Routing to Vendor network and tracking interface failure

[mbroberson1]

Please see attached diagram for more details.

Senario:

You have a connection to vendor/business partner. You have two connections to this business partner. You are runing EIGRP on your internal network and with your routers and core switches. You don't know and don't care what IGP's the vendor is running. They are most likely doing statics. The vendor has two circuits from their routers to their network. If one of the vendors circuits goes down their equipment will failover to using their seconday circuit and equipment.

NOW the BIG question:

How can you configure your company primary router to notice when the vendor primary fails over and instruct your secondary router to take over as the primary path to the vendor network. Your company routers are using HSRP over a L2 link and the primary has static routes pointing to the failover ASA HSRP address of the Vendors ASAs.

I think you will have to do some sort of interface tracking, but not 100% sure.

Thanks!

See if this would be a valid configuration?

No, it's not.

If the interface goes down, HSRP will give control to another HSRP router. The track command has no usability there.

Hi Edison,

Then if the internals on each router is on a different subnet and you wanted to use the HSRP way what best method would you propose? Something other than the IP SLA method.

Thanks,

Brandon,

Honestly, I lost track of what was said on this thread.

A quick read on this thread shows that we don't have an exact set of requirements from you and we are grasping at straws.

My suggestion; bring someone on-site that sits with you and customer one-on-one to come up with the proper solution|implementation for your network.

Forums are useful when you need to reaffirm your design. Also if you have a set of requirements *and* understanding about your network.

With all due respect, I don't think you have that and I'm afraid to suggest anything here that ultimately may affect your network.
