Cisco CCNP / BCMSN Examination Tutorial: Transforming The Active Router In HSRP
To move the BCMSN exam and earn your CCNP certification, you’ve acquired to find out HSRP inside and out. While the operation and standard commands of HSRP are quite simple, there are some significant information that happen to be quickly missed but are vital in finding HSRP to work the best way you'd like it to. Enable’s Examine using the priority command the right way on each the exam As well as in production networks.
A critical value during the clearly show standby command would be the priority. The default is one hundred, plus the router with the best precedence will be the Most important HSRP router. We’ll raise the default priority on R2 and find out the outcome. R3 is at present the Energetic router and R2 the standby, so Enable’s increase the priority on R2 and see what comes about.
R2(config)#interface ethernet0
R2(config-if)#standby five priority 150
R2#exhibit standby
Ethernet0 – Group 5
Nearby point out is Standby, priority one hundred fifty
Hellotime 4 sec, holdtime 12 sec
Future good day despatched in 0.896
Virtual IP tackle is 172.12.23.10 configured
Lively router is 172.twelve.23.3, precedence one hundred expires in eight.072
Standby router is local
one condition improvements, previous state improve 00:fourteen:24
R2 now has a greater precedence, but R3 remains to be the Energetic router. R2 is not going to take in excess of since the HSRP Key until R3 goes down – Or even the preempt possibility is configured on R2.
R2(config-if)#standby five priority a hundred and fifty preempt
1d11h: %STANDBY-six-STATECHANGE: Ethernet0 Group 5 state Standby -> Lively
Nearby state is Lively, priority a hundred and fifty, may perhaps preempt
