Hi There,
I have 2x2800 routers with NME-16ES-1G-P - 16-port 10/100 Cisco EtherSwitch Service Module installed in it.
I created L2tp tunnel using Physical interfaces on the routers. It works fine. laptops could ping each other.
Now I Want to create a L2TPtunnel from the router sub interface to another router physical interface.
Following config I applied. Tunnel comes up but the two laptops cant ping.
Following is the Config
Service Module-1
===============
Int fa 1/0/1
Desc laptop-1 having IP 172.16.0.1 255.255.0.0 is connected on this port.
Sw acc vlan 1
Int gi 1/0/2
Desc Internal Dot1q Trunk
sw mode tr
sw trun en dot1q
==========
On Router-1
========
L2tp-class l2tpclass11
pseudowire-class pseudoclass11
encap l2tpv3

ip local interface loopback 0
Int loopback 0

OSPF is running so all the routng is in place. Router 1 can ping router 2 loopback and other IP address.
L2TP tunnel comes up straight away but Laptop-1 cant ping laptop2 and vice versa.
Any sggestion whats wrong in the config.
