We have a scenario where we have 2 Cisco switches, the core switch is connected to the edge switch via a Terabeam 60Ghz link. As a backup we have an RB333 setup with a WDS bridge.
We have MSTP (802.1s) configured on all switches, and have the core set as the MSTP root.
The idea is that MSTP will have the Terabeam link in a forward state when both are connected as it has a better priority and the RB333 will be blocked, then if the Terabeam link fails for some reason the RB333’s port will go into a forwarding state.
When connected via the Terabeam link, 802.1s functions normally and shows the core switch as the root bridge, however when we connect via the RB333 link (wds-bridge) the MSTP stops functioning correctly and shows the edge switch as the root.
We do not have any STP/RSTP/MSTP configured on the RB333’s as the switches should handle the MSTP.
It appears that RouterOS is not passing the BPDU packets correctly. Has anyone experienced this before ???
And does anyone know how to solve this problem ??
