[c-nsp] BGP - filtered 00 route redistribution

[Jonathan Crawford]

That will reject any route, not just your 0/0 route. Remove the "le 32" to only match a default (0.0.0.0/0 exact).

Subject: [c-nsp] BGP - filtered 00 route redistribution

Hello All,

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

I think this filter would work. It would require updates to every
router which isn't the worst thing, but looking for alternatives.

route-map deny-default deny 10
match ip address prefix-list prefix-list
!
route-map deny-default permit 15
!
ip prefix-list deny-default seq 5 permit 0.0.0.0/0 le 32
