Craig,
The correct method is:
dlsw icanreach 4004.0000.4444 mask ffff.0000.ffff
Please see DLSW+ command guide for "dlsw icanreach":
mask
(Optional) MAC address mask in hexadecimal h.h.h. The "f" value represents
the "care" bit and the "0" value represents the "don't care" bit. The mask
indicates which bits in the MAC address are relevant.

would it be ?
dlsw icanreach 4004.0000.4444 mask 0000.ffff.0000
or
dlsw icanreach 4004.0000.4444 mask ffff.0000.ffff
I have seen the mask to mac addresses both ways. I am trying to figure this
out. It appears the bootcamps have it 4004.0000.4444 mask ffff.0000.fffff
anyone know?

All,
Q) You are trying to eliminate explorer packets from
traversing the network. Configure R1 so that explorers
for MAC address 4004.XXXX.4444 do not get sent through
the network. This addresss should be exclusive to R1.
I was pondering about this. And I came to a few
conclusions, but I am not sure if they are correct.
1# We could implement a MAC to PEER mapping statement
on R3, with "dlsw mac-addr"
NB: this doesn't allows us the flexibility of MAC
classification.
2# We could implement "dlsw icanreach mac-exclusive"
on the core router.
NB: but this would then propagate to all other peers
as well.
Any suggestions/thoughts/insights?
