EIGRP – Best Path Selection

Tuesday, March 27th, 2012

By default EIGRP uses bandwidth and delay of the line to determine the best path to a remote network. However, if desired, EIGRP can use a composite of four metrics: bandwidth, delay, reliability, and load. Maximum transmission unit (MTU) is not used in EIGRP calculations but is a required parameter in some EIGRP-related commands. Also, by default, EIGRP will provide equal-cost load balancing across up to four links. You can disable load balancing by setting the ‘maximum-paths’ to ’1′. In this lab I use four Cisco 3725 routers [IOS 12.4(15)T10] to demonstrate EIGRP path selection behavior on Cisco routers. (more…)

Creating a LAG between an ESXi vSwitch and a Physical Switch

Sunday, October 30th, 2011

In this lab I am going to create a LAG (Link Aggregation Group) between an ESXi vSwitch and a physical switch. You can use Cisco, Force10 Dell, Juniper, or any other manufacturer for the physical switch. Depending on the switch you use, the commands may vary on the physical switch for creating a LAG (referred to as port-channel by Force10 Dell and etherchannel by Cisco). I will not get into details of creating a LAG; please reference my earlier posts Creating a Link Aggregation Group (LAG) in FTOS and Setting up Cisco EtherChannels – Static, PAgP, and LACP for this information.

Load Balancing with EIGRP

Wednesday, September 14th, 2011

RIP, RIPv2, IGRP, EIGRP and OSPF are all routing protocols that support equal cost load balancing but IGRP and EIGRP can also support unequal cost load balancing. However, unlike IGRP, EIGRP supports VLSM (Variable Length Subnet Masking). Below I use a Cisco 3560G router [IOS Version 12.2(40)SE] to show how you can have EIRGP load-balance across up to 32 links (equal or unequal). By default, EIGRP will provide equal-cost load balancing across up to 4 links. You can disable load balancing by setting the ‘maximum-paths’ to ’1′. (more…)
