OSPF Load Balancing and Tweaking

Learn how to change the reference bandwidth, the costs on ports as well as the maximum allowed equal cost paths that may be used in OSPF.

Very cool, thanks! I love how you explain some things and then pause with a question to make us really incorporate what we just learned.

[@McGavel1]

Amazing stuff man! Thanks again! Edit: I especially love the points you made about what happens if you shutdown subinterfaces only on one side of a link.

God Keith how I wish I could matrix style upload your networking knowledge into my brain.

Hmmm I think I am getting better and better everyday with ospf. Thank you keith.

[@scottspa74]

Great, great video. Interesting config to illustrate the principle.

[@KeithBarker]

Thank you Scott Sparling!

Hi Keith, I think is the other way around here 5:44 for the calculation of cost. Great video!

[@Shrrik]

Very good video, clear on the ospf load balance concept!

[@shaikarshad9670]

Thanks this was a very good video, clear on the ospf

Hi Matt- I used GNS3 for this demo. CBT Nuggets as a complete GNS3 series if you are interested in learning more about GNS3. I also have some free videos here on KZbin about GNS3 as well. Thanks for the question, Keith

[@GoodGameOKC1]

Beautiful!! Thanks a million for the video Keith really cleared up some doubts I had.

[@paules0099]

As per usual, great learning tips from you, Keith! Quick question, say you have to load balance between serial and fastethernet. How much cost manipulation is needed to make that happen? Is there a math formula to figure this out or should I just continue inputting numbers to get the balance that is needed. Thanks!

Wonderful tweak!

Thanks, Keith.

Hey Keith, I was working on a similar setup. In my case I had a router 0 connected to router 1. In my tests, when I traceroute from router 1 it looks like it load balances, however when I traceroute from router 0, it only takes one path. Have you seen this before?

[@rahmananam1]

Love it. Thanks

The video is smudgy, is this only for me?

Keith i know it's been almost 7 years already, but could you make a video explaining the 3 types of NAT please? My final exam of Telematic Networks is the next week and im kind of struggling while i try to learn about NAT, i already saw your video of PAT NAT but i think i ended up more confused X_X

[@alexcalderaro162]

is there a command that would show all the routes after you changed that 2 first to 5?

[@KeithBarker]

Hi Keith, would R2 stop advertising the 20.0.0.0 network after the default ospf 30min update refresh time? Thanks for your efforts
