Joseph,
        Can you send the output of a "show ip route" along with your BGP
configuration? Also I'm curious as to why you did do step 3. Were you
trying to filter off other routes?

Yes, I did all of that. I tried:

1. Doing a show ip route isis to get the routes

2. I specified the routes with the network command under bgp

3. I created a prefix list for all the routes and matched a route-map to

it, and specified the route-map in a neighbor statement so I could
advertise the routes to the neighbor

The ISIS routes I am supposed to advertise are all L1's.

Joseph,
        Did you try using the network statement?

I have a requirement to get ISIS-learned routes into the BGP tables of
BGP neighbors without using redistribution or aggregation commands. I'm
stumped.

I tried advertising the routes as backdoors but that didn't work.

I specified the prefixes in a prefix list and referenced by a route-map
and applied the route-map to the neighbor command and that didn't work.

Any ideas?
