Balmik has email this nice solution to me which I would like to share
with the group.
Balmik, I hope you don't mind that I send this to the group.
I have tested this on my lab and the results in various situations on
different platforms
Situation 1. It only checks line 10 of the route-map, and ignores the rest.
Situation 2. It does a OR. So both routes have to dissapear to remove
the default instead of one.

I read that outbound BGP route-maps only are supported. I would say
this is a outbound BGP route-map. The only different from standard
advertisement is de conditional default. Maybe it is only intended for
match and set operations on advertised routes.

I'm not able to test this at the moment, but can I suggest you try a
CONTINUE route-map statement to try and get an AND working?
Something like a
Route-map XXX permit 10
Match ip address prefix-list 1
Continue 30
Route-map XXX deny 20
Route-map XXX permit 30
Match ip address prefix-list 2
I don't know if "continue" will work for these kinds of route-maps, but
it's worth a try - if it works, then you can post it to GroupStudy. I
just didn't want to post a "perhaps" email to the group without testing
it, and ending up wasting people's time :)
