Cisco IOS XR Routing Configuration Guide

Note This feature is supported on Cisco XR 12000 Series Routers.

EIGRP is an Interior Gateway Protocol (IGP) that supports the 6PE or 6VPE provider edge-to-customer

edge protocol by supporting the configuration of IPv6 address families in EIGRP VRF and exchanging

IPv6 routing updates in the L3VPN environment

For detailed information on configuring 6PE and 6VPE over MPLS and IP, see Cisco IOS XR

Multiprotocol Label Switching Configuration Guide.

Enabling EIGRP Routing

This task enables EIGRP routing and establishes an EIGRP routing process.

Prerequisites

Although you can configure EIGRP before you configure an IP address, no EIGRP routing occurs until

at least one IP address is configured.

SUMMARY STEPS

1. configure

2. router eigrp as-number

3. address-family {ipv4 | ipv6}

4. router-id id

5. default-metric bandwidth delay reliability loading mtu

6. distance internal-distance external-distance
