System DNS
Warning
If you are configuring a VRF for management purposes, there is currently no way to force system DNS traffic via a specific VRF.
This section describes configuring DNS on the system, namely:
DNS name servers
Domain search order
DNS name servers
Use this command to specify a DNS server for the system to be used for DNS lookups. More than one DNS server can be added, configuring one at a time. Both IPv4 and IPv6 addresses are supported.
Example
In this example, some OpenNIC servers are used, two IPv4 addresses and two IPv6 addresses:
set system name-server 176.9.37.132
set system name-server 195.10.195.195
set system name-server 2a01:4f8:161:3441::1
set system name-server 2a00:f826:8:2::195
Domain search order
In order for the system to use and complete unqualified host names, a list can be defined which will be used for domain searches.
Use this command to define domains, one at a time, so that the system uses them to complete unqualified host names. Maximum: 6 entries.
Note
Domain names can include letters, numbers, hyphens and periods with a maximum length of 253 characters.
Example
The system is configured to attempt domain completion in the following order: vyos.io (first), vyos.net (second) and vyos.network (last):
set system domain-search vyos.io
set system domain-search vyos.net
set system domain-search vyos.network
