Description

Bridge: the isolation option disappears after reboot
To reproduce
Add a bridge and reboot the router

set interfaces ethernet eth1 vif 21
set interfaces ethernet eth1 vif 22

set interfaces bridge br1 member interface eth1.21 isolated
set interfaces bridge br1 member interface eth1.22 isolated

Check before reboot:

vyos@r1# bridge --json -d link | jq '.[] | {ifname, isolated}'
{
  "ifname": "eth1.21",
  "isolated": true
}
{
  "ifname": "eth1.22",
  "isolated": true
}

Reboot the router and check again:

vyos@r1:~$ bridge --json -d link | jq '.[] | {ifname, isolated}'
{
  "ifname": "eth1.21",
  "isolated": false
}
{
  "ifname": "eth1.22",
  "isolated": false
}

It seems the bug even if configuration applied in one commit:

set interfaces ethernet eth1 vif 21
set interfaces ethernet eth1 vif 22
set interfaces bridge br1 member interface eth1.21 isolated
set interfaces bridge br1 member interface eth1.22 isolated
commit

check:

vyos@r1# bridge --json -d link | jq '.[] | {ifname, isolated}'
{
  "ifname": "eth1.21",
  "isolated": false
}
{
  "ifname": "eth1.22",
  "isolated": false
}
