Redundant VPN Connection Question, Diagram Included

[jgiardina]

Hi, I have a few questions regarding RRI and HSRP. I think I have the jist of this, but would like to run it by someone.

In the attached diagram, I simply have two Internet connected routers (Router A and Router B) that will establish IPSEC tunnels to PIX A.

The inside interfaces on Router A and Router B will be part of the HSRP group to provide the IP 172.16.1.1 as the default gateway on PIX B.

I can establish the IPSEC tunnels to PIX A, as well as configure HSRP on the 172.16.1.0 network.

I guess my question is:

How do I configure RRI on Router A and Router B to get this solution working?

Also, is this the recommended configuration for this type of redundant IPSEC connectivity?

Sorry, I mistyped the 172.16.1.0 network's internal IP addresses. The devices should be 172.16.1.2, .3, and .4.

I gave 172.16.1.2 to two devices, but the basic idea I am looking for should not matter.
