Chapter 39 Configuring IP Unicast Routing
IP EIGRP provides increased network width. With RIP, the largest possible width of your network is
15 hops. Because the EIGRP metric is large enough to support thousands of hops, the only barrier to
network expansion is the transport-layer hop counter. EIGRP increments the transport control field only
when an IP packet has traversed 15 routers and the next hop to the destination was learned through
EIGRP. When a RIP route is used as the next hop to the destination, the transport control field increments
as usual.
EIGRP offers these features:
Fast convergence.
•
Incremental updates when the state of a destination changes rather than sending the entire contents
•
of the routing table, minimizing the bandwidth required for EIGRP packets.
Less CPU usage because full update packets need not be processed each time they are received.
•
Protocol-independent neighbor discovery mechanism to learn about neighboring routers.
•
Variable-length subnet masks (VLSMs).
•
Arbitrary route summarization.
•
Scalable for large networks.
