Does EIGRP load balance by default?

Does EIGRP load balance by default?

EIGRP load balancing By default, EIGRP supports equal-cost load balancing over four links. Equal-cost means that multiple routes must have the same metric to reach the destination, so that router can choose to load balance across equal cost links.

How does EIGRP do load balancing?

Configure Load Balancing on Cisco EIGRP using Unequal Routes

1. Examine the current best route to the destination. On the originating router, use command show ip route [destination IP] to show the best route to reach the destination IP.
2. Identify EIGRP Feasible Successor (FS) routes.
3. Configure the variance value.

What is the protocol that supports the unequal cost load balancing and how does it happened?

EIGRP supports equal cost load balancing and is also the only routing protocol to support unequal cost load balancing. Unequal cost load balancing is when a router distributes traffic over network interfaces, even those that are different distances from the destination address.

Does EIGRP support unequal load balancing?

EIGRP Load Balancing. Every routing protocol supports equal cost path load balancing. In addition, Interior Gateway Routing Protocol (IGRP) and EIGRP also support unequal cost path load balancing. The default is 1, which means equal cost load balancing.

How to do unequal-cost load balancing in EIGRP?

To accomplish unequal-cost load balancing, the variance command is used. The command takes one parameter, the multiplier, which tells the router to load balance across each link with the metric for the destination less than the feasible distance multiplied by the multiplier value. The multiplier value, by default, is 1. The maximum value is 128.

What are the advantages and disadvantages of EIGRP?

One of the advantages of EIGRP is that, unlike OSPF and many other routing protocols, EIGRP also supports unequal-cost load balancing. You can set up your router to load balance over links with different metric to reach the destination. To accomplish unequal-cost load balancing, the variance command is used.

How does the variance command work in EIGRP?

To accomplish unequal-cost load balancing, the variance command is used. The command takes one parameter, the multiplier, which tells the router to load balance across each link with the metric for the destination less than the feasible distance multiplied by the multiplier value.

How can I force EIGRP on my router?

By using the same preshared key (PSK) on all routers you can force EIGRP to authenticate each EIGRP message. That way you can ensure that your router accepts routing updates only from the trusted sources.
