To pass the BCMSN exam and win your CCNP, you must know HSRP all around! Some portion of that is knowing how the Macintosh address of the virtual switch is determined, and another part is knowing how to change this address. We'll take a gander at the two components in this instructional exercise.
We have two switches on a portion running HSRP, so first we have to discover what the Macintosh address of the HSRP virtual switch is. The show summon for HSRP is indicate standby, and it's the primary order you should run while designing and investigating HSRP. We should run it on the two switches and look at comes about.

R3 is in the Dynamic state, while R2 is in Standby. The hosts are utilizing the 172.12.123.10 address as their portal, yet R3 is really taking care of the workload. R2 will assume control if R3 winds up plainly inaccessible.
An IP deliver was statically allocated to the virtual switch, yet not a Macintosh address. In any case, there is a Macintosh address under the show standby yield on R3, the dynamic switch. How did the HSRP procedure touch base at a Macintosh of 00-00-0c-07-air conditioning 05?
All things considered, the greater part of the work is as of now done before the design is even started. The Macintosh address 00-00-0c-07-air conditioning xx is held for HSRP, and xx is the gathering number in hexadecimal. That is a decent aptitude to have for the exam, so ensure you're OK with hex transformations. The gathering number is 5, which is communicated as 05 with a worthless hex character. On the off chance that the gathering number had been 17, we'd see 11 toward the finish of the Macintosh address – one unit of 16, one unit of 1.
On uncommon events, you may need to change the Macintosh deliver appointed to the virtual switch. This is finished with the standby Macintosh address order. Simply ensure you're not copying a Macintosh address that is now on your system!

The Macintosh address will take a couple of moments to change, and the HSRP switches will go into Learn state for that day and age.
A certifiable HSRP investigating note: On the off chance that you see steady state changes with your HSRP design, do what you ought to dependably do while investigating – check the physical layer first. Good luck on your BCMSN exam!
