Send the traffic coming from the L2VPN into a layer3 sub-interface

Hi  WDNJSQ，

If you want the traffic from L2VPN goes into L3VPN, you have to use Virtual-Ethernet port instead of the Physical port. For example, the traffic from L2VPN in Virtual-Ethernet0/2/0.204 (vlan-type dot1q 204) will go into the L3VPN in Virtual-Ethernet0/2/1.204(vlan-type dot1q 204), because their main ports Virtual-Ethernet0/2/0(l2-terminate) and Virtual-Ethernet0/2/1(l3-terminate)are bind with the same “ve-group 1”

undo l2 binding vsi XXX

interface GigabitEthernet0/2/1.204

 undo ip binding vpn-instance YYY

#

interface Virtual-Ethernet0/2/0

 ve-group 1 l2-terminate

 quit

#

interface Virtual-Ethernet0/2/0.204

 vlan-type dot1q 204
