Hi!

Version: VyOS 1.5-rolling-202409300007

After host rebooted isolation does not up.

Woking

Vyos int bridge memebers:

set interfaces bridge br1 member interface eth1.21 isolated

set interfaces bridge br1 member interface eth1.32 isolated

bridge -d link

21: eth1.21@eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br1 state forwarding priority 32 cost 5

hairpin off guard off root_block off fastleave off learning on flood on mcast_flood on bcast_flood on mcast_router 1 mcast_to_unicast off neigh_suppress off neigh_vlan_suppress off vlan_tunnel off isolated on locked off mab off mcast_n_groups 0 mcast_max_groups 0

24: eth1.32@eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br1 state forwarding priority 32 cost 5

hairpin off guard off root_block off fastleave off learning on flood on mcast_flood on bcast_flood on mcast_router 1 mcast_to_unicast off neigh_suppress off neigh_vlan_suppress off vlan_tunnel off isolated on locked off mab off mcast_n_groups 0 mcast_max_groups 0

Make reboot and …

After host rebooted isolations does not up.

Main config still here:

set interfaces bridge br1 member interface eth1.21 isolated

set interfaces bridge br1 member interface eth1.32 isolated

But if i do bridge -d link i have next output and loops

21: eth1.21@eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br1 state forwarding priority 32 cost 5

hairpin off guard off root_block off fastleave off learning on flood on mcast_flood on bcast_flood on mcast_router 1 mcast_to_unicast off neigh_suppress off neigh_vlan_suppress off vlan_tunnel off isolated off locked off mab off mcast_n_groups 0 mcast_max_groups 0

24: eth1.32@eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br1 state forwarding priority 32 cost 5

hairpin off guard off root_block off fastleave off learning on flood on mcast_flood on bcast_flood on mcast_router 1 mcast_to_unicast off neigh_suppress off neigh_vlan_suppress off vlan_tunnel off isolated off locked off mab off mcast_n_groups 0 mcast_max_groups 0

After manual

sudo bridge link set dev eth1.21 isolated on

sudo bridge link set dev eth1.32 isolated on all work properly

Is it any capability to have working β€œisolated on” bridge member interfaces always after host rebooted?

Hi!
UPD.

I`ve found a solution in VyOS Documentation.

So, what exactly did you add to postconfig?

@syncer
I just added in each interface via nano like this:

sudo bridge link set dev eth1.21 isolated on
sudo bridge link set dev eth1.32 isolated on

That`s all. After reboot I see β€œisolated on” if bridge -d link executed. It works in my case :+1:

Thanks for sharing the solution! i will see if we can fix that so it will not require anything

please, check with a update version , I’ve tested this configuration and works as expected :

vyos@vyos:~$ show configuration commands | match br
set interfaces bridge br0 description 'test-iso'
set interfaces bridge br0 member interface eth1.10 isolated
set interfaces bridge br0 member interface eth1.20 isolated

value on our bridge :

vyos@vyos:~$ sudo bridge -d link
7: eth1.10@eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br0 state forwarding priority 32 cost 100
    hairpin off guard off root_block off fastleave off learning on flood on mcast_flood on bcast_flood on mcast_router 1 mcast_to_unicast off neigh_suppress off neigh_vlan_suppress off vlan_tunnel off **isolated on** locked off mab off mcast_n_groups 0 mcast_max_groups 0
8: eth1.20@eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br0 state forwarding priority 32 cost 100
    hairpin off guard off root_block off fastleave off learning on flood on mcast_flood on bcast_flood on mcast_router 1 mcast_to_unicast off neigh_suppress off neigh_vlan_suppress off vlan_tunnel off **isolated on** locked off mab off mcast_n_groups 0 mcast_max_groups 0

logic is present in our code :
