Cisco CCNP / BCMSN Test Tutorial: Transforming The Lively Router In HSRP
To go the BCMSN Examination and generate your CCNP certification, you’ve got to 먹튀검증사이트 understand HSRP inside of and out. Even though the Procedure and fundamental commands https://en.search.wordpress.com/?src=organic&q=토토사이트 of HSRP are fairly straightforward, there are numerous vital particulars that happen to be simply overlooked but are crucial in obtaining HSRP to operate the way in which you desire it to. Permit’s Look into utilizing the priority command correctly on equally the Examination and in output networks.
A key benefit inside the demonstrate standby command will be the precedence. The default is one hundred, and the router with the best precedence will be the Principal HSRP router. We’ll increase the default precedence on R2 and see the results. R3 is at this time the Active router and R2 the standby, so Allow’s raise the priority on R2 and find out what happens.
R2(config)#interface ethernet0
R2(config-if)#standby 5 priority a hundred and fifty
R2#present standby
Ethernet0 – Group five
Regional condition is Standby, precedence 150
Hellotime 4 sec, holdtime 12 sec
Next hi despatched in 0.896
Virtual IP tackle is 172.twelve.23.10 configured
Energetic router is 172.12.23.three, priority a hundred expires in eight.072
Standby router is regional
1 state adjustments, last state transform 00:fourteen:24
R2 now has the next precedence, but R3 remains to be the Energetic router. R2 is not going to take above as the HSRP Main until eventually R3 goes down – Or even the preempt alternative is configured on R2.
R2(config-if)#standby 5 priority one hundred fifty preempt
1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Team five condition Standby -> Lively
Local point out is Energetic, precedence a hundred and fifty, may possibly preempt
Upcoming hi sent in 1.844
Energetic router is local
Standby router is 172.twelve.23.three expires in 10.204
Digital mac address is 0000.0c07.ac05
two state adjustments, past condition change 00:00:13
In just a couple seconds, a concept appears the regional state has transformed from standby to Energetic. Present standby confirms that R2, the area router, is currently the active router – the main. 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 Erroneous – you only really have to utilize the preempt possibility over the standby priority command.
An additional critical Component of HSRP configurations is figuring out the best way to change the MAC deal with of the virtual router, and interface tracking. We’ll examine those capabilities in the subsequent Portion of my HSRP tutorial!
