2 circuits with same ISP, 2 Router, 1 ASA5510, C4510

Unanswered Question
May 22nd, 2007


There are 20 vlans on C4500, I would like to source route 3 vlan traffic to router2 and all other traffic to router1. C4510 is connected to ASA5510 inside interface.

How can I achieve this ?

I have this problem too.

In addition to Bjornar's post, a brief network diagram would help us to understand the topology and suggest you the best possible solution accrodingly.Please paste a rough network diagram.

Thank you very much for your reply.

We don't have AS number to do BGP yet.

Each router has 6M pipe out to single ISP.

router1 is connected to ASA outside, router2 is not connected yet.

I'm thinking of either connecting router2 to another outside interface on ASA to do multi-context or connect router2 to router1 and do iBGP w/HSRP

Then as far as I understand when your routers are connected outside the ASA on separate outside interfaces, the ASA have to do the policy routing :)

However if you apply HSRP and connects rtr1 and rtr2 on the same vlan, then I think you can do policy routing on the routers.

Please check the scroll-bar at the bottom right on every post :)

appreciate your response.

But are you saying you can do PBR on ASA ? If so, how would configure it ?

I realy don't have any knowledge of the ASA.

I know that checkpoint fw support PBR, so the ASA should do so too :)

But my recomendations is that you do this on a router.
