EIGRP unequal cost load balancing

EIGRP unequal cost load balancing
EIGRP unequal-cost load balancing is one of those topics that we all try to run away from. EIGRP will not perform unequal cost load balancing by default and we have to use the variance command to do so. While working through IE's vol 2 workbook, I came across a real nice lab that tested unequal cost...

EIGRP Finished….

Ok so I am satisfied with my progress so far as I have covered Switching, Frame-relay, RIPv2 and now EIGRP. I was scheduled to spend whole week on RIPv2 and EIGRP but I was able to finish them up earlier. Let's go over the notes from my EIGRP Studies. Hello Interval & Hold Time (dead interval) Routing...

Narbik’s Bootcamp – Day 2

I was not able to finish all the Frame-relay labs last night so I am already behind. I think I will dedicate my Saturday & Sunday for all the leftovers. Today we covered OSPF and EIGRP with 40% lecture and 60% hands-on labs. Narbik started off with OSPF lecture and covered every single thing about...

Narbik’s Soup-to-Nuts Workbook EIGRP Lab 6

"Lab 6 - EIGRP Stub" covers EIGRP stub routing with all the options. This was a nice lab to finish off the night with. It requires that we configure all the different options one step at a time and then answer the different questions on what we see in the routing tables. So here it is, its sunday and...

Narbik’s Soup-to-Nuts Workbook EIGRP Lab 5

"Lab 5 - EIGRP authentication and advanced configuration" requires that we configure authentication for routes and also log difference eigrp logging messages. I will refer the documentation for this. That information is pretty simple and to the point. EIGRP route authentication provides Message Digest...

Narbik’s Soup-to-Nuts Workbook EIGRP Lab 4

"Lab 4 - EIGRP Load Balancing" mostly covers the variance command. Variance command allows us to perform unequal cost load balancing if the feasibility condition is met. Only paths that are feasible can be used for load balancing and included in the routing table. The AD must be lower than the FD. Advertised...

Narbik’s Soup-to-Nuts Workbook EIGRP Lab 2

"Lab 2 - EIGRP Metric" wants us to play around with the metric values. Task 1 requires us to set up RIPv2 on R1 and advertise the directly connected networks. Piece of cake! Task 2 moves on to R2 which will be the redistribution point in our network. We configure couple of networks in RIPv2 and a couple...

Narbik’s Soup-to-Nuts Workbook EIGRP Lab 1

"Lab 1 - Configuring EIGRP and adjusting timers" - Task 1 requires that I configure EIGRP on four routers and advertise their directly connected networks. I am actually liking this format where you configure the basic routing protocol over and over again until you are really good with it.   Command Purpose Step 1  Router(config)# router...
