Though the Procedure and standard instructions of HSRP are really straightforward, there are several crucial details that are effortlessly overlooked but are important in having HSRP to work the way you'd like it to. Let’s take a look at using the priority command effectively on the two the exam and in production networks.
A vital value from the clearly show standby command is the precedence. The default is 100, plus the router with the very best precedence will be the Most important HSRP router. We’ll raise the default precedence on R2 and find out the final results. R3 is at this time the Active router and R2 the standby, so Enable’s raise the precedence on R2 and see what happens.
R2(config-if)#standby five priority a hundred and fifty
Ethernet0 – Group five
Nearby condition is Standby, priority one hundred fifty
Hellotime four sec, holdtime twelve sec
Subsequent hello there sent in 0.896
Virtual IP deal with is 172.twelve.23.ten configured
Energetic router is 172.12.23.three, priority a hundred expires in 8.072
Standby router is regional
1 state modifications, previous state alter 00:fourteen:24
R2 now has a higher priority, but R3 remains to be the active router. R2 is not going to acquire around because the HSRP primary until R3 goes down – Or even the preempt selection is configured on R2.
R2(config-if)#standby 5 priority 150 preempt
1d11h: %STANDBY-six-STATECHANGE: Ethernet0 Group 5 state Standby -> Energetic
Community condition is Lively, priority a hundred and fifty, could preempt
Upcoming hi sent in 1.844
Lively router is nearby
Standby router is 172.12.23.three expires in 10.204
Digital mac deal with is 0000.0c07.ac05
