How to test

VyOS configuration:

set high-availability vrrp group WAN address 192.0.2.55/24
set high-availability vrrp group WAN address 192.168.222.222/24 interface 'eth2'
set high-availability vrrp group WAN address 198.51.100.111/24
set high-availability vrrp group WAN interface 'eth0'
set high-availability vrrp group WAN no-preempt
set high-availability vrrp group WAN priority '200'
set high-availability vrrp group WAN track exclude-vrrp-interface
set high-availability vrrp group WAN track interface 'eth2'
set high-availability vrrp group WAN track interface 'eth1'
set high-availability vrrp group WAN vrid '100'

Keepalived conf, expected dont_track_primary and 192.168.222.222/24 dev eth2 and track_interface:

vrrp_instance WAN {
    state BACKUP
    interface eth0
    virtual_router_id 100
    priority 200
    advert_int 1
    dont_track_primary
    nopreempt
    virtual_ipaddress {
        192.0.2.55/24
        192.168.222.222/24 dev eth2
        198.51.100.111/24
    }
    track_interface {
        eth2
        eth1
    }
}

Can we change the CLI and remove redundant words?

set high-availability vrrp group WAN track interface 'eth2'
set high-availability vrrp group WAN track exclude-vrrp-interface
