Cisco CCNP / BCMSN Examination Tutorial: Transforming The Energetic Router In HSRP
To move the BCMSN Examination and earn your CCNP certification, you’ve obtained to find out HSRP within and out. Whilst the Procedure and fundamental commands of HSRP are rather simple, there are many important aspects that are simply neglected but are essential in acquiring HSRP to operate just how you want it to. Permit’s Have a look at using the priority command appropriately 메이저사이트 on both equally the exam and in manufacturing networks.
A crucial worth within the exhibit standby command is definitely the precedence. The default is one hundred, along with the router with the very best precedence would be the Major HSRP router. We’ll elevate the default precedence on R2 and find out the outcomes. R3 is presently the Energetic router and R2 the standby, so let’s elevate the priority on R2 and https://www.washingtonpost.com/newssearch/?query=토토사이트 see what transpires.
R2(config)#interface ethernet0
R2(config-if)#standby five precedence one hundred fifty
R2#present standby
Ethernet0 – Group 5
Community point out is Standby, priority a hundred and fifty
Hellotime 4 sec, holdtime twelve sec
Next good day sent in 0.896
Virtual IP handle is 172.12.23.ten configured
Lively router is 172.twelve.23.3, precedence a hundred expires in eight.072
Standby router is neighborhood
1 state changes, past condition change 00:14:24
R2 now has the next precedence, but R3 is still the Energetic router. R2 won't take above as being the HSRP primary until finally R3 goes down – Or perhaps the preempt alternative is configured on R2.
R2(config-if)#standby 5 precedence one hundred fifty preempt
1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Team 5 point out Standby -> Energetic
Neighborhood point out is Energetic, priority one hundred fifty, may well preempt
Future hi there despatched in one.844
Energetic router is nearby
Standby router is 172.12.23.three expires in 10.204
Virtual mac handle is 0000.0c07.ac05
2 point out changes, final state transform 00:00:thirteen
In just some seconds, a concept appears which the community state has transformed from standby to Energetic. Clearly show standby confirms that R2, the regional router, has become the Lively router – the main. R3 is now the standby. So if any person tells you that you've to take a router down to change the Energetic router, they’re Incorrect – you only must use the preempt choice on the standby precedence command.
One more vital A part of HSRP configurations is understanding the way to change the MAC handle from the virtual router, along with interface tracking. We’ll take a look at All those functions in the subsequent Component of my HSRP tutorial!
