Here's your CCNP SWITCH Training Post for Tuesday, Feb. 25!

Today's Post includes a new practice exam and a great HSRP video!

Let's get back to a daily schedule around here, shall we?  : ) 

1.   Part of the HSRP group MAC address is predetermined.  What part?

2.   Take the answer to the first question and assume HSRP group number 20.  What is that group's full MAC address?

3.   What is the minimum priority you'd have to set on an HSRP-speaking router in order to ensure it becomes the Active router?  Assume all routers have the preempt option set.

Let's check your answers right after this brief, important message!

My CCNP SWITCH Study Guide is one of the best-reviewed study guides on all of Amazon -- and it's yours in seconds for just 9.99!

Get it, then pass your CCNP SWITCH exam!   It really is that simple!

1.  Almost all of the HSRP MAC address is predetermined, actually.  HSRP's well-known MAC address is 00-00-0c-07-ac-xx, and only the "xx" at the end is unknown....

2.  ... and that "xx" is the HSRP group number IN HEX.  (Excuse the yelling.)   That would make the MAC address 00-00-0c-07-ac-14 for HSRP Group 20.

3.  With the HSRP priority 100 by default, you'd need to set the priority to 101 in order for that router to become the Active router.

Just in case you missed this video last week, I'm posting it here again.  It's much longer than the usual vids I post here, and well worth your time.

Besides, you can't beat the cost.  :)     See you Wednesday with a new practice exam, and Thursday with a new video ... right now, here's a great HSRP video to help you get a little closer to your CCNP!

Always Be Passing!
