BGP - restricted 0 0 route redistribution

[majick]

We are planning to redistribute a 0 0 internet route into our IPeFR (AT&T MPLS) cloud, but only want a select few sites to see the advertisement. Let's say we have sites A-D. We want to redistribute the 00 route from A and want B to use the path, but not C&D.

What would be the cleanest way to achieve this goal?

At sites that you won't advertise the default route you can use a routing policy to deny the default route in the specific neighbors:

route-map deny-default deny 10

match ip address prefix-list prefix-list

!

route-map deny-default permit 15

!

ip prefix-list nega-default seq 5 permit 0.0.0.0/0 le 32

I think this can work.
