Cisco CCNP / BCMSN Test Tutorial: Switching The Energetic Router In HSRP
To pass the BCMSN Test and get paid your CCNP certification, you’ve acquired to find out HSRP inside http://www.bbc.co.uk/search?q=토토사이트 and out. Even though the operation and simple instructions of HSRP are really easy, there are numerous important aspects that are simply missed but are vital in getting HSRP to work the way you need it to. Allow’s Look into using the priority command appropriately on each the Test As well as in output networks.
A key worth from the demonstrate standby command is the priority. The default is 100, along with the router with the highest priority will be the Principal HSRP router. We’ll raise the default precedence on R2 and find out the effects. R3 is at present the Energetic router and R2 the standby, so Allow’s increase the precedence on R2 and find out what occurs.
R2(config)#interface ethernet0
R2(config-if)#standby 5 precedence one hundred fifty
R2#show standby
Ethernet0 – Group 5
Local point out is Standby, priority a hundred and fifty
Hellotime 4 sec, holdtime 12 sec
Up coming howdy sent in 0.896
Digital IP deal with is 172.twelve.23.10 configured
Active router is 172.12.23.three, precedence one hundred expires in eight.072
Standby router is regional
1 state improvements, previous condition change 00:14:24
R2 now has the next precedence, but R3 is still the Lively router. R2 will not choose in excess of given that the HSRP Major right until R3 goes down – Or maybe the preempt option is configured on R2.
R2(config-if)#standby 5 priority one hundred fifty preempt
1d11h: %STANDBY-6-STATECHANGE: 토토사이트 Ethernet0 Team 5 point out Standby -> Active
Regional state is Energetic, precedence a hundred and fifty, might preempt
Upcoming hello there sent in 1.844
Lively router is nearby
Standby router is 172.twelve.23.three expires in ten.204
Digital mac deal with is 0000.0c07.ac05
2 state improvements, past state transform 00:00:thirteen
In just some seconds, a message appears the regional state has altered from standby to active. Clearly show standby confirms that R2, the community router, has become the Energetic router – the first. R3 is now the standby. Therefore if any one tells you that you've got to have a router right down to change the Lively router, they’re wrong – you only really need to utilize the preempt solution around the standby priority command.
A further essential Section of HSRP configurations is being aware of how to alter the MAC tackle with the virtual router, in addition to interface tracking. We’ll check out All those attributes in the next Element of my HSRP tutorial!
