HSRP With 1 Circuit

Is it possible to have a connection from 1 T1 card (1 circuit) to 2 router serial interfaces for use with HSRP?

Re: HSRP With 1 Circuit

If i understand correctly each router has available interfaces?, You can configure HSRP on each router and configure them to track the T1. Connect the T1 to one router, and the other will go into standby state. When one router fails , you will have to physically reconnect the T1 (with identical config to the other router) to the backup router so it goes active.

Interesting. What happen if you have a circuit outage? Router don't have moving parts, so they don't usually fail. If you are going to invest in 2 routers, I suggest you use ISDN for backup. The cost should nominal if your T1 is reliable. ISDN billing is base on usage.
