Cisco CCNP / BCMSN Examination Tutorial: Changing The Active Router In HSRP
To move the BCMSN Examination and make your CCNP certification, you’ve received to know HSRP within and out. Whilst the operation and basic instructions of HSRP are pretty easy, there are a few vital information that are conveniently overlooked but are critical in receiving HSRP to operate the way you'd like it to. Permit’s Consider using the priority command correctly on each the exam and in manufacturing networks.
A essential value during the display standby command is definitely the priority. The default is a hundred, along with the router with the very best priority would be the Principal HSRP router. We’ll elevate the default priority on R2 and see the outcome. R3 is currently the Lively router and R2 the standby, so Enable’s raise the precedence on R2 and find out what occurs.
R2(config-if)#standby 5 precedence one hundred fifty
Ethernet0 – Team 5
Nearby state is Standby, precedence one hundred fifty
Hellotime four sec, holdtime twelve sec
Subsequent good day sent in 0.896
Virtual IP handle is 18.104.22.168 configured
Active router is 22.214.171.124, priority a hundred expires in eight.072
Standby router is local
one state modifications, final state transform 00:14:24
R2 now has an increased precedence, but R3 remains to be the active router. R2 will 토토사이트 never choose more than because the HSRP primary until eventually R3 goes down – Or even the preempt possibility is configured on R2.
R2(config-if)#standby 5 precedence one hundred fifty preempt
1d11h: %STANDBY-six-STATECHANGE: Ethernet0 Team 5 state Standby -> Active
Neighborhood point out is Lively, precedence a hundred and fifty, may possibly preempt
Upcoming howdy sent in one.844
Lively router is neighborhood
Standby router is 172.twelve.23.three expires in 10.204
Virtual mac tackle is 0000.0c07.ac05
two state modifications, past point out modify 00:00:thirteen
In just some seconds, a information appears that the neighborhood state has modified from standby to active. Clearly show standby confirms that R2, the regional router, is currently the Lively router – the key. R3 is now the standby. So if anyone tells you you have to take a router down to change the Lively router, they’re Completely wrong – you merely really need to use the preempt option over the standby precedence command.
A different important Section of HSRP configurations is being aware of https://en.search.wordpress.com/?src=organic&q=토토사이트 how you can alter the MAC handle from the Digital router, and interface monitoring. We’ll examine People functions in the following Element of my HSRP tutorial!
