Peter,
I got to talking with Chuck L, last night and he suggested a tunnel
over
the BVI interface on R6(the trunk sub-interface) which worked. Here is
some ASCII art(I hope it survives)of what I'm talking about before using the
tunnel configuration as well as the relevant router configs. I also captured
some of the debugs from a "debug isis adj".
Once the BVI configuration is in place the interfaces are only captured
sending L1/L2
LAN IIH(hellos) on the connected interfaces.
Any thoughts... Now as I mentioned I am able to get this working using a
tunnel
over the BVI... what I'm trying to figure out is why this isn't working
over the BVI.?
TIA
Nigel
