Cisco CCNP / BCMSN Test Tutorial: Changing The Active Router In HSRP
To go the BCMSN Test and receive your CCNP certification, you’ve obtained to learn HSRP inside of and out. While the operation and primary commands of HSRP are quite uncomplicated, there are numerous critical specifics which have been quickly missed but are critical in acquiring HSRP to work just how you would like it to. Enable’s Check out using the priority command properly on each the exam As well as in creation networks.
A important worth from the demonstrate standby command would be the priority. The default is a hundred, and also the router with the best priority will be the Major HSRP router. We’ll elevate the default precedence on R2 and see the outcomes. R3 is at the moment the Energetic router and R2 the standby, so Allow’s raise the precedence on R2 and find out what transpires.
R2(config)#interface ethernet0
R2(config-if)#standby 5 precedence a hundred and fifty
R2#present standby
Ethernet0 – Group five
Area state is Standby, precedence one hundred fifty
Hellotime four sec, holdtime 12 sec
Up coming hello there despatched in 0.896
Virtual IP tackle is 172.12.23.ten configured

Standby router is area

R2 now has an increased precedence, but R3 remains the Lively router. R2 will never acquire in excess of given that the HSRP Main right up until R3 goes down – Or 먹튀검증업체 maybe the preempt option is configured on R2.
R2(config-if)#standby 5 priority one hundred fifty preempt
1d11h: %STANDBY-six-STATECHANGE: Ethernet0 Group five point out Standby -> Active
Area condition is Active, priority a hundred and fifty, may preempt
Next hi sent in 1.844
Lively router is community
Standby router is 172.12.23.three expires in ten.204
Virtual mac address is 0000.0c07.ac05
two state modifications, last point out transform 00:00:13
In just some seconds, a information appears which the community point out has transformed from standby to active. Exhibit standby confirms that R2, the nearby router, has become the active router – the main. R3 has become the standby. So if any individual informs you that you have to have a router all the way down to alter the Active router, they’re Erroneous – you only need to use the preempt solution about the standby priority command.
One more important part of HSRP configurations is recognizing how to change the MAC tackle of your virtual router, and interface tracking. We’ll check out Individuals options in another part of my HSRP tutorial!
