Hi Group,
I am trying to use the default originate neighbor ("neighbor
{ip-address | peer-group-name} default-originate [route-map map-name]")
command to send a default route into AS200. My configs are an follows:
topology

R5#
There are three peers in AS500 two route reflector clients and a single route
reflector. I've only posted R5 and R3's configs, because I think there the
only configs with any relevance. I've read that the host originating the
default route does not need a default to propagate one using the neighbor
default command. Not sure if that's true, so I created a default on R5 to see
if it might make the route propagate. Didn't work. I've tried sync and no
sync. I'm still working on the this one, any help would be appreciated. Also,
underlining connectivity is provided via IGPs, that is, connectivity is ok.
Thanks
Al
