Cisco CCNP / BCMSN Examination Tutorial: Transforming The Energetic Router In HSRP
To go the BCMSN Test and earn your CCNP certification, you’ve bought to know HSRP inside of and out. Although the Procedure and fundamental commands of HSRP are rather very simple, there are some significant details that happen to be simply neglected but are vital in receiving HSRP to work the way in which you would like it to. Permit’s Have a look at utilizing the priority command the right way on equally the Test and in creation networks.
A essential worth inside the exhibit standby command could be the precedence. The default is one hundred, and also the router with the highest precedence will be the primary HSRP router. We’ll increase the default priority on R2 and find out the effects. R3 is presently the Lively router and R2 the standby, 토토사이트 so Allow’s increase the priority on R2 and see what happens.
R2(config)#interface ethernet0
R2(config-if)#standby 5 precedence one hundred fifty
R2#demonstrate standby
Ethernet0 – Group five
Neighborhood state is Standby, priority 150
Hellotime 4 sec, holdtime 12 sec
Upcoming hi there sent in 0.896
Virtual IP handle is 172.12.23.ten configured
Energetic router is 172.twelve.23.3, priority 100 expires in https://en.wikipedia.org/wiki/?search=먹튀검증 8.072
Standby router is area
1 point out improvements, very last point out change 00:14:24
R2 now has a greater priority, but R3 is still the active router. R2 will not get above as being the HSRP Major until eventually R3 goes down – Or maybe the preempt alternative is configured on R2.
R2(config-if)#standby five priority a hundred and fifty preempt
1d11h: %STANDBY-six-STATECHANGE: Ethernet0 Team 5 condition Standby -> Energetic
Regional state is Active, priority one hundred fifty, might preempt
Subsequent hello there despatched in 1.844
Lively router is neighborhood
Standby router is 172.twelve.23.3 expires in ten.204
Virtual mac address is 0000.0c07.ac05
two point out improvements, final point out modify 00:00:thirteen
In just a few seconds, a concept seems which the neighborhood point out has improved from standby to active. Display standby confirms that R2, the neighborhood router, has become the active router – the primary. R3 is currently the standby. Therefore if any one tells you you have to have a router down to change the Energetic router, they’re Mistaken – you only should make use of the preempt solution over the standby precedence command.
A different essential Component of HSRP configurations is recognizing the best way to change the MAC handle on the virtual router, along with interface tracking. We’ll examine Individuals attributes in the following Portion of my HSRP tutorial!
