On our PE Router/Switches we MUST run MST
Customers are directly connected to our PE
Now we are looking for a solution how to isolate Customer STP (RPVSTP, MST, Legacy) from our MST and to transport Customers BPDUs transparent via EoMPLS to the ohter customer-site.
This is not a Problem when using Port-Based EoMPLS, the we can do following config
xconnect c.c.c.c encapsulation mpls
But if we have to to VLAN-Based EoMPLS I have no Idea how to do this ?
As I know there is now way if running MST to disable STP for a particular VLAN, and its also not possible to configure l2protocol-tunnel in this scenario.
Also a BPDU-filter does not help, because customer wants to have his BDUs transported ?
Any Idea ?
Konfig on N-PE
!## we need to run MST on the Box (so in my opinion that means that every VLAN is assigned to one MST-Instance, per default MST0
spanning-tree mode mst
spanning-tree mst configuration
!## I think this is no possible to configure if MST is running
!## no spanning-tree vlan 100,200
!## l2protocol-tunnel stp config only allowed on Switchport ??
!## the way how to configure VLAN-based MPLS on "normal" LAN-Line-Card
encapsulation dot1q 100
xconnect a.a.a.a encapsulation mpls
encapsulation dot1q 200
xconnect b.b.b.b encapsulation mpls
