But if you do that won't it appear as:
route-map EXS permit 10
match ip add 101 102
and it will be either 101 or 102?

How about this route-map, so when either one link is down, the route is
withdrawn?
route-map EXS permit 10
match ip add 101
match ip add 102
access-list 101 permit host 172.20.122.0 host 255.255.255.252
access-list 102 permit host 172.20.123.0 host 255.255.255.252

Reading that made me think of another question. This will advertise the
route if at least one of the two connected networks exist. If we wanted
conditional advertisement, but only if both of the networks are there.
I guess I could do two lists for each network, but how would I make it
AND
instead of OR?
Thank you
