Say there are two Router R1 and R2 configure with HSRP. R1 is active and R2 is standby. R1 has the command "standby 1 preempt" configure on it. Both R1 and R2 configure with "standby 1 timers 5 10.
1) Now there is a network failure on R1.
I know R2 will take over as active. How long will R2 take over as active from R1?
is it depend on holdtime which is 10 sec in this case?
2) If R1 has recover, will R1 regain as active router from R2 straignt away? Must R1 have to wait to regain its active status? I heard in real world, R2 would still be active until a reboot on R2 then R1 will regain his active status.
