Greetings, We are thinking about leveraging the ME3600 platform to provide MPLS connectivity between two switch fabrics, connecting arbitrary VLANs on each end to each other in a redundant fashion. We have a 2 switch fabric at location A, with each switch connected to a different ME3600 via trunk. At location B, the same config is replicated.
We want to be able to connect arbitrary VLANs to each other on MPLS xconnects -- IE, vlan 12 on side A is in the same broadcast domain as vlan 23 on side B. My main concern is redundancy and loop prevention -- we want to build two xconnects per pairing, one on each ME3600 per location, and are trying to work out how STP protocols will work and interop in this situation. If MSTP is used on both sides (different regions), should we just build an xconnect for vlan 1 to vlan 1, and transport the BPDUs? What is R-PVSTP is used on one side, and MSTP on the other? How can we ensure that the MST0 BPDU is replicated into each PVST instance when we are doing the mapping? -- Brandon Ewing ([email protected])
