RIP into BGP redistribution

Hi,

I have a customer sending me a /25 via RIP v2. I wish to announce this route into an EBGP connection as two /26.

How is the best way to do this?

Suggestions?

Thanks

If you want to advertise 2 /25s then you need to have the /25s appear in your routing table. Probably the most easy way to do this would be to configure 2 /25 static routes. You can then redistribute (or configure BGP network statements) to advertise the /25s.

Gareth,

You might want to try out the BGP Conditional Advertisement feature:

Redistribute RIP into BGP, look for the existence of the /25 in the RIB, and then advertise those /26s...

Let me know how you go.
