Cisco CCNP / BCMSN Test Tutorial: Altering The Energetic Router In HSRP
To move the BCMSN Examination and generate your CCNP certification, you’ve received to be aware of HSRP inside and out. Even though the operation and basic instructions of HSRP are rather basic, there are a few important particulars which are conveniently missed but are crucial in finding HSRP to operate the way in which you want it to. Enable’s Consider utilizing the precedence command accurately on each the exam As well as in creation networks.
A critical worth from the present standby command may be the precedence. The default is 100, as well as the router with the very best precedence would be the Major HSRP router. We’ll https://www.washingtonpost.com/newssearch/?query=토토사이트 raise the default priority on R2 and find out the final results. R3 is now the Active router and R2 the standby, so Allow’s increase the priority on R2 and see what transpires.
R2(config-if)#standby 5 priority one hundred fifty
Ethernet0 – Team 5
Local point out is Standby, precedence 150
Hellotime 4 sec, holdtime twelve sec
Future howdy despatched in 0.896
Digital IP handle is 172.twelve.23.10 configured
Active router is 126.96.36.199, precedence a hundred expires in eight.072
Standby router is nearby
1 point out variations, very last state alter 00:14:24
R2 now has an increased precedence, but R3 is still the active router. R2 will never take around since the HSRP Key right until R3 goes down – Or even the preempt option is configured on R2.
R2(config-if)#standby 5 precedence one hundred fifty preempt
1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Group 5 point out Standby -> Active

In only a few seconds, a information seems the community condition has modified from standby to Energetic. Demonstrate standby confirms that R2, the local router, has become the active router – the key. R3 is currently the standby. So if anyone tells you you have to take a router all the way down to alter the Energetic router, they’re Incorrect – you only need to make use of the preempt selection about the standby priority command.
Another critical Component of HSRP configurations is recognizing the best way to change the MAC handle of your virtual router, along with interface monitoring. We’ll examine All those attributes in the subsequent Element of my HSRP tutorial!
