[c-nsp] SVI dot1q tag stripping behaviour

[Jason Lixfeld]

Assuming the following configuration:

PE1 (7600):

!
interface Loopback0
 ip address 1.1.1.1 255.255.255.255
!
interface GigabitEthernet0/1
 switchport trunk encapsulation dot1q
 switchport mode trunk
 switchport trunk allowed vlan 100
!
interface vlan 100
 xconnect 2.2.2.2 100 encapsulation mpls
!

PE2 (any MPLS capable IOS device):

!
interface Loopback0
 ip address 2.2.2.2 255.255.255.255
!
interface GigabitEthernet0/10
 no switchport
 xconnect 1.1.1.1 100 encapsulation mpls
!

I don't have my lab or a sniffer in front of me to test this, so maybe someone knows off the top of their head.  Would the SVI on PE1 strip off the vlan 100 tag before it forwards frames along the xconnect towards PE2 or PE2 forward vlan 100 tagged frames from the PE1 side of the xconnect out Gi0/10?

Thanks in advance.
