Ronnie is right. I was not thinking about this correctly. The command
would be on the router that you do not want to send the explorer frames to
(R2). It would be advertised to all peers in the capabilities exchange.
Thanx Ronnie!

Correct me if I am wrong, but I understand the dlsw icanreach mac command to
inform downstream DLSw peers of reachability of a particular mac address.
The downstream peers keep this address cached pointing to the router with
the 'icanreach' command.
The downstream peers will not then send explorer packets upstream looking
for that particular mac because they know (via the capabilities exchange)
that a particular peer can reach that mac. Any stations off of one of the
downstream peers trying to connect to that mac will be answered by the
downstream router locally.
If R2 has the lan to the 4444.4444.4444 mac (which is the way I understand
the senario), why have R1 tell everyone that HE has the mac?
R1-----------R2--LAN - - - mac 4444.4444.4444

R1(config)#dlsw icanreach mac-address 4444.4444.4444 mac-exclusive
This needs to be placed on Router ONE and NOT Router TWO. Don't forget the
mac-exclusive command because this tells the router that this is the only
mac address that I know how to reach. Thus it will not send explorer frames
to its peers looking for other mac addresses.

I think this would work, but I'd like some feedback on this one, too.

How can I stop Router ONE from sending explorer
packets to Router TWO looking for MAC address
4444.4444.4444?
Please email me directly.
