Hi, I have a simple lab setup for testing the L2TPv3. Diagram is attached.
The router simulated PCs (192.168.10.1 and 192.168.10.2) just can not ping each other. Here below are the comfiguration of the 2 routers. I tried to put in "ip pmtu" under pseudowire-class; I tried to adjust-mss under interface of the two router simulated PCs to 1400 or even 1360, none of them changed a thing.
