L2TPv3 help required

Good day all

I'm having an issue implementing L2TPv3 between two sites. I am issuing the xconnect command to the subinterface which I want to connect, and I get this error:

"Incompatible with ip address command on Fa0/0.2"

Now I need the IP on the interface as hosts point to it for routing purposes. Is there a way to work around this problem?

Thanks

Hello Jason,

unfortunately you would need a second subinterface using same Vlan-id on a different Fastethernet port to provide both L2 and L3 services to the same vlan.

something like

int fas0/0.2

enc dot1q 2

ip address 10.2.2.1 255.255.255.0

int fas0/1.2

enc dot1q 2

no ip address

xconnect ...

with both interfaces connected to L2 trunk ports of an external LAN switch.

Hope to help

OK I've managed to get the commands entered, but I cannot ping (or even ARP) for hosts the other side of the link.

One the one side of the link I am running the xconnect on a subinterface, but on the other the xconnect is on the main interface (there are no subinterfaces). Could this have something to do with the problem?
