Enabling the EIGRP Feature

You must enable the EIGRP feature before you can configure EIGRP.
BEFORE YOU BEGIN
Ensure that you are in the correct VDC (or use the switchto vdc command).

A metric configuration (either through the default-metric configuration option or through a route
map) is required for redistribution from any other protocol, connected routes, or static routes (see
Chapter 16, "Configuring Route Policy
For graceful restart, an NSF-aware router must be up and completely converged with the network
before it can assist an NSF-capable router in a graceful restart operation.
For graceful restart, neighboring devices participating in the graceful restart must be NSF-aware or
NSF-capable.
Cisco NX-OS EIGRP is compatible with EIGRP in the Cisco IOS software.
Do not change the metric weights without a good reason. If you change the metric weights, you must
apply the change to all EIGRP routers in the same autonomous system.
Consider using stubs for larger networks.
Avoid redistribution between different EIGRP autonomous systems because the EIGRP vector
metric will not be preserved.
The no {ip | ipv6} next-hop-self command does not guarantee reachability of the next hop.
The {ip | ipv6} passive-interface eigrp command suppresses neighbors from forming.
Cisco NX-OS does not support IGRP or connecting IGRP and EIGRP clouds.
Autosummarization is not enabled by default.
Cisco NX-OS supports only IP.
