Cisco CCNP / BCMSN Exam Tutorial: Changing The Active Router In HSRP
To move the BCMSN Test and make your CCNP certification, you’ve http://www.thefreedictionary.com/토토사이트 bought to find out HSRP within and out. Whilst the Procedure and standard instructions of HSRP are quite basic, there are a few significant details which have been quickly overlooked but are important in getting HSRP to operate the best way you want it to. Let’s Consider utilizing the priority command effectively on both equally the Examination and in creation networks.
A key price in the clearly show standby command would be the precedence. The default is one hundred, along with the router with the highest priority will be the Most important HSRP router. We’ll raise the default priority on R2 and see the effects. R3 is currently the Active router and R2 the standby, so let’s raise the precedence on R2 and find out what transpires.
R2(config)#interface ethernet0
R2(config-if)#standby five precedence 150
R2#show standby
Ethernet0 – Team 5
Neighborhood state is Standby, priority 150
Hellotime four sec, holdtime twelve sec
Following hello there sent in 0.896
Virtual IP handle is 172.twelve.23.ten configured
Active router is 172.twelve.23.3, priority a hundred expires in eight.072
Standby router is nearby
1 point out adjustments, final state adjust 00:14:24
R2 now has a higher priority, but R3 is still the Energetic router. R2 will likely not get above as being the HSRP primary till R3 goes down – Or perhaps the preempt alternative is configured on R2.
R2(config-if)#standby 5 precedence 150 preempt
1d11h: 토토사이트 %STANDBY-six-STATECHANGE: Ethernet0 Team 5 condition Standby -> Active
Area state is Lively, precedence one hundred fifty, may preempt
Upcoming hello there despatched in one.844
Lively router is nearby
Standby router is 172.12.23.3 expires in ten.204
Digital mac address is 0000.0c07.ac05
two point out modifications, last condition modify 00:00:thirteen
In just a couple seconds, a message appears the nearby point out has transformed from standby to active. Demonstrate standby confirms that R2, the nearby router, is now the active router – the main. R3 is currently the standby. Therefore if everyone informs you that you've got to have a router right down to change the Active router, they’re wrong – you just need to make use of the preempt solution over the standby priority command.
An additional vital Section of HSRP configurations is being aware of ways to change the MAC address with the virtual router, and also interface monitoring. We’ll evaluate All those capabilities in the next A part of my HSRP tutorial!
