good morning everyone,

I had practice lab requirement as follows:

Assume that only mac 4000.4000.4000 and 4000.4000.4001 exist on the T/R
between R1 and R5. Configure R1 and/or R5 such that explorer traffic is
limited to only the mac address:

I thought I could fulfill this requirement with the following command on R1

dlsw remote-peer 0 tcp 192.168.3.3 dest-mac 4000.4000.4000

and a similar command on R5.

But, the solution used:

Dlsw icanreach mac-exclusive
Dlsw icanreach mac-address 4000.4000.4000 mask ffff.ffff.fffe

I don't have T/R in my lab so I can't test this but I'm wondering what's the
difference between these 2 techniques?

Any advice or insight is greatly appreciated. Thanks, dt
