Cisco CCNP / BCMSN Examination Tutorial: Transforming The Lively Router In HSRP
To go the BCMSN Examination and earn your CCNP certification, you’ve got to learn HSRP inside of and out. Whilst the Procedure and standard instructions of HSRP are quite easy, there are many vital specifics which might be easily ignored but are crucial in receiving HSRP to operate just how you need 먹튀검증업체 it to. Let’s Consider utilizing the precedence command properly on both the Examination and in production networks.
A crucial worth during the display standby command would be the priority. The default is 100, plus the router with the highest priority will be the Principal HSRP router. We’ll increase the default priority on R2 and find out the results. R3 is at this time the Active router and R2 the standby, so Enable’s increase the precedence on R2 and see what transpires.
R2(config)#interface ethernet0
R2(config-if)#standby five precedence 150
R2#display standby
Ethernet0 – Team five
Area point out is Standby, precedence a hundred and fifty
Hellotime 4 sec, holdtime twelve sec
Next hello sent in 0.896
Virtual IP address is 172.twelve.23.ten configured
Energetic router is 172.twelve.23.three, precedence one hundred expires in 8.072
Standby router is area
one condition improvements, previous point out change 00:14:24
R2 now has an increased priority, but R3 continues to be the Energetic router. R2 will likely not just take around because the HSRP Principal until R3 goes down – Or maybe the preempt choice is configured on R2.
R2(config-if)#standby 5 precedence 150 preempt
1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Group five condition Standby -> Active
Community state is Lively, priority one hundred fifty, may well preempt
Upcoming hello sent in 1.844
Energetic router is local
Standby router is 172.12.23.three expires in 10.204
Digital mac handle is 0000.0c07.ac05
two state adjustments, very last state improve 00:00:thirteen
In just a few seconds, a message seems that the community http://edition.cnn.com/search/?text=먹튀검증 state has transformed from standby to Energetic. Show standby confirms that R2, the area router, is currently the Energetic router – the primary. R3 is now the standby. Therefore if anyone informs you you have to have a router right down to alter the Lively router, they’re wrong – you merely need to use the preempt selection to the standby precedence command.
Another essential Section of HSRP configurations is understanding how you can alter the MAC deal with with the Digital router, in addition to interface tracking. We’ll have a look at Those people options in the following part of my HSRP tutorial!
