The bonding interface provides a method for aggregating multiple network interfaces into a single logical “bonded” interface, or LAG, or ether-channel, or port-channel. The behavior of the bonded interfaces depends upon the mode; generally speaking, modes provide either hot standby or load balancing services. Additionally, link integrity monitoring may be performed.
Configure interface <interface> with one or more interface addresses.
- address can be specified multiple times as IPv4 and/or IPv6 address, e.g. 192.0.2.1/24 and/or 2001:db8::1/64
- dhcp interface address is received by DHCP from a DHCP server on this segment.
- dhcpv6 interface address is received by DHCPv6 from a DHCPv6 server on this segment.

SLAAC RFC 4862. IPv6 hosts can configure themselves automatically when connected to an IPv6 network using the Neighbor Discovery Protocol via ICMPv6 router discovery messages. When first connected to a network, a host sends a link-local router solicitation multicast request for its configuration parameters; routers respond to such a request with a router advertisement packet that contains Internet Layer configuration parameters.
This method automatically disables IPv6 traffic forwarding on the interface in question.
EUI-64 as specified in RFC 4291 allows a host to assign iteslf a unique 64-Bit IPv6 address.

The following configuration on VyOS applies to all following 3rd party vendors. It creates a bond with two links and VLAN 10, 100 on the bonded interfaces with a per VIF IPv4 address.
# Create bonding interface bond0 with 802.3ad LACP set interfaces bonding bond0 hash-policy 'layer2' set interfaces bonding bond0 mode '802.3ad' # Add the required vlans and IPv4 addresses on them set interfaces bonding bond0 vif 10 address 192.168.0.1/24 set interfaces bonding bond0 vif 100 address 10.10.10.1/24 # Add the member interfaces to the bonding interface set interfaces bonding bond0 member interface eth1 set interfaces bonding bond0 member interface eth2
An example configuration for a Cisco PortChannel to VyOS would be nice
Juniper EX Switch¶
For a headstart you can use the below example on how to build a bond with two interfaces from VyOS to a Juniper EX Switch system.
# Create aggregated ethernet device with 802.3ad LACP and port speeds of 10gbit/s set interfaces ae0 aggregated-ether-options link-speed 10g set interfaces ae0 aggregated-ether-options lacp active # Create layer 2 on the aggregated ethernet device with trunking for our vlans set interfaces ae0 unit 0 family ethernet-switching port-mode trunk # Add the required vlans to the device set interfaces ae0 unit 0 family ethernet-switching vlan members 10 set interfaces ae0 unit 0 family ethernet-switching vlan members 100 # Add the two interfaces to the aggregated ethernet device, in this setup both # ports are on the same switch (switch 0, module 1, port 0 and 1) set interfaces xe-0/1/0 ether-options 802.3ad ae0 set interfaces xe-0/1/1 ether-options 802.3ad ae0 # But this can also be done with multiple switches in a stack, a virtual # chassis on Juniper (switch 0 and switch 1, module 1, port 0 on both switches) set interfaces xe-0/1/0 ether-options 802.3ad ae0 set interfaces xe-1/1/0 ether-options 802.3ad ae0
For a headstart you can use the below example on how to build a bond,port-channel with two interfaces from VyOS to a Aruba/HP 2510G switch.
# Create trunk with 2 member interfaces (interface 1 and 2) and LACP trunk 1-2 Trk1 LACP # Add the required vlans to the trunk vlan 10 tagged Trk1 vlan 100 tagged Trk1
