Cisco CCNP / BCMSN Examination Tutorial: Transforming The Energetic Router In HSRP
To pass the BCMSN Test and make your CCNP certification, you’ve bought to learn HSRP inside and out. When the Procedure and standard instructions of HSRP are pretty straightforward, usually there are some important facts which can be easily neglected but are crucial in getting HSRP to operate the best way you want it to. Permit’s Consider utilizing the precedence command properly on both of those the Examination As well as in manufacturing networks.
A essential price within the demonstrate standby command could be the precedence. The default is a hundred, along with the router with the very best priority will be the primary HSRP router. We’ll increase the default priority on R2 and see the effects. R3 is now the Energetic router and R2 the standby, so Allow’s elevate the precedence on R2 and find out what comes about.
R2(config)#interface ethernet0
R2(config-if)#standby five precedence a hundred and fifty
R2#clearly show standby
Ethernet0 – Team 5
Neighborhood point out is Standby, priority one hundred fifty
Hellotime four sec, holdtime twelve sec
Subsequent hello there sent in 0.896
Digital IP deal with is 172.twelve.23.ten configured
Lively router is 172.12.23.3, precedence a hundred expires in eight.072
Standby router http://edition.cnn.com/search/?text=먹튀검증 is regional
one condition adjustments, last state modify 00:fourteen:24
R2 now has an increased precedence, but R3 remains the active router. R2 will not likely choose over as the HSRP Major until R3 goes down – Or even the preempt solution is configured on R2.
R2(config-if)#standby 5 precedence 150 preempt
1d11h: %STANDBY-six-STATECHANGE: Ethernet0 Team five state Standby -> Lively
Local condition is Active, precedence a hundred and fifty, may perhaps preempt
Up coming hello there sent in 1.844
Lively router is regional
Standby router is 172.12.23.three expires in ten.204
Virtual mac deal with is 0000.0c07.ac05
two point out variations, past point out change 00:00:13
In only a few seconds, a message seems which the regional condition has transformed from standby to active. Clearly show standby confirms that R2, the regional router, has become the active router – the principal. R3 is now the standby. So if everyone 먹튀사이트 lets you know that you've to have a router down to change the Lively router, they’re Mistaken – you simply need to use the preempt alternative around the standby priority command.
An additional vital Portion of HSRP configurations is realizing how to change the MAC tackle in the Digital router, as well as interface tracking. We’ll have a look at All those characteristics in the subsequent part of my HSRP tutorial!
