You can simply use the standby track where a tracked interface is checked by
hsrp... i.e.
R1/R2
R1
Int f0/0
Standby 1 ip 1.1.1.10
Standby 1 track int s0/0 20
Standby 1 priority 110
ip route 0.0.0.0 0.0.0.0 <to bb1>
R2
Int f0/0
Standby 1 ip 1.1.1.10
ip route 0.0.0.0 0.0.0.0 <to bb2>
(some static route to router 3)
ip route 0.0.0.0 0.0.0.0 3.3.3.3 254
R3
Optionally, if R3 has l2 adjacency to the users; the allow r3 to be a 3rd
hsrp listener
int r3
standby 1 ip 1.1.1.10
standby 1 priority 50
in a real world setting I often weight standby priorities to tracked
objects; such as routes, and interface line-protocols, etc.
i.e.
standby 1 track 1 20
track 1 ip route 0.0.0.0/0 reachability

Hi Folks,
I am running a test lab as follows:
R1------------BB1
|
|
|
|
|
|
|
R2------------BB2
|
|
|
|
|
|
R3
R1 is connected to BB1
R1 is connected R2
R2 is connected to BB2
R2 is connected R3
R1 and R2 is running HSRP. If R1 loses the link to BB1 or R2 loses the link
to BB2 the other router servers the users. If R1 loses BB1 and R2 loses BB2,
R2 must route traffic through R3. I am wondering what would be the best
solution for this.
Any pointers are welcome.
Regards,
Shine
