Greg,
An easier thing to do might be to create 2 hot standby
groups on the 7206's. Then, based on traffic, you
configure some devices to use standby group 1 as the
default and the others to use standby group 2 as the
default. If either one goes down, then all traffic
will use the remaining one.
Sample config.
hostname RouterA
!
interface ethernet 0
ip address 1.0.0.1 255.0.0.0
standby 1 ip 1.0.0.3
standby 1 priority 110
standby 1 preempt
standby 2 ip 1.0.0.4
standby 2 preempt
hostname RouterB
!
interface ethernet 0
ip address 1.0.0.2 255.0.0.0
standby 1 ip 1.0.0.3
standby 1 preempt
standby 2 ip 1.0.0.4
standby 2 priority 110
standby 2 preempt
anyway,
just a thought.
