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.
Nonstop Forwarding Awareness
The EIGRP NSF Awareness feature is supported for IPv4 in the IP services image. When the neighboring router is
NSF-capable, the Layer 3 switch continues to forward packets from the neighboring router during the interval between
the primary Route Processor (RP) in a router failing and the backup RP taking over, or while the primary RP is manually
reloaded for a nondisruptive software upgrade.
This feature cannot be disabled. For more information on this feature, see the “Configuring Nonstop Forwarding” chapter
in the High Availability Configuration Guide, Cisco IOS Release 15S.
Configuring Basic EIGRP Parameters
In this procedure, configuring the routing process is required; other steps are optional.
