IBGP Route Path Defining to EBGP

[prakalaathan]

Hi All,

I have a two different ISP s configured BGP with Core Router. I have to set path for some ibgp sessons goes through isp1 and remainig ibgp sessions goes through  isp2 and If one isp down means another isp have to take over all ibgp sessions.

I tried Next-hop and As path but not working properly.

How to achieve this..?

Please help me to Solve this.

PFA for Scenario.

Thanks...,

Prakalathan.

It's not clear from your diagram what you are trying to do.

You only have one router connecting to both ISPs so where does IBGP come into ie. where you are running it, between which routers.

What are you trying to do, is it to influence traffic coming from the ISPs to you or traffic going to the ISPs from you ?

Hi Marshall,

Thanks to relpy.

I'm trying to achieve both incoming and outgoing traffic of client 1 &2 through ISP1 and Client 3&4 through ISP2 .

If ISP1 fails, ISP2 take care all clients in network.

IBGP sessions among core and client routers and EBGP between Core and ISP1, ISP2.

Thanks.,
