Hey everyone...

I am attempting to set up a remote network on the same subnet via IP Cloud using L2TPv3.

I have the tunnel built
Here is the config for both ends:
Having issue with L2TPv3 configuration.
The session is up, but no traffic can pass.

Behind these devices are Cisco Switches then the Servers hang off of the
switch. Each switch has a the same VLAN info, VLAN 601 and the IP address is
in the same subnet.




This is the topology
The configs above are for the 7206 w/ l2tpv3 set-up
Server(1.1.1.3 default gateway 1.1.1.1) -----> 6509 VLAN 601 (int vlan 601 ip address 1.1.1.1) -----> 7206 (ip address 20.20.20.20) -----> WAN <----- 7206 (ip address 10.10.10.10) <----- 3750G VLAN 601 (int vlan 601 ip address 1.1.1.2) <----- Server (1.1.1.4 default gateway 1.1.1.2)


Is there something I am missing?
Do I need some form of routing on the Switches to get the traffic to the router? I assumed since the encapsulation is L2, dot1q, and in vlan 601, AND directly connected that traffic would enter the interface then bind to the tunnel and pass across internet, but that does not seem to be happening.

Any help would be awesome!
