Cisco CCNP / BCMSN Test Tutorial: Modifying The Energetic Router In http://www.bbc.co.uk/search?q=토토사이트 HSRP
To move the BCMSN Test and receive your CCNP certification, you’ve got to know HSRP inside of and out. Though the Procedure and simple instructions of HSRP are pretty easy, usually there are some vital specifics which might be easily ignored but are crucial in having HSRP to work the way in which you need it to. Let’s Check out utilizing the precedence command the right way on each the Examination and in generation networks.
A essential benefit within the present standby command will be the priority. The default is a hundred, plus the router with the very best precedence would be the Most important HSRP router. We’ll elevate the default priority on R2 and see the effects. R3 is currently the Energetic router and R2 the standby, so Permit’s raise the priority on R2 and see what occurs.
R2(config)#interface ethernet0
R2(config-if)#standby 5 priority one hundred fifty
R2#clearly show standby
Ethernet0 – Group 5
Area condition is Standby, precedence one hundred fifty
Hellotime 4 sec, holdtime twelve sec
Next hello there despatched in 0.896
Virtual IP handle is 172.12.23.ten configured
Energetic router is 172.12.23.3, precedence 100 expires in eight.072
Standby router is neighborhood
one point out alterations, past state modify 00:14:24
R2 now has a better precedence, but R3 is still the Lively router. R2 won't just take in excess of since the HSRP Main until R3 goes down – Or even the preempt alternative is configured on R2.
R2(config-if)#standby five priority 150 preempt
1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Group five condition Standby -> Lively
Area point out is Lively, precedence 150, may perhaps preempt
Upcoming howdy sent in 1.844
Lively router is neighborhood
Standby router is 172.twelve.23.3 expires in ten.204
Digital mac handle is 0000.0c07.ac05
two point out variations, last point out alter 00:00:13

So if anybody informs you that you have to take a router down to change the Active router, they’re Improper – you simply really need to use the preempt alternative to the standby precedence command.
A different crucial Element of HSRP configurations is figuring out the best way to alter the MAC deal with on the Digital router, together with interface tracking. We’ll evaluate Individuals options in the following part of my HSRP tutorial!
