Well, again in the archives (so you probably know already) I saw a comment
which was that the addresses are always sent by dlsw in non-canonical format
- doubt that helps though.

Actually, I've got a related question:

if I config. the following:

r1:

(NO source-bridge ring-group here)
dlsw local-peer peer-id 10.1.1.1 (yep, I know it's better using a loopback
as the id)

dlsw remote 0 tcp 10.1.1.2
dlsw bridge-group 1

int e0
ip address 10.1.1.1 255.255.255.0
bridge-group 1

bridge 1 protocol ieee

r2:

source-bridge ring-group 75

dlsw local-peer peer-id 10.1.1.2
dlsw remote 0 tcp 10.1.1.1 lf 1500

int to0
ip addr 10.1.1.2 255.255.255.0
source-bridge 2 2 75
source-bridge spanning

Q: How do the frames pass from r1 to r2 ? Can sb. confirm (or set me
straight) that they are translated from ethernet to token ring & visa-versa
?

Q2: If I add the command 'source-bridge ring-group 75' to r1 does it mean
that the frames now cross the link & arrive at the destination UNtranslated?

I've seen so many config.s with one or the other (ie the 'source-bridge
ring-group' command both on the ethernet router & not).

In CCBootcamp lab 16, they have a q. about dlsw translational bridging and
there is NO 'source-bridge ring-group' on the ETHERNET router.
However, on one or two of the earlier CCBootcamp labs there was this
command.

I obviously need to pin this one down 'cos again it impacts crucially on
filtering...

Any ideas anybody?

Mark

P.S. Sorry Jeff, I've probably more confused than you!
