I sometimes use it for route redistribution in the protocols that
support it (OSPF, RIPv2, ISIS for example)
Say you have three different IGP's across an Enterprise or a Lab ;-) and
you have a requirement to say, not advertise the RIP routes to IGRP on
the other side of the OSPF domain.
You could mess around with lots of access lists etc but that's time
consuming and a pain in the butt, also very easy to mess up an access
list as I'm sure we all known :-P
So what I do is use a route map and set the tag to say '2' for routes
imported into OSPF from RIP then on the route map from OSPF to IGRP deny
all routes that match tag 2 from being sent.
Easy! :-)
It's also very scalable as there are no access lists, its quick and best
of all you can do the same thing and tag IGRP learnt routes as '3' and
handle them appropriately if needed.
