It allows to set and adjust for each interface the delay interval before starting the synchronizing process of the router’s database with all neighbors. The default value is 1 seconds. The interval range is 3 to 65535.
Redistribution Configuration
This command redistributes routing information from the given route source to the OSPFv3 process. There are five modes available for route source: bgp, connected, kernel, ripng, static.
Operational Mode Commands
This command displays the neighbors information in a detailed form, not just a summary table.
This command displays the neighbors information in a detailed form for a neighbor whose IP address is specified.
This command displays the neighbors status for a neighbor on the specified interface.
This command displays state and configuration of OSPF the specified
interface, or all interfaces if no interface is given. Whith the argument
prefix this command shows connected prefixes to advertise.
This command displays the OSPF routing table, as determined by the most recent SPF calculation.
This command displays a table of paths to area boundary and autonomous system boundary routers.
This command displays a database contents for a specific link advertisement type.
Configuration Example
A typical configuration using 2 nodes.
Node 1:
set protocols ospfv3 area 0.0.0.0 interface eth1
set protocols ospfv3 area 0.0.0.0 range 2001:db8:1::/64
set protocols ospfv3 parameters router-id 192.168.1.1
set protocols ospfv3 redistribute connected
Node 2:
set protocols ospfv3 area 0.0.0.0 interface eth1
set protocols ospfv3 area 0.0.0.0 range 2001:db8:2::/64
set protocols ospfv3 parameters router-id 192.168.2.1
set protocols ospfv3 redistribute connected
To see the redistributed routes:
show ipv6 ospfv3 redistribute
Note
You cannot easily redistribute IPv6 routes via OSPFv3 on a WireGuard interface link. This requires you to configure link-local addresses manually on the WireGuard interfaces, see T1483.
Example configuration for WireGuard interfaces:
Node 1
set interfaces wireguard wg01 address 'fe80::216:3eff:fe51:fd8c/64'
set interfaces wireguard wg01 address '192.168.0.1/24'
set interfaces wireguard wg01 peer ospf02 allowed-ips '::/0'
set interfaces wireguard wg01 peer ospf02 allowed-ips '0.0.0.0/0'
set interfaces wireguard wg01 peer ospf02 endpoint '10.1.1.101:12345'
