Cisco CCNP / BCMSN Exam Tutorial: Transforming The Energetic Router In https://en.search.wordpress.com/?src=organic&q=먹튀검증 HSRP
To move the BCMSN Examination and receive your CCNP certification, you’ve received to understand HSRP inside of and out. Whilst the Procedure and standard instructions of HSRP are rather simple, there are several significant aspects which check here have been effortlessly missed but are crucial in getting HSRP to work the way in which you need it to. Allow’s Check out using the precedence command properly on both of those the exam As well as in production networks.
A critical benefit inside the demonstrate standby command is definitely the priority. The default is one hundred, and also the router with the best priority will be the Most important HSRP router. We’ll raise the default priority on R2 and see the results. R3 is presently the Active router and R2 the standby, so let’s elevate the precedence on R2 and find out what occurs.
R2(config)#interface ethernet0
R2(config-if)#standby 5 precedence 150
R2#show standby
Ethernet0 – Team 5
Local point out is Standby, priority 150
Hellotime four sec, holdtime 12 sec
Following howdy sent in 0.896
Digital IP address is 172.twelve.23.10 configured
Energetic router is 172.twelve.23.three, priority one hundred expires in eight.072
Standby router is nearby
1 point out improvements, last point out adjust 00:14:24
R2 now has a better priority, but R3 remains to be the Lively router. R2 will not just take around as being the HSRP Major until R3 goes down – Or maybe the preempt selection is configured on R2.
R2(config-if)#standby 5 precedence a hundred and fifty preempt
1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Group five condition Standby -> Active
Nearby condition is Energetic, precedence a hundred and fifty, could preempt
Following hello there sent in one.844
Active router is nearby
Standby router is 172.twelve.23.3 expires in 10.204
Virtual mac tackle is 0000.0c07.ac05
2 state variations, previous point out modify 00:00:thirteen
In just a couple seconds, a information seems which the community point out has transformed from standby to active. Present standby confirms that R2, the neighborhood router, has become the active router – the first. R3 is now the standby. Therefore if any individual tells you that you have to have a router right down to alter the Lively router, they’re Mistaken – you only really need to make use of the preempt alternative on the standby precedence command.
Yet another very important Section of HSRP configurations is recognizing tips on how to alter the MAC handle with the Digital router, as well as interface tracking. We’ll examine Those people capabilities in the subsequent Section of my HSRP tutorial!
