Redundancy

Hi Experts,

We have 2 ISP's consider SP-A and SP-B. Both are connected to Router. We have default routes on Router to SP-A and SP-B. Router is connected to PIX. Patting has been performed for both the ISP's. Now I need some redundancy on PIX so that SP-A fails SP-B takes over or vice versa. I cant use two PIX. Please let me know the solution.

Cheers,

Nik

Re: Redundancy

One solution is configure SLA probes on the router so that when a tracked object becomes unreachable, a floating static route is activated.

The problem is that you will not be able to use SP-A addresses on SP-B link, and viceversa, that means in practice turn, the router must do the NAT, not the PIX.

It's also tricky because it involves multiple subnets, policy routing etc.

Good luck.
