Cisco CCNP / BCMSN Test Tutorial: Shifting The Active Router In HSRP
To go the BCMSN exam and receive your CCNP certification, you’ve bought to understand HSRP within and out. Whilst the Procedure and fundamental instructions of HSRP are pretty very simple, there are some critical facts that happen to be easily disregarded but are crucial in receiving HSRP to work just how you wish it to. Allow’s Look into using the precedence command effectively on both equally the exam As well as in output networks.
A crucial worth in the present standby command is the priority. 먹튀검증사이트 The default is a hundred, and also the router with the very best precedence will be the Most important HSRP router. We’ll elevate the default priority on R2 and find out the final results. R3 is at present the Active router and R2 the standby, so let’s increase the priority on R2 and find out what comes about.
R2(config)#interface ethernet0
R2(config-if)#standby five priority one hundred fifty
R2#present standby
Ethernet0 – Group five
Regional point out is Standby, priority a hundred and fifty
Hellotime 4 sec, holdtime 12 sec

Digital IP handle is 172.12.23.10 configured
Active router is 172.12.23.three, precedence one hundred expires in 8.072
Standby router http://www.bbc.co.uk/search?q=토토사이트 is nearby
one state alterations, past condition modify 00:14:24
R2 now has a better priority, but R3 is still the Lively router. R2 will likely not acquire in excess of given that the HSRP Most important right until R3 goes down – Or maybe the preempt selection is configured on R2.
R2(config-if)#standby five priority 150 preempt
1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Group 5 state Standby -> Active
Area condition is Active, priority a hundred and fifty, may preempt

In just a few seconds, a information appears that the community state has changed from standby to Lively.
