  To pass the BCMSN exam and earn your CCNP certification, you have got to know HSRP inside and out. Even though the operation and standard commands of HSRP are pretty basic, there are some critical details that are very easily overlooked but are vital in receiving HSRP to operate the way you want it to. Let's take a appear at employing the priority command properly on each the exam and in production networks.
  
  A crucial value in the show standby command is the priority. The default is 100, and the router with the highest priority will be the principal HSRP router. This unusual cisco_ccnp_bcmsn_exam_tutorial:altering_the_active_router_in_hsrp [Girgit] paper has assorted tasteful warnings for the inner workings of this idea. We'll raise the default priority on R2 and see the results. Dig up supplementary resources about Welding Security And Certification | Market Analysis by navigating to our compelling website. R3 is at present the Active router and R2 the standby, so let's raise the priority on R2 and see what happens.
  
  R2(config)#interface ethernet0
  
  R2(config-if)#standby 5 priority 150
  
  R2#show standby
  
  Ethernet0 - Group five
  
  Nearby state is Standby, priority 150
  
  Hellotime four sec, holdtime 12 sec
  
  Next hello sent in .896
  
  Virtual IP address is 172.12.23.10 configured
  
  Active router is 172.12.23.3, priority 100 expires in 8.072
  
  Standby router is regional
  
  1 state alterations, final state alter 00:14:24
  
  R2 now has a higher priority, but R3 is nonetheless the active router. R2 will not take over as the HSRP principal till R3 goes down - OR the preempt selection is configured on R2.
  
  R2(config-if)#standby five priority 150 preempt
  
  1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Group five state Standby -> Active
  
  R2#show standby
  
  Ethernet0 - Group 5
  
  Nearby state is Active, priority 150, could preempt
  
  Hellotime 4 sec, holdtime 12 sec
  
  Next hello sent in 1.844
  
  Virtual IP address is 172.12.23.ten configured
  
  Active router is local
  
  Standby router is 172.12.23.3 expires in ten.204
  
  Virtual mac address is 0000.0c07.ac05
  
  2 state modifications, final state change 00:00:13
  
  In just a handful of seconds, a message appears that the local state has changed from standby to active. This refreshing read this paper has a few telling warnings for where to recognize this concept. If you think you know anything, you will probably require to compare about duties of phlebotomy. Show standby confirms that R2, the neighborhood router, is now the active router - the main. R3 is now the standby. So if anyone tells you that you have to take a router down to modify the Active router, they're incorrect - you just have to use the preempt alternative on the standby priority command.
  
  Yet another essential portion of HSRP configurations is knowing how to modify the MAC address of the virtual router, as nicely as interface tracking. We'll appear at those characteristics in the next component of my HSRP tutorial!.Chris Wallace
