Result Simulation

Pre-requisite: EIGRP Configuration, EIGRP Implementation in Cisco.

With respect to EIGRP or any Interior Gateway Protocol (IGP), route summarization is a significant tool to create a boundary for query propagation and is needed to create a single route entry with a prefix & prefix length larger than one or smaller component routes.

Route summarization reduces the amount of routing information that routers must exchange, process, and maintain, which ultimately allows for faster topology convergence and less CPU utilization of the router within the network. Summarization also restricts the size of an area that is affected by network changes By hiding the changes in the individual networks behind a single advertised summary route that encompasses all the component routes.

EIGRP supports 2 types of route summarization :

1. Automatic summarization
2. Manual summarization
