Fred,
Well, for example, the 5.0.0.0 route is in the bgp table with next hop as
137.6.2.17. This route is in the routing table, 137.6.2.16/30 but the 5
prefix is not marked as best in the bgp table. I am trying to do this by
not setting no sync just to test the bgp rules. I thought that since the
next hop is reachable through an IGP then it would be marked as *> in the
bgp table. I can get the route to be marked as *> by setting no sync but I
wanted to avoid using this if I could. I probably just misunderstand the
synchronization rule.
Thanks, Stephen.
