Network topology is as below
ce ---------- PE1 (C7200VXR) -------- MPLS Cloud ------- PE2 (C7200VXR) ------- ce
vlan 100 vlan 20 vlan20 vlan 100
vlan 200 vlan 200
is it possible for vlan 20 of PE to carry CE's VLANs ?
if it is not possible, could you guys tell me the reason or doucment ?
I know vlan 20 of PE is the service tag. and CE's vlans(vlan 100, 200) are customer's tag
Of course, without vlan in PE (it is port base), it is possible to carry CE's ethernet trunk
IOS : C7200VXR 12.2 33(SRD5)
Thanks & regards
If I understand correctly, is your PE1 mpls enabled. If so your service instance could look like the following
service instance 200 ethernet
encapsulation dot1q 100 second dot1q 200 (only if double tagged traffic)
encapsulation dot1q 100
rewrite ingress tag pop 1 symmetric
xconnect 22.214.171.124 encapsulation mpls
Then you would have a seperate service instance for vlan 200 if two separate vlans
Hope I was on the correct track
I know that service instance config is only used for C7600 ES Line Cards and SIP Series.
is it effective to use service instance on C7200 Routers ?
I know that the config could be put on C7200 12.2 (33) SRD5.
But, I know it doesn't work on C7200.
Am I right?
its not possible since your xconnect is on an access subinterface, hence no tag is carried. I did this on an ME in a q-in-q setup. my configs on the ce facing port was like this:
switchport access vlan yy
switchport mode dot1q-tunnel
