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)
R1 R2
sw1 sw2
some recommendations?
