I wanted to create a backup link for a network using a P300 bridge. The current network has two 10 gig links going between two buildings, but construction is set to start soon, that could cut the fiber stretching between. One option was to use the P300 bridges to create a backup link between the two building, which would become active in case of a failure in the fiber links.
We are currently stretching maybe 12 vlans between the buildings. The goal was to have all data go over the 2×10 gig links, and Spanning-tree block the other vlans from using the Bridge. I increased the STP port cost on each side and brought up the bridges – and both fiber links and bridge were forwarding, causing a loop. It took a bit to understand, but according to Ruckus their Gateway bridge detection mechanism basically stops STP and LACP from forwarding. I found the below help doc from Ruckus which gave the command to disable this feature.
