Cisco CCNP / BCMSN Exam Tutorial: Changing The Active Router In HSRP
To pass the BCMSN Test and generate your CCNP certification, you’ve acquired to be aware of HSRP inside and out. Even though the Procedure and primary commands of HSRP are pretty very simple, there are some critical details that are simply disregarded but are crucial in having HSRP to work the way you need it to. Let’s Check out utilizing the priority command appropriately on both of those the exam and in generation networks.
A critical value in the clearly show standby command is definitely the precedence. The default is 100, plus the router with the very best priority would be the Major HSRP router. We’ll increase the default priority on R2 and find out the effects. R3 is presently the Energetic router and R2 the standby, so Allow’s raise the precedence on R2 and see what comes about.
R2(config)#interface ethernet0
R2(config-if)#standby 5 priority 150
R2#display standby
Ethernet0 – Team five

R2 now has a greater precedence, but R3 continues to be the Lively router. R2 won't get around because the HSRP Major until finally R3 goes down – Or perhaps the preempt choice is configured on R2.

In only a few seconds, a concept seems the area state has changed from standby to active. Display standby confirms that R2, the regional router, is now the active router – the first. R3 has become the standby. Therefore if any one tells you that you've got to take a router all the way down to alter the Lively router, they’re Completely wrong – you only have to use the preempt choice on the standby precedence command.
An additional crucial A part of HSRP configurations is realizing the way to change the MAC deal with with the Digital router, in addition to interface monitoring. We’ll have a look at Individuals characteristics in the subsequent Section of my HSRP tutorial!
