Did you write anything about variance & load-balancing in EIGRP?

22

Hi Brutus,

Sure did:

Hope that helps!

Nice!

Rene, you rock man, I really enjoyed the video, because I got lot of confusing in understanding AD & FD , SUCCESSOR & FEASIBLE SUCCESSOR. but you made I easy for me.
thanks bro. keep going

25

Im lost of words. Be blessed!!!

26

Excellent explanation.

Dear Rene

I am really thankful to you.

You give explaination in such a easy manner that I dont have to again read that topic.

Would like to know that do u publish the book for CCNA, CCNP Routing & Switching,CCIE R&S

Dear Pankaj,

Glad to hear you like it. I do have a few booksā€¦one for CCNA R&S and I have a book for CCNP ROUTE, SWITCH and TSHOOT. You can find them on my other website:

Hi Rene,

This is the first time, Iā€™m reading about EIGRP routing protocol and i 've understood the most. Tough bit not clear on why Clubs choose Advertise distance as 25 and Diamond as 19 instead of others distances. Your explanation is simple and awesome:). Iā€™m planning to extend my trail period.

Thanks,
Maruti.

Hi Maruti,

Thank you, good to hear you liked it. The distance of 19 is calculated as following:

- Router Spade advertises a distance of 5 to router Hearts.
- Router Hearts advertises a distance of 5+4 = 9 to router Clubs.
- Router Clubs advertises a distance of 5+4+3 = 12 to router Diamond.
- Router Diamond advertises a distance of 5+4+3+7 = 19 to router Hearts.

This is an example of how this route ā€œloopsā€ back to router Hearts. Keep in mind that EIGRP is a distance vector routing protocol, it doesnā€™t have a clue what the topology looks likeā€¦the only thing it knows is that it receives information about routes on a certain interface with a certain distance.

Great work. That makes clear that things are only difficult when u dont know them. And u seem to master it all. I am delighted.

Excellent explanation. Thanks for all the effort that you have put into this site.

33

Thanks Paul!

34

Great example!! Had to train my mind that Routers dont know topology, but I do looking at map!Finally got it!

35

Very clear and Excellent explanation! You are awesome.

36

Rene,

Thanks for the great article, I am learning a lot from your website.

You are welcome Chris, good to hear you like it!

Hi Rene,

Where can I find the video that explains why we use that specific Feasible Successor rule to prevent loops?

Thanks
Rob

Hi Rob,

Do you mean the example with this picture?

I didnā€™t record a video (yet) for that part but if you are interested, I can create one.
