Cisco CCNP / BCMSN Exam Tutorial: Switching The Lively Router In HSRP
To move the BCMSN exam and earn your CCNP certification, you’ve obtained to find out HSRP inside and out. Although the operation and basic instructions of HSRP are fairly very simple, there are some vital particulars that happen to be simply overlooked but are vital in acquiring 안전공원 HSRP to operate just how you wish it to. Enable’s take a look at using the precedence command accurately on both of those the Examination and in output networks.
A important benefit inside the exhibit standby command could be the precedence. The default is 100, plus the router with the very best precedence will be the Most important HSRP router. We’ll raise https://www.washingtonpost.com/newssearch/?query=토토사이트 the default precedence on R2 and find out the results. R3 is presently the Lively router and R2 the standby, so let’s elevate the priority on R2 and see what comes about.
R2(config)#interface ethernet0
R2(config-if)#standby five precedence 150
R2#demonstrate standby
Ethernet0 – Group 5
Community state is Standby, precedence one hundred fifty
Hellotime 4 sec, holdtime twelve sec
Next howdy sent in 0.896
Digital IP tackle is 172.twelve.23.10 configured
Active router is 172.12.23.3, precedence a hundred expires in 8.072
Standby router is neighborhood
one condition changes, previous condition improve 00:fourteen:24
R2 now has a higher precedence, but R3 is still the Energetic router. R2 is not going to take in excess of as being the HSRP Main right until R3 goes down – Or even the preempt possibility is configured on R2.
R2(config-if)#standby five precedence one hundred fifty preempt
1d11h: %STANDBY-six-STATECHANGE: Ethernet0 Team five point out Standby -> Energetic
Neighborhood condition is Active, precedence one hundred fifty, may preempt
Upcoming howdy sent in 1.844
Active router is nearby
Standby router is 172.12.23.three expires in ten.204
Digital mac deal with is 0000.0c07.ac05
2 state variations, past condition change 00:00:thirteen
In just a couple seconds, a information seems the nearby point out has changed from standby to Lively. Demonstrate standby confirms that R2, the nearby router, is currently the Energetic router – the key. R3 is currently the standby. So if anybody tells you that you have to take a router down to alter the Active router, they’re Mistaken – you merely really have to utilize the preempt alternative about the standby priority command.
A further very important Element of HSRP configurations is realizing the way to change the MAC deal with on the virtual router, as well as interface tracking. We’ll look at These capabilities in the next Portion of my HSRP tutorial!
