  To pass the BCMSN exam and earn your CCNP certification, you've got to know HSRP inside and out. Whilst the operation and fundamental commands of HSRP are pretty simple, there are some critical particulars that are effortlessly overlooked but are essential in getting HSRP to perform the way you want it to. Here includes more concerning how to flirt with this idea. Let's take a appear at making use of the priority command correctly 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 main HSRP router. We'll raise the default priority on R2 and see the final results. Dig up further on an affiliated article directory by clicking find out more. R3 is presently 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 five priority 150
  
  R2#show standby
  
  Ethernet0 - Group 5
  
  Local state is Standby, priority 150
  
  Hellotime 4 sec, holdtime 12 sec
  
  Next hello sent in .896
  
  Virtual IP address is 172.12.23.ten configured
  
  Active router is 172.12.23.three, priority one hundred expires in eight.072
  
  Standby router is neighborhood
  
  1 state adjustments, final state change 00:14:24
  
  R2 now has a greater priority, but R3 is still the active router. R2 will not take more than as the HSRP primary till R3 goes down - OR the preempt choice is configured on R2.
  
  R2(config-if)#standby five priority 150 preempt
  
  1d11h: %STANDBY-six-STATECHANGE: Ethernet0 Group five state Standby -> Active
  
  R2#show standby
  
  Ethernet0 - Group five
  
  Neighborhood state is Active, priority 150, might preempt
  
  Hellotime 4 sec, holdtime 12 sec
  
  Subsequent hello sent in 1.844
  
  Virtual IP address is 172.12.23.10 configured
  
  Active router is regional
  
  Standby router is 172.12.23.3 expires in ten.204
  
  Virtual mac address is 0000.0c07.ac05
  
  two state modifications, last state modify 00:00:13
  
  In just a couple of seconds, a message seems that the regional state has changed from standby to active. Show standby confirms that R2, the nearby router, is now the active router - the main. R3 is now the standby. Identify supplementary resources on the affiliated wiki - Click this link: tumbshots. So if anyone tells you that you have to take a router down to modify the Active router, they are incorrect - you just have to use the preempt choice on the standby priority command.
  
  An additional crucial element of HSRP configurations is understanding how to change the MAC address of the virtual router, as effectively as interface tracking. We'll look at these attributes in the subsequent element of my HSRP tutorial!.Chris Wallace
