How does EIGRP do load balancing?

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 default variance of EIGRP?

1
EIGRP provides a mechanism to load balance over unequal cost paths throungh Variance Command. Variance is a number (1 to 128), multiplied by the local best metric then includes the routes with the lesser or equal metric. The default Variance value is 1, which means equal-cost load balancing.

What is the default hop count of EIGRP?

100
Similar to its predecessor IGRP, EIGRP has a maximum hop count of 224 and a default maximum hop count of 100. EIGRP has administrative distance of 90.

What does the default value of the EIGRP variance command of 1 mean?

What does the default value of the EIGRP variance command of 1 mean? Load balancing is disabled on this router. The router performs equal-cost load balancing. If variance is 1, it means that it support Equal cost path.

How does unequal cost load balancing in EIGRP?

configure the bandwidth of the WAN link serial 3/0 as 1000kbps between R1- R2. this make both routes unequal and we can implement and verify unequal cost load balancing….Topology:

1. Configure the topology as per the diagram.
2. Advertise the interfaces using EIGRP 100.
3. Ensure the load balancing via traceroute.

What is the advantage of unequal cost load balancing?

the capability to do unequal-cost load balancing, the capability to load-balance traffic over multiple paths that do not have the same metric to the destination. The advantage of this feature is that it offers the flexibility of load balancing, thus making more efficient use of the link.

What is the purpose of a default gateway?

The default gateway is the path used to pass information when the device doesn’t know where the destination is. More directly, a default gateway is a router that connects your host to remote network segments. It’s the exit point for all the packets in your network that have destinations outside your network.

What is equal and unequal cost load balancing?

EIGRP Equal-Cost and Unequal-Cost load balancing Routes with lowest metric get installed in the routing table by default, if two or more routes having the same metric the router will install both the routes in the routing table this is called equal cost load balancing.

What is default gateway example?

In a home or small office environment, the default gateway is a device, such as a DSL router or cable router, that connects the local network to the Internet. A device wishing to communicate with a host on the public Internet, for example, forwards the packet to the default gateway for its network segment.

How to configure unequal cost path load balancing in EIGRP?

In addition, Interior Gateway Routing Protocol (IGRP) and EIGRP also support unequal cost path load balancing. Use the variance n command in order to instruct the router to include routes with a metric of less than n times the minimum metric route for that destination. The variable n can take a value between 1 and 128.

What is the EIGRP variance command?

Introduction. EIGRP provides a mechanism to load balance over unequal cost paths throungh Variance Command. Variance is a number (1 to 128), multiplied by the local best metric then includes the routes with the lesser or equal metric. The default Variance value is 1, which means equal-cost load balancing.

What is the maximum hop count of EIGRP?

It MD5 authentication on routers running EIGRP and also has a maximum hop count close to 255. EIGRP performs load balancing over the equal-cost path and un-equal cost path. To perform the functions of EIGRP, it creates three tables which are:

What is the default cost of load balancing?

The default is 1, which means equal cost load balancing. Traffic is also distributed among the links with unequal costs, proportionately, with respect to the metric. Note: If a path is not a feasible successor, the path is not used in load balancing.
