EIGRP route summarization

Written by admin. Posted in EIGRP


By default EIGRP has auto summarization enabled. This means that it will summarize to classfull addresses at network boundaries. Leaving auto summarization enabled could cause a lot of troubles in our network. EIGRP has the ability to create summary routes at arbitrary boundaries by using manual summarization. 


Propagating EIGRP Default Route

Written by admin. Posted in EIGRP


With the use of default routes a better network performance could be achieved. For example routers at the access layer don’t need to know all routes in whole network. By using a default route you can significantly reduce the size of router’s routing table thus improving performance. There are few ways to propagate a default route into EIGRP domain, read further to see them …

This video tutorial is dedicated to basic EIGRP configuration using GNS3. also we’ll disable auto summarization, will configure a static default route and propagate it through EIGRP. (Watch the video)

Redistribution into EIGRP

When a network consist of more than one routing protocol, there could be need to advertise routes learned by one routing protocol into another and vice versa. In such a case you may want to take advantage of route redistribution feature. A simple redistribution is quite easy to do. The main configuration command is ‘redistribute’ which is used in EIGRP configuration mode.
