PBR & BGP

roland_costea · ‎01-09-2008

Hello!

I have a question! 3 different ISP's are connected with a router! 2 of them are used for data traffic

and the other one for the voice traffic.Behind the router I have 2 IP classes:one generates data traffic and the other voice traffic.The router has full BGP connectivity with all of the providers.

I want to send the voice traffic(and only that one) to the 3rd ISP!How can I do that? My first reaction was PBR! But if I'll try to match the voice class and then "set ip next hop" i'll loose the BGP redundancy!If a destination becomes unavailable through ISP3 i will continue forwarding packets through that link but they will go to nowhere!

My question is,do you know a solution in which i can force the "ip next hop" only if there is an entry in the BGP table with that next hop???

Thanks a lot!

There is an option in ip next-hop

" set ip next-hop verify-availability"

here the availability is checked using cdp,so that must be enabled..

try out this..

you have the option of defining multiple next-hops under the set statement.

But there may be other ways to achieve what you require.
