Cisco CCNP / BCMSN Exam Tutorial: Transforming The Active Router In HSRP
To pass the BCMSN Examination and generate your CCNP certification, you’ve obtained to find out HSRP inside and out. Though the operation and standard commands of HSRP are pretty simple, there are some essential information which can be easily disregarded but are important in getting HSRP to work just how you desire it to. Allow’s Consider utilizing the precedence command the right way on equally the Examination As well as in manufacturing networks.
A critical benefit from the clearly show standby command could be the precedence. The default is a hundred, along with the router with the best precedence would be the Main HSRP router. We’ll increase the default precedence on R2 먹튀검증사이트 and find out the final results. R3 is currently the Energetic router and R2 the standby, so let’s raise the priority on R2 and find out what comes about.
R2(config)#interface ethernet0
R2(config-if)#standby 5 precedence a hundred and fifty
R2#exhibit standby
Ethernet0 – Group 5
Area condition is Standby, priority one hundred fifty
Hellotime four sec, holdtime 12 sec
Subsequent howdy despatched in 0.896
Digital IP deal with is 172.12.23.ten configured
Active router is 172.twelve.23.3, priority 100 expires in 8.072
Standby router is area
1 point out changes, last condition alter 00:14:24
R2 now has a higher priority, but R3 is still the Lively router. R2 will likely not choose above as being the HSRP Major until finally R3 goes down – Or maybe the preempt selection is configured on R2.
R2(config-if)#standby 5 priority 150 preempt
1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Team five point out Standby -> Energetic
Nearby http://edition.cnn.com/search/?text=토토사이트 state is Lively, precedence a hundred and fifty, could preempt
Next hello sent in 1.844
Lively router is area
Standby router is 172.12.23.3 expires in 10.204
Virtual mac tackle is 0000.0c07.ac05
two condition adjustments, final condition alter 00:00:thirteen
In only a few seconds, a concept appears the area state has modified from standby to active. Clearly show standby confirms that R2, the area router, has become the Lively router – the principal. R3 is currently the standby. Therefore if any individual informs you that you've to take a router down to change the Lively router, they’re Incorrect – you just need to use the preempt selection to the standby priority command.
An additional important Component of HSRP configurations is recognizing ways to change the MAC deal with from the virtual router, as well as interface monitoring. We’ll evaluate All those features in the subsequent A part of my HSRP tutorial!
