Re: Conditional Advertise

Hmmmm, hmmm... So that is. Wonder when that happened. Old notes I
guess. :)

Ok, well, if one is local you can match a prefix-list and an interface,
although I'm not sure whether it would imply a false condition
though.... because one route wouldn't be AND the interface.

The "continue" condition is added in although I'm not sure that's a
mutually exclusive thing in this case.

In other words if you match prefix one and continue then yes you'd have
to match prefix 2 in the next clause to do anything... But what happens
if you match prefix two by itself? Would that still count.

Unfortunately, I have to head out to the circus with my little girls
right now, so I don't have time to lab that one up, but if someone else
wants to do it and report back that would be cool!
