G'Day,

I have a fairly simple question for someone who knows regarding the
"neighbor advertise-map non-exist-map" statement.

I am advertising from 3 seperate locations (Running IBGP) routes into the
same AS (UUNET) and would like to use this statement to only advertise
routes once into UUNET unless one of the links are down and then they go out
one of the other locations.

To achieve this do I need to use 2 statements per UUNET peer on each router
or would there be some way to do this using the route-maps?

For example if i did the following would this be correct:

AS1234
neighbor 1.1.1.1 advertise-map INTERSTATE1 non-exist-map INTERSTATE1
neighbor 1.1.1.1 advertise-map INTERSTATE2 non-exist-map INTERSTATE2

AS2345
neighbor 2.2.2.2 advertise-map INTERSTATE1 non-exist-map INTERSTATE1
neighbor 2.2.2.2 advertise-map INTERSTATE2 non-exist-map INTERSTATE2

AS3456
neighbor 3.3.3.3 advertise-map INTERSTATE1 non-exist-map INTERSTATE1
neighbor 3.3.3.3 advertise-map INTERSTATE2 non-exist-map INTERSTATE2

If I need to explain this further please let me know..

Cheers
