Cisco CCNP / BCMSN Exam Tutorial: Shifting The Active Router In HSRP
To move the BCMSN Test and gain your CCNP certification, you’ve acquired to be aware of HSRP inside of and out. Although the operation and simple instructions of HSRP are quite uncomplicated, there are many important details that are easily missed but are very important in acquiring HSRP to operate the way 먹튀검증 you need it to. Permit’s take a look at utilizing the precedence command appropriately on each the Test and in generation networks.
A important benefit during the exhibit standby command is the priority. The default is one hundred, as well as router with the highest precedence will be the Main HSRP router. We’ll raise the default precedence on R2 and see the outcome. R3 is at the moment the Energetic router and R2 the standby, so Permit’s raise the precedence on R2 and see what occurs.
R2(config)#interface ethernet0
R2(config-if)#standby five priority 150
R2#present standby
Ethernet0 – Group five
Local state is Standby, precedence 150
Hellotime four sec, holdtime twelve sec
Upcoming hi there sent in 0.896
Digital IP tackle is 172.12.23.ten configured
Active router is 172.12.23.three, priority one hundred expires in 8.072
Standby router is nearby
1 point out improvements, last state change 00:14:24
R2 now has a better priority, but R3 continues to be http://edition.cnn.com/search/?text=먹튀검증 the Lively router. R2 will likely not get over as the HSRP Major until eventually R3 goes down – OR 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 -> Lively
Area state is Active, priority a hundred and fifty, might preempt
Future hi sent in 1.844
Energetic router is area
Standby router is 172.twelve.23.three expires in 10.204
Digital mac handle is 0000.0c07.ac05
two point out changes, very last state transform 00:00:thirteen
In just a few seconds, a information seems which the area condition has changed from standby to active. Demonstrate standby confirms that R2, the neighborhood router, is now the active router – the main. R3 is now the standby. So if everyone lets you know that you've got to have a router down to change the Active router, they’re Completely wrong – you only have to make use of the preempt alternative to the standby priority command.
A different critical Element of HSRP configurations is realizing how you can change the MAC handle from the virtual router, and also interface monitoring. We’ll examine People functions in the next Portion of my HSRP tutorial!
