Symptoms of a Poorly Scaled Eigrp Network

Poorly scaled EIGRP networks can result in the following:

• Network congestion

— Routing information being lost

— Flapping routes

— Retransmission

• Router memory running low

• Router CPU overutilized

• Unreliable circuit or unidirectional link

Some of these symptoms are caused by other factors, such as poor design, with resources overwhelmed by the tasks assigned. Often many of these symptoms will be characterized by a route being flagged as SIA, as the router waits for a reply from a neighbor across a network that cannot handle the demands made upon it.

Careful design and placement of network devices can remedy many of the problems seen in a network.
