[c-nsp] VPLS and SSTP or STP

[samuel vuillaume]

HI guys,

Just a quick question. Here's my context
---------------------------------------------------

CPE1----------*QinQ + L2PT port* (7600)------VPLS-----------(7600) *Trunk
port* ------NNI---------CPE2

CPE1 and CPE2 run PVST+ and both 7600 don't run any STP

On QinQ + L2PT port (7600), i ran a debug netdr and:

- i can see PVST+ traffic coming CPE1

- i can't see PVST+ traffic coming from CPE2 ((from (7600) Trunk portChassis)

On (7600) Trunk port, i ran the same debug, debug netdr and:

- i can see L2PT traffic coming ((QinQ + L2PT port (7600)) originated from
CPE1

My question is on a *basic Trunk port* (as above facing CPE2), How VPLS
should handle those SSTP BDPUs (01:00:0C...CD) ? Apparently they're dropped,
and only

untagged STP BPDU 01:80...... are allowed.


IMPORTANT: the NNI VLAN is already double tagged.

Any thoughts would be appreciated....

tks
