Question : Problem: HSRP

I have two ISPs, 1 is the primary and 2 is the back up.
I have two routers, one for each ISP, A connects to 1 and B connects to 2.

Router C chooses which router (A or B) to send the traffic to.  Right now, if ISP 1 goes down, i manually add a route to send traffic to router B, to use ISP 2.
 
Router B also tells router C how to get to Network N2 using EIGRP.

I would like to configure HSRP on routers A and B.

If i configure router A as the primary, and B as the standby, will router B still advertise routes to network N2?

That is, router A has the IP address x.x.x.2 and route B has the ip address x.x.x.3 and the standby address will be x.x.x.1.  Router C knows to send traffic for Network 2 (N2) to x.x.x.2.  If i configure the interface x.x.x.2 for HSRP, will it stop advertising routes to router C?

Here is a 'picture' of my network:

1      2      
|        |
A      B
  \    /   \
   \  /          N2
    C
     |
     |
    N1

Answer : Problem: HSRP

You have a couple options, if your interface goes down when you lose connection then the above should work just fine. If not you can use SLA monitoring to track the reliability.

Heres a sample config
!
ip sla monitor 1
 type echo protocol ipIcmpEcho 4.2.2.2        (A DNS server I remember, can be anything)
 timeout 5
 frequency 5
ip sla monitor schedule 1 life forever start-time now
!
track 1 rtr 1
!
!
router eigrp 100
 redistribute static
 network 10.0.0.0
 no auto-summary
!
ip route 0.0.0.0 0.0.0.0 FastEthernet0/1 track 1
