Cisco CCNP / BCMSN Examination Tutorial: Modifying The Energetic Router In HSRP
To pass the BCMSN exam and gain your CCNP certification, you’ve obtained to find out HSRP within and out. Even though the Procedure and basic commands of HSRP are quite straightforward, there are many crucial particulars which are very easily missed but are crucial in obtaining HSRP to work how you desire it to. Let’s Consider using the precedence command accurately on equally the Test As well as in generation networks.
A vital price inside the display standby command will be the precedence. The default is one hundred, along with the router with the best precedence will be the Key HSRP router. We’ll raise the default priority on R2 and find out the final results. R3 is at present the Active router and R2 the standby, so let’s elevate the precedence on R2 and see what happens.
R2(config)#interface ethernet0
R2(config-if)#standby 5 precedence a hundred and fifty
R2#clearly show standby
Ethernet0 – Group five
Local state is Standby, priority a hundred and fifty
Hellotime four sec, holdtime 12 sec
Future hello despatched in 0.896
Virtual IP tackle is 172.12.23.ten configured
Energetic router is 172.12.23.3, precedence a hundred expires in eight.072
Standby router is regional
one state alterations, previous condition improve 00:fourteen:24
R2 now has https://www.washingtonpost.com/newssearch/?query=토토사이트 a better priority, but R3 remains to be the Energetic router. R2 will not likely get over as being the HSRP Principal until R3 goes down – Or maybe the preempt alternative is configured on R2.
R2(config-if)#standby five precedence a hundred and fifty preempt
1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Team five condition Standby -> Lively
Area point out is Active, precedence a hundred and fifty, might preempt
Up coming hello there despatched in one.844
Lively router is local
Standby router is 172.twelve.23.three expires in 10.204
Virtual mac deal with is 0000.0c07.ac05
two point out improvements, past condition transform 00:00:13
In just some seconds, a concept seems which the nearby point out has adjusted from standby to active. Show standby confirms that R2, the area router, has become the Lively router – the first. R3 has become the standby. Therefore if any individual tells you that you've to have a router all the way down to change the Lively router, they’re Mistaken – you just really need to utilize the preempt option around the standby precedence command.
