I can't get L2TPv3 to work from the SM-X backplane interface on an ISR 4K (4331/4451).
The tunnel/session both show established, but no egress packets are being sent.
The same configuration works fine if I move the xconnect to a dot1q subinterface on one of the ISR 4K physical interfaces (i.e. gi0/0/1.199), but I'd rather not have to use a physical cable going from one of the router's interfaces to the SM-X interfaces...
Anyone know if this is the correct method for configuring L2TPv3 on the SM-X backplane interface?
Thanks!
