Trying to work out the best method for a small problem we have.
There is a single 2800 series router with 2 ethernet interfaces, each one goes to a 6500 series switch.
The router has a bunch of isdn's attached for our FOIP environment.
What we want is to provide redundancy in that if one switch fails our FOIP environment will keep working.
I cannot use HSRP as there is only one router with 2 interfaces so what else can I use ?
