Advertising route from cisco 6509

Hi all,

on my core router I have few peer's with my clients and few peer's with upstream providers.

I have prefix list and route maps for my upstream providers.

One client advertise to cisco his subnet with prepend's AS AS AS x.x.x.x/x (backup link)

I want to advertise this subnet to my upsream providers, but I get the same route without prepend's from other peer and  Cisco advertising to upstream provider the best path to route, not AS AS AS x.x.x.x/x

How can I change It?

Thanks!

Hi,

You can create one more route-map with prefix-list and decrease local preference of this prefix to lower than the prefix received

with path prepending.

So the route prefered in your bgp table will be with prepending and cisco will advertise that prefix only.

another approach is you can add some community to prefix received with prepending and allow only that community to upstream provider.

Please feel free to write for any more query
