You could modify your Hello and hold times and that may increase the
time it takes before a standby will assume the active role.

Hello,
We've got a 2501 frame router and a 1603 ISDN backup
router at a branch office, configured as HSRP.

One more comment, though. Tracking an additional interface may not meet his
needs since he said he was hoping for a router failover in the event "a
link goes down somewhere down the line." For that kind of behavior, you
would need a routing protocol. Routing protocols track failures in routes,
Now, this is the kind of situation the various design certs should test on!

Regarding your actual question, have you considered a Layer-8 solution?
Depending on who you talk to, Layer 8 deals with money, politics, planning,
etc. My thinking is that you should select a provider that gives
Can't this be treated as two separate issues - the HSRP and the routing.
If BGP peers are set up effectively in a triangle between remote office and
central site over the two links, they should be able to run independantly of
HSRP.
If the active router receives a packet but BGP tells it that the
I've done this configuration before. It's relatively painless.
If you're using Cisco-to-Cisco equipment, you can create GRE tunnels at the
endpoints and encrypt them. On the far-end, you'll have 2 tunnel
interfaces, one to each central site router.
If you run an IGP over the tunnels, then

HSRP works at the LAN interface (or sub-interface) level.
The purpose of HSRP is to provide default gateway in the event of router
failure.
Each router has an IP address on an interface and there is a virtual router
(IP address) created between
the two routers, where one is active, the other is

The first router would not necassarily have to lose connectivity to the
second router in order to fail over. HSRP can be configured to track an
additional interface. For example you could track the link to the ISP. If
that link goes down the router decrements its priority (default decrease is
You can have both of these routers running in HSRP. However, you have to
enable "HSRP Interface Tracking" so that the line will fail-over to the
second router. The command is in this format:
Router(config-if)# standby group-number track type number interface-priority

Cool. I didn't know about this interface tracking feature. It sounds like
it could meet his needs. Thanks,

HSRP operates at the interface level.
The benefit HSRP provides is this: Let's say you have a number of Workstations
or Servers on a LAN segment where more than one router exist.
I can see what you are trying to accomplish on this.
You want it, so that if and when one link (WAN
interface) on the router that connects to the ISP goes
down for the other router to pick up HSRP tasks. Look
into the track command. HSRP has an associated
priority to it, the router with the
