Information About EIGRP
EIGRP combines the benefits of distance vector protocols with the features of link-state protocols.
EIGRP sends out periodic Hello messages for neighbor discovery. Once EIGRP learns a new neighbor,
it sends a one-time update of all the local EIGRP routes and route metrics. The receiving EIGRP router
calculates the route distance based on the received metrics and the locally assigned cost of the link to
that neighbor. After this initial full route table update, EIGRP sends incremental updates to only those
neighbors affected by the route change. This process speeds convergence and minimizes the bandwidth
used by EIGRP.
