Cisco CCNP / BCMSN Examination Tutorial: Transforming The Energetic Router In HSRP
To pass the BCMSN exam and gain your CCNP certification, you’ve received to learn HSRP inside and out. Even though the operation and basic commands of HSRP are pretty simple, there are many crucial specifics which can be very easily ignored but are important in getting HSRP to work how you'd like it to. Enable’s Consider utilizing the precedence command accurately on each the Test As well as in creation networks.
A important benefit within the exhibit standby command is definitely the priority. The default is 100, as well as the router with the best precedence would be the Main HSRP router. We’ll elevate the default priority on R2 and see the results. R3 is at this time the Energetic router and R2 the standby, so Allow’s elevate the priority on R2 and find out what comes about.
R2(config)#interface ethernet0
R2(config-if)#standby 5 priority a hundred and fifty
R2#display standby
Ethernet0 – Team five
Area point out is Standby, priority a hundred and fifty
Hellotime four sec, holdtime twelve sec
Following hello despatched in 0.896
Virtual IP deal with is 172.12.23.ten configured
Active router is 172.twelve.23.3, precedence a hundred expires in 8.072
Standby router is nearby
1 point out alterations, very last point out modify 00:fourteen:24
R2 now has the next priority, but R3 remains to be the Lively router. R2 will not likely get about as being the HSRP Most important until finally R3 goes down – Or perhaps the preempt choice is configured on R2.
R2(config-if)#standby five precedence a hundred and fifty preempt
1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Group five point out Standby -> Active
Neighborhood condition is Active, precedence a hundred and fifty, may perhaps preempt
Following hi there sent in 1.844
Energetic router is area
Standby router is 먹튀검증 172.12.23.3 expires in ten.204
Virtual mac address is 0000.0c07.ac05
2 condition alterations, last condition adjust 00:00:thirteen
In just a few seconds, a information seems the regional point out has transformed from standby to Lively. Exhibit standby confirms that R2, the local router, is now the Energetic router – the first. R3 has become the standby. So if any one informs you that you've got to have a router all the way down to alter the Energetic router, they’re Completely wrong – you simply have to utilize the preempt option to the standby priority command.
