I have what I thought was a pretty simple config - Two VLANs on two GigE interfaces, on a MX240 running 9.4R2.9 which are cross-connected within the MX using a l2circuit.

If I remove the 'vlan-ccc' encap from the units and assign an IP, we can ping to something on the other end - So at least we know end-to-end works on both interfaces. Once it's reassembled as a l2circuit, there is no connectivity between the two end points. I'm sure it's something pretty elementary, but I can't determine what it is. Is there a way to sniff or capture traffic on the l2circuit to see what is going on?


The VLAN numbers at both ends of the l2circuit need to be the same for it to work.

This is a very poorly documented limitation of the l2circuit feature.
