Hi Lukas,

We are settling on 03.16.03a, however the 2nd DC is still in build so
I haven't bumped this up yet. Concentrating on getting the config
working for now.

Well neither seem to be woorking. Happy to use either that will work.
The documentation seems incorrect, so I don't think I have much choise
but to go through trial and error.

Yeah we are running rapid per-VLAN spanning-tree here.

I have had various combinations working between pairs of
ME3600s/ME3800s and obviously port based with ASR920s, but this mix of
ASR920 to ME3600 is giving me stick! EPL and EVPL are metro/carrier
ethernet improvements on port-based pseudowires using EVCs and EFPs on
a specific port. I am simply trying to create pseudowires between a
bridge-domain on each PE, not a specific port or EFP, that will carry
the rapid PVST frames.


Cheers,
James.
