Cisco CCNP / BCMSN Exam Tutorial: Shifting The Energetic Router In HSRP
To move the BCMSN Examination and earn your CCNP certification, you’ve got to know HSRP inside of and out. Even though the operation and primary commands of HSRP are rather very simple, there are numerous significant facts which can be conveniently missed but are critical in acquiring HSRP to work the best way you need it to. Enable’s Check out utilizing the precedence command accurately on both equally the Examination As well as in manufacturing networks.
A critical worth in the present standby command is the priority. The default is one hundred, along 안전놀이터 with the router with the best precedence would be the Principal HSRP router. We’ll elevate the default priority on R2 and find out the results. R3 is at this time the Energetic router and R2 the standby, so Allow’s increase the priority on R2 and see what happens.
R2(config)#interface ethernet0
R2(config-if)#standby 5 priority 150
R2#clearly show standby
Ethernet0 – Group 5
Local condition is Standby, priority a hundred and fifty
Hellotime 4 sec, holdtime 12 sec
Up coming hi sent in 0.896
Virtual IP tackle is 172.12.23.10 configured
Lively router is 172.twelve.23.three, precedence 100 expires in eight.072
Standby router is local
one point out modifications, final state change 00:fourteen:24
R2 now has a higher priority, but R3 is still the Lively router. R2 won't take more than as being the HSRP Main right until R3 goes down – Or maybe the preempt alternative is configured on R2.

In just some seconds, a information seems which the local condition has changed from standby to Lively. Clearly show standby confirms that R2, the nearby router, is currently the Lively router – the key. R3 has become the standby. Therefore if anybody informs you that you've got to take a router down to change the Active router, they’re Incorrect – you only really have to utilize the preempt option to the standby priority command.
A different crucial A part of HSRP configurations is being aware of the way to change the MAC deal with of the virtual router, and also interface monitoring. We’ll evaluate Those people capabilities in the next A part of my HSRP tutorial!
