Chapter 38 Configuring IP Unicast Routing
Configuring EIGRP
To create an EIGRP routing process, you must enable EIGRP and associate networks. EIGRP sends
updates to the interfaces in the specified networks. If you do not specify an interface network, it is not
advertised in any EIGRP update.
Note If you have routers on your network that are configured for IGRP, and you want to change to EIGRP, you
must designate transition routers that have both IGRP and EIGRP configured. In these cases, perform
Steps 1 through 3 in the next section and also see the “Configuring Split Horizon” section on page 38-24.
You must use the same AS number for routes to be automatically redistributed.
Distance Internal distance: 90.
External distance: 170.
EIGRP log-neighbor changes Disabled. No adjacency changes logged.
IP authentication key-chain No authentication provided.
IP authentication mode No authentication provided.
IP bandwidth-percent 50 percent.
IP hello interval For low-speed nonbroadcast multiaccess (NBMA) networks:
60 seconds; all other networks: 5 seconds.
IP hold-time For low-speed NBMA networks: 180 seconds; all other networks:
15 seconds.
IP split-horizon Enabled.
IP summary address No summary aggregate addresses are predefined.
Metric weights tos: 0; k1 and k3: 1; k2, k4, and k5: 0
Network None specified.
NSF
1
Awareness Enabled for switches running the IP services image.
Allows Layer 3 switches to continue forwarding packets from a
neighboring NSF-capable router during hardware or software
changes.
NSF capability Disabled.
Note The Catalyst 3750 switch supports EIGRP NSF-capable
routing for IPv4.
Offset-list Disabled.
Router EIGRP Disabled.
Set metric No metric set in the route map.
Traffic-share Distributed proportionately to the ratios of the metrics.
Variance 1 (equal-cost load balancing).
1. NSF = Nonstop Forwarding
