Router L2 extension Problems

[Fernando Ramiro]

Anyone know how i can establish a lan extender between 2 routers conected wit subinterface on wan port in encapsulation dot1q. I need to host connected in R1 ping host connected in R2 but in same network.

[Fernando Ramiro]

 But you use connection between router with dot1q on vlan 20!?

 Xconnect is not support for SVI in etherSwitch.

""L2TPv3 xconnect is not supported on an EtherSwitch module. This limitation is also applicable to switch virtual interfaces (SVI) that are physically terminated on an EtherSwitch module interface.""

i made this:

on r1 i have one FW 10.75.76.254 connect in 1 port, vlan1 10.75.76.253 and i can ping 10.75.76.254 in r1 router, but i cant ping 10.75.76.254 in second router, i have vlan 1 10.75.76.252 and one host 10.75.76.251. I can ping 10.75.76.253 on host 10.75.76.251, but i have miss GW on FW interface, but if i configure i have no internet access. Have anyway with routes to second router ping FW 10.75.76.254!?
