Implementing Eigrp - Cisco ASR 9000 Series Routing Configuration Manual

Implementing EIGRP

The Enhanced Interior Gateway Routing Protocol (EIGRP) is an enhanced version of IGRP developed by
Cisco. This module describes the concepts and tasks you need to implement basic EIGRP configuration
using Cisco IOS XR software. EIGRP uses distance vector routing technology, which specifies that a router
need not know all the router and link relationships for the entire network. Each router advertises destinations
with a corresponding distance and upon receiving routes, adjusts the distance and propagates the information
to neighboring routes.
For EIGRP configuration information related to the following features, see the
338 section of this module.
• Multiprotocol Label Switching (MPLS) Layer 3 Virtual Private Network (VPN)
• Site of Origin (SoO) Support

commands listed in this module, see the EIGRP Commands chapter in the Cisco ASR 9000 Series
Aggregation Services Router Routing Command Reference. To locate documentation for other commands
that might appear while executing a configuration task, search online in the Cisco IOS XR software master
command index.
