[c-nsp] 7600 VPLS and specific second-dot1q .. only ES+ can do it?or ASR9k i guess..

Daniel,

On 7600 for VPLS you need ES+ (or ES20/SIP400) modules on the core
facing side. If you want to match on 2nd dot1q tag, you would also need
to use the newer EVC (service instance) syntax, which would require ES+
module also on the UNI.
Note that there are now combo ES+ modules with both 10GE and 1GE ports
on the same linecard so you can use the same module for the core (NNI)
facing and UNI facing ports.

This is natively supported on ASR9K.

I've been searching Cisco documentation ( and this archive ), and i want
to confirm something with respect to 7600 VPLS

The following example shows how to create a Q-in-Q AC, with IOS XR

RP/0/RSP0/CPU0:router# configure
RP/0/RSP0/CPU0:router(config)# interface GigabitEthernet 0/0/0/0.2
RP/0/RSP0/CPU0:router(config-subif)# l2transport
RP/0/RSP0/CPU0:router(config-subif)# encapsulation dot1q 200
second-dot1q 201 RP/0/RSP0/CPU0:router(config-subif)# commit
RP/0/RSP0/CPU0:router(config-subif)# exit RP/0/RSP0/CPU0:router(config)#
exit

It seems to me that the only way to do  this is with a 7600 with a ES+
card, and not in a CAT LAN card ( WS6748).. so if a customer needs to do
this, they need to migrate their hw and their configuration, from
something like this:.

l2 vfi name manual
 vpn id yy
 neighbor x.x.x.x encapsulation mpls

interface GigabitEthernet X/X ( lan card port )  switchport  switchport
trunk encapsulation dot1q  switchport trunk allowed vlan yy  switchport
mode trunk

 interface Vlanyy
 no ip address
 xconnect vfi name


to this:

l2 vfi name manual
 vpn id yy
 neighbor x.x.x.x encapsulation mpls

interface GigabitEthernet X/X ( es+ port ) port-type nni  switchport
trunk allowed vlan none  switchport mode trunk service instance yy
ethernet  encapsulation dot1q 200 second-dot1q yy  bridge-domain yy

is that correct?
