Cisco CCNP / BCMSN Test Tutorial: Changing The Active Router In HSRP
To move the BCMSN exam and earn your CCNP certification, you’ve obtained to grasp HSRP within and out. While the Procedure and basic commands of HSRP are quite simple, there are a few crucial details which can be very easily ignored but are important in getting HSRP to operate just how you would like 먹튀검증 it to. Enable’s Have a look at using the precedence command appropriately on the two the Test As well as in output networks.
A vital price while in the display standby command may be the precedence. The http://edition.cnn.com/search/?text=먹튀검증 default is 100, along with the router with the best precedence would be the primary HSRP router. We’ll increase the default priority on R2 and see the results. R3 is currently the Active router and R2 the standby, so Enable’s raise the precedence on R2 and see what occurs.
R2(config)#interface ethernet0
R2(config-if)#standby five precedence 150
R2#display standby
Ethernet0 – Team five
Community condition is Standby, priority 150
Hellotime four sec, holdtime 12 sec

Active router is 172.twelve.23.3, priority 100 expires in 8.072
Standby router is local

R2 now has a better precedence, but R3 continues to be the active router. R2 will not likely get about as the HSRP Main until finally R3 goes down – Or maybe the preempt option is configured on R2.
R2(config-if)#standby 5 priority 150 preempt
1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Group 5 state Standby -> Lively
Community condition is Energetic, precedence a hundred and fifty, may preempt

In only a few seconds, a message seems the neighborhood point out has adjusted from standby to Energetic. Exhibit standby confirms that R2, the neighborhood router, is now the active router – the main. R3 is currently the standby. So if everyone lets you know that you've to have a router all the way down to change the Energetic router, they’re Completely wrong – you merely must use the preempt possibility to the standby precedence command.
