Cisco CCNP / BCMSN Test Tutorial: Shifting The Active Router In HSRP
To move the BCMSN Test and gain your CCNP certification, you’ve obtained to be aware of HSRP inside and out. Even though the Procedure and essential commands of HSRP are quite basic, usually there are some significant information which are conveniently overlooked but are essential in obtaining HSRP to http://edition.cnn.com/search/?text=먹튀검증 operate the way in which you would like it to. Enable’s Look into utilizing the precedence command properly on both of those the exam As well as in creation networks.
A vital worth inside the demonstrate standby command is definitely the priority. The default is a hundred, as well as router with the very best priority would be the primary HSRP router. We’ll raise the default precedence on R2 and find out the effects. R3 is now the Lively router and R2 the standby, so Allow’s increase the priority on R2 and see what takes place.
R2(config)#interface ethernet0
R2(config-if)#standby 5 precedence a hundred and fifty
R2#display standby
Ethernet0 – Team five
Nearby condition is Standby, precedence one hundred fifty
Hellotime four sec, holdtime twelve sec
Up coming howdy despatched in 0.896
Virtual IP tackle is 172.12.23.ten configured
Lively router is 172.12.23.three, priority a hundred expires in eight.072
Standby router is local
one condition variations, very last state alter 00:fourteen:24
R2 now has a higher priority, but R3 remains the active router. R2 will not take more than as the HSRP Key until eventually R3 goes down – Or perhaps the preempt choice is configured on R2.
R2(config-if)#standby 5 priority one hundred fifty preempt
1d11h: %STANDBY-six-STATECHANGE: Ethernet0 Team five condition Standby -> Lively
Regional state is Active, precedence 150, could preempt
Future hello despatched in one.844
Active router is nearby
Standby router is 172.twelve.23.3 expires in 10.204
Virtual mac address is 0000.0c07.ac05
2 point out modifications, final condition adjust 00:00:13
In only a few seconds, a concept seems the local condition has altered from standby to active. Clearly show standby confirms that R2, the neighborhood router, has become the Lively router – the first. R3 is now the standby. Therefore if any individual tells you that you have to take a router down to alter the Energetic router, they’re Mistaken – you merely have to use the preempt solution within the standby priority command.
