Cisco CCNP / BCMSN Examination Tutorial: Transforming The Lively Router In HSRP
To go the BCMSN exam and generate your CCNP certification, you’ve obtained to be aware of HSRP inside and out. Even though the Procedure and primary instructions of HSRP are really straightforward, there are numerous critical specifics which can be very easily overlooked but are important in finding HSRP to operate the way in which you want it to. Allow’s take a look at utilizing the priority command appropriately on the two the exam and in creation networks.
A key worth during the exhibit standby command could be the precedence. https://www.washingtonpost.com/newssearch/?query=토토사이트 The default is 100, plus the router with the highest priority would be the Most important HSRP router. We’ll elevate the default precedence on R2 and find out the final results. R3 is at present the Active router and R2 the standby, so Permit’s elevate the priority on R2 and see what comes about.
R2(config-if)#standby five priority 150
Ethernet0 – Group five
Nearby state is Standby, precedence a hundred 안전공원 and fifty
Hellotime 4 sec, holdtime 12 sec
Up coming hello there despatched in 0.896
Digital IP tackle is 172.twelve.23.10 configured
Energetic router is 172.12.23.three, priority one hundred expires in 8.072
Standby router is area
one point out changes, final condition modify 00:14:24
R2 now has a better priority, but R3 remains to be the Energetic router. R2 won't take over given that the HSRP primary right until R3 goes down – OR the preempt selection is configured on R2.
R2(config-if)#standby 5 priority 150 preempt
1d11h: %STANDBY-six-STATECHANGE: Ethernet0 Team 5 point out Standby -> Lively
Regional condition is Lively, precedence a hundred and fifty, might preempt
Subsequent good day sent in 1.844
Active router is nearby
Standby router is 172.twelve.23.3 expires in ten.204
Virtual mac address is 0000.0c07.ac05
2 state improvements, previous point out change 00:00:thirteen
In just a few seconds, a information appears the regional state has transformed from standby to active. Demonstrate standby confirms that R2, the community router, is currently the Lively router – the principal. R3 has become the standby. Therefore if anyone informs you that you have to have a router all the way down to alter the Lively router, they’re Mistaken – you just must utilize the preempt selection around the standby precedence command.
Another important Component of HSRP configurations is realizing ways to alter the MAC handle of the Digital router, along with interface tracking. We’ll have a look at those capabilities in the next Section of my HSRP tutorial!
