Thanks Sean! Please see in-line: > Don't do it on the RE, unless you want problems. Marlon: But would this be an option if I wanted to? It seems to me that this is not even an option.
I also remember running VPLS without it (no-tunneling-service command).

If I don't need it for VPLS, then maybe I don't need it for bunch of other stuff? Where is the delineation? Thanks again.
