Jay;
You should know this rule:
DLSw+ always sends data in non-canonical format .
So if you have in your exam the following:
you have a router with ethernet interface - R1- and he asked you to
tell remote peers that station with mac Address X is reachable.
so before putting the mac address in ' dlsw icanreach mac-addr ' command
you should convert this MAC address into non-canonical [ because he gave you
a MAC address of ethernet station, i.e. in canonical format ].
Also in case you want to apply a MAC address to dlsw remote-peer command
you should convert the canonical MAC adress given to you to non-canonical
before applying it in the MAC access-list using the keyword "dmac-out"
in the dlsw remote-peer command.
Hope that clarifies your questions and any confusion .
Regards;
Ayman
