Michelle:
I think I understand your question. After configuring dlsw+ on both routers
and building your basic peerings, you can see both the canonical and
non-canonical addresses depending on which bridge you view. If you do a
"show bridge", you will see the standard non-canonical ethernet address. If
you do a show dlsw reach (that will show the local reachability macs), they
will be in canonical format. The tricky part if determining which
non-canonical address relates to which canonical address. I wouldn't trust
this trick, since you will not have an actual ethernet node on the dlsw peer
in the lab exam.
Also, I ran your conversion just for kicks and I think you are off by a
byte. I get 00-20-30-d0-08-00, you have the same string except 00-00 at the
beginning. I'm not sure what happened here.

RE: More Canonical to Non-canonical in DLSWAha! I just realized, I didn't
say exactly what I meant. If I hard code an icanreach into the peer
statement, then I have to convert it to non-can. yes? And wasn't there a way
to do a show dlsw command to get this conversion without having to perform
it?
I should have made that clear. Not a dynamic icanreach, but a statically
defined icanreach on the peer statement. And then I presume R2 gets it and
tranlates it back for the ethernet group and leaves it as is for the token
ring users.

In this case you would see R1 advertise non-canonical to R2 and R2 would NOT
have to convert it.

----Bridge 1
E0
Bridge 1 E0--- R1 ------------------ R2 ----Ring 1 T0
Ok, More on canonical vs. non-canonical with the icanreach statement
R1 has a peer statement to R2 and wishes to advertise a device that resides
on R1-E0. Mac address is 0004.0c0b.1000
R2 has both token ring and ethernet sna users.
Does the R1 icanreach advertise the native 0004.0c0b.1000? (ethernet,
canonical)? I think that it does not.
So R1 advertises icanreach 2030.d008.0000 (feel free to check my
conversion).
Then does DLSW convert it back on R2 for the ethernet bridge group but not
convert it for the Token ring users?
