L2VPN Interworking Notes
L2VPN Interworking
– Mechanism to connect two different layer 2 protocols over a L2VPN network
R1(config)# pweudowire-class ABC
encapsulation mpls
interworking ip
int s0/0
encapsulation ppp
xconnect 3.3.3.3 100 pw-class ABC
XR Router
l2vpn
pw-class ABC
encapsulation mpls
interworking ip
xconnect group GROUP1
p2p R1-to-R3
int g0/0/0/0
neighbor 3.3.3.3 pw-id 100 pw-class ABC
Frame-relay special scenario
R2(config)# int s0/0
encapsulation frame-relay
do sh frame-relay pvc
-> To get the DLCI information
frame-relay interface-dlci 200 switched
connect fr x0/0 200 l2transport
xconnect 1.1.1.1 100 encapsulation mpls
During the lab, you will only be asked to configure VPLS on the XR routers
– All other L2VPN configuration will be done on the IOS routers
-> Virtual 7200 for IOS doesn’t support VPLS
sh mpls l2transport vc <id> (IOS)
sh l2vpn xconnect [detail] (XR)
