MPLS L2VPN ASR9K and 7600

Hi Ogungbenro,

Can you please post the output of a "show ip cef int" from the 7609.

MPLS L2VPN ASR9K and 7600

Hello ogungbenro wale,

Would you be so kind to verify the output form 7600, since the config part does not correspond to VC you provided output for:

interface gig 3/4.609 <=


Local interface: Gi1/3.609 up, line protocol up, Eth VLAN 609 up <=
