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
This is the show version
