Bridge interface randomly disable itself
Closed, InvalidPublicBUG

Description

This has happened to me twice now from a different version of the rolling releases and could not figure out what causes it.

The bridge interface(s) status changes from u/u to A/D.

karlo@fwvyos:~$ show interfaces bridge 
Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down
Interface        IP Address                        S/L  Description
---------        ----------                        ---  -----------
br3              10.0.3.1/24                       A/D  management gateway
br4              10.0.4.1/24                       A/D  backbone gateway

Here is the bridge config:

karlo@fwvyos# show interfaces bridge | commands 
set bridge br3 address '10.0.3.1/24'
set bridge br3 aging '300'
set bridge br3 description 'management gateway'
set bridge br3 hello-time '2'
set bridge br3 max-age '20'
set bridge br3 member interface bond0.3
set bridge br3 member interface eth2
set bridge br3 priority '0'
set bridge br4 address '10.0.4.1/24'
set bridge br4 aging '300'
set bridge br4 description 'backbone gateway'
set bridge br4 hello-time '2'
set bridge br4 max-age '20'
set bridge br4 member interface bond0.4
set bridge br4 priority '0'

Here is the bonding config:

karlo@fwvyos# show interfaces bonding bond0 | commands 
set description 'Core: see eth4 and eth5'
set hash-policy 'layer3+4'
set member interface 'eth4'
set member interface 'eth5'
set mode '802.3ad'
set vif 3
set vif 4

When rebooted the VyOS, the bridge interfaces stayed in A/D state. The workaround that I found is to manually set the bridge interfaces to disable then commit.
Afterwards, delete the interfaces bridge disable option then commit. After this, the bridge interfaces state will change to u/u and traffic will flow again.

set interfaces bridge br4 disable
commit
delete interfaces bridge br4 disable
commit
