That would work. Or what about a filter-list/distribute-list pointing to
each neighbor allowing only your routes your generating. So far we've got 4
ways to make sure your not transit. Mannan, see if you can set this up in
the lab (just the tagging part)
1) easy one using an aspath with the permit ^$, deny all (route-map way)
2) setting the no-export community incoming from each neighbor
3) tagging the routes incoming from each neighbor and denying that tag out
your other path
4) distribute-list/filter-list on the neighbor statement
Any other ways?

Something else came on my mind, but I need to check it. How about tagging
the routes on the edge bgp routers and then on the other end deny those
tagged routes to outside world???
