Description

Tested on VyOS 1.4-rolling-202110180513

A router with an eth1 interface. VRRP is configured on the interface (with unicast VRRP peer's address configuration)
The interface eth1 is assigned to VRF.

set system host-name 'R-1'
set high-availability vrrp group VLAN11 address '10.0.11.254/24'
set high-availability vrrp group VLAN11 hello-source-address '10.0.11.1'
set high-availability vrrp group VLAN11 interface 'eth1'
set high-availability vrrp group VLAN11 peer-address '10.0.11.2'
set high-availability vrrp group VLAN11 priority '200'
set high-availability vrrp group VLAN11 vrid '11'
set interfaces ethernet eth1 address '10.0.11.1/24'
set interfaces ethernet eth1 description 'VLAN11'
set interfaces ethernet eth1 vrf 'VL11'
set vrf name VL11 table '111'

VRRP is working. But only until reboot:

vyos@R-1:~$ sh vrrp
Name    Interface      VRID  State      Priority  Last Transition
------  -----------  ------  -------  ----------  -----------------
VLAN11  eth1             11  MASTER          200  9m40s
VLAN12  eth2             12  BACKUP          100  9m31s

VRRP stops working after the reboot:

vyos@R-1:~$ sh vrrp
Name    Interface      VRID  State      Priority  Last Transition
------  -----------  ------  -------  ----------  -----------------
VLAN11  eth1             11  FAULT           200  5m1s
VLAN12  eth2             12  FAULT           100  5m1s

If you remove Unicast peer addresses from VRRP settings (change to multicast mode), VRRP starts working again:

delete high-availability vrrp group VLAN11 hello-source-address '10.0.11.1'
delete high-availability vrrp group VLAN11 peer-address '10.0.11.2'
