Cisco CCNP / BCMSN Test Tutorial: Shifting The Energetic Router In HSRP
To go the BCMSN Examination and make your CCNP certification, you’ve bought to find out HSRP inside of and out. Although the operation and basic commands of HSRP are quite basic, there are numerous important facts which are effortlessly missed https://en.wikipedia.org/wiki/?search=먹튀검증 but are essential in getting HSRP to operate just how you wish it to. Enable’s Look into using the precedence command effectively on both equally the Test As well as in output networks.
A vital benefit during the present standby command may be the priority. The default is a hundred, as well as router with the best priority would be the Main HSRP router. We’ll raise the default precedence on R2 and find out the outcome. R3 is now the Lively router and R2 the standby, so Permit’s elevate the priority on R2 and see what comes about.
R2(config)#interface ethernet0
R2(config-if)#standby five precedence one hundred fifty
R2#display standby
Ethernet0 – Team 5
Community condition is Standby, priority one hundred fifty
Hellotime 4 sec, holdtime twelve sec
Future hello sent in 0.896
Digital IP address is 172.12.23.ten configured
Energetic router is 172.12.23.3, priority one hundred expires in eight.072
Standby router is neighborhood
1 point out improvements, last point out adjust 00:14:24
R2 now has the next priority, but R3 remains to be the Lively router. R2 will likely not consider in excess of given that the HSRP Key until finally R3 goes down – Or perhaps the preempt possibility is configured on R2.
R2(config-if)#standby 5 precedence one hundred fifty preempt
1d11h: %STANDBY-six-STATECHANGE: Ethernet0 Group five point out Standby -> Lively
Area condition is Lively, priority a hundred and fifty, may possibly preempt
Subsequent hello despatched in one.844
Active router is community
Standby router is 172.twelve.23.3 expires in ten.204
Virtual mac tackle is 0000.0c07.ac05
two state variations, past condition adjust 00:00:thirteen
