Phuc… I am unsure too. In my studies the mac for GLBP was 0007.b400.0A01 (that being the last two 01 are the router ID). The more confusing part well… is I think 000A is the group number. A= 9 (I choose group 9 at the time). 4 digits for the router group and 2 for the router ID.

I have a questions:
In the lecture, “The virtual MAC address in GLBP is 0007.b400.xxyy where xx is the GLBP group number and yy is the different number of each gateway (01, 02, 03…)… GLBP supports up to 1024 virtual routers (GLBP groups) per physical interface of a router.”

But xx is 8 bit length string, so i think GLBP supports only 256 virtual groups only, not 1024 groups. Is it right? If anyone know, pls let me know. Thank you.

@Vivek…this is just the basic…

(config-if)#glbp 1 ip 192.168.1.7
###the 1 in the command is the Group #. The ip address is the virtual gateway###

(config-if)#glbp 1 priority 110
###priority is default at 100 but you can configure it to be a higher or lower number###

There are other commands for authentication, preemption, weighting and tracking…

If there is anything i ever looked for soooooooooooooo much in life, it was what to do for our default gateway since we have four links to the internet but when i landed on this, i got a salary increment because all my predecessors had failed to do this they could be flipping DHCP settings to accommodate the available links!!!!!!!!!!!!!! am a pro now. thumbs up to 9tut….

really really good explanation…..you deserved to write a mini-book of these tutorials you write…as it is made so simple to understand. To al ccna students, if you want to pass your CCNA, learn proper CCNA concepts and you’ll be able to work any questions…..learn concept is the best way, even for interviews it will be useful to you, as once you remember it, get the logic, it will stay forever.

Excellent, very precise with no extra unnecessary information, just what one would need to understand the concept how GLBP works, hours earlier I was CLUELESS as to how this protocol works, heck I had even forgotten what the acronyms stands for, but with this summary I was able to refresh my mind and now I posses a solid concept, that I will use when answering the questions once I take the ICDN – 200 120, Now moving on to the commands…

Thanks You 9Tut.
