RE: More DLSW peer questions...

I also just tried this with

----BOT-----------4500-----------R1
   group70 grp70bdr grp80bdr

and the icanreach stuff is only sent from a group-peer to it's border peer -
it's not sent to the neighbor border peer.

ie

BOT has a dlsw icanreach-mac, 4500 learns of it (unconfirm) but doesn't pass
it to R1 regardless of whether R1 is a grp70 peer or a grp80 bdr-peer.

I guess once there's a station on either remote segment sending out explorer
frames the reachabilities/capabilities get passed???

I gather this won't happen unless there's a canureach sent though...

R2 is border - it will forward CUR to other borders and peers in its own
group. R3 (remote peer) will recieve CUR and respond with ICR which is then
relayed back to R1. R1 will receive ICR and based on information in the ICR
will establish connection to R3 for frames to flow.
