Thomas,
You could configure it this way, however let's think about the question. If
you use the loops and the Ethernet fails, you can still have a DLSW peering
session between the two routers - right? You will never get circuit
establishment, however because the Ethernet is down. Now, to be pedantic it
could be argued that this does not satisfy the question, as DLSW could still
be seen to be up even when the Ethernet was down. I guess the gist of what I
am trying to get across is that if you configure it using the IP of the
Ethernet interface you would not be wrong. If you used the loopback you
could be wrong (or right) depending on the intent of the question. My
advice, always play it safe. Remember this is not necessarily what we would
do in the real world, it is what we would do to get us to pass!
Cheers,

Subject: dlsw
when configuring dlsw, and i am asked to "configure dlsw between router 1's
ethernet 0/0, and router 2's ethernet 0/0",
do i need to use the ip addresses for those particular interfaces ( e0/0 on
r1 and e0/0 on r2 ) for dlsw local-peers and remote-peers???
i thought that i could just use configured loops on each of the routers, and
let "bridge-group 1" on the interfaces takes care of the rest, and still
accomplish dlsw connectivity.
thanks,
tom
