Using spanning tree in ms. Redundant scenario with older cisco routers
Hi! Redundant setup with two cisco routers (C1111, fibre, R1 and c819, LTE, R2).
C1111 support #spanning-tree mode ? mst Multiple spanning tree mode pvst Per-Vlan spanning tree mode rapid-pvst Per-Vlan rapid spanning tree mode
but c819 only support pvst.
Two connected ms12x two interface/router (sw1 connects to R1 and R2 and same with sw2). Root=sw1. It have been work ok but it seems when upgrade to fw15 it becomes alot of problems. Known issue with ms and pvst but no alternative on backup router(R2)
