Cisco 1941 and L2TPv3

Posted on 2014-03-21

I have 2 Cisco 1941 routers, and I want to create a VPN connection (L2TPv3) between them.
The reason I need a L2TPv3 between them, is that I need to forward some VLANs over the link. I want to hook up a trunk port on each side (LAN), and the router should forward the VLANs I want over the link.

Can you please help me with a sample configuration for this?

Hi,

Here is a sample configuration from Cisco documentation. In the example, 198.51.100.100 and 203.0.113.102 are the WAN IP addresses.

I can run up a GNS3 lab if you need more detail.
