Cisco CCNP / BCMSN Test Tutorial: Altering The Active Router In HSRP
To pass the BCMSN Examination and generate your CCNP certification, you’ve obtained to grasp HSRP inside of and out. Although the Procedure and fundamental instructions of HSRP are really uncomplicated, there are a https://en.wikipedia.org/wiki/?search=먹튀검증 few critical details which can be easily overlooked but are essential in having HSRP to work the way you'd like it to. Permit’s Examine using the precedence command properly on both the Examination As well as in generation networks.
A essential price inside the clearly show standby command may be the priority. The default is a hundred, and also the router with the very best precedence will be the Major HSRP router. We’ll increase the default priority on R2 and see the results. R3 is now the Energetic router and R2 the standby, so Permit’s increase the priority on R2 and see what comes about.
R2(config)#interface ethernet0
R2(config-if)#standby 5 precedence a hundred and fifty
R2#clearly show standby
Ethernet0 – Group 5
Local condition is Standby, precedence one hundred fifty
Hellotime 4 sec, holdtime 12 sec
Up coming hi there sent in 0.896
Digital IP handle is 172.12.23.10 configured
Energetic router is 172.twelve.23.three, precedence a hundred expires in eight.072
Standby router is local
one state alterations, past condition modify 00:14:24
R2 now has the next priority, but R3 continues to be the Lively router. R2 won't consider over because the HSRP Main till R3 goes down – Or maybe the preempt selection is configured on R2.
R2(config-if)#standby five precedence a hundred and fifty preempt
1d11h: %STANDBY-six-STATECHANGE: Ethernet0 Team five state Standby -> Active
Community state is Active, priority a hundred and fifty, might preempt
Up coming howdy despatched in one.844
Lively router is local
Standby router is 172.twelve.23.three expires in ten.204
Digital mac handle is 0000.0c07.ac05
2 condition changes, last condition modify 00:00:thirteen
In just a couple seconds, a concept seems that the area condition has changed from standby to active. Show standby confirms that R2, the nearby router, is currently the Energetic router – the primary. R3 is now the standby. Therefore if anyone informs you that you've got to take a router down to change the Lively router, they’re Erroneous – you merely need 먹튀사이트 to utilize the preempt solution around the standby priority command.
An additional important Portion of HSRP configurations is recognizing the way to alter the MAC deal with from the virtual router, and also interface tracking. We’ll check out Those people features in the following A part of my HSRP tutorial!
