Cisco Nexus 3548 Switch NX-OS Unicast Routing Command Reference

Chapter Unicast Routing Commands
ip next-hop-self eigrp
ip next-hop-self eigrp
To instruct the Enhanced Interior Gateway Routing Protocol (EIGRP) process to use the local IP address
as the next-hop address when advertising these routes, use the ip next-hop-self eigrp command. To use
the received next-hop value, use the no form of this command.
ip next-hop-self eigrp instance-tag
no ip next-hop-self eigrp instance-tag
Syntax Description
Command Default EIGRP always sets the IP next-hop value to be itself.
Command Modes Interface configuration mode
Command History
Usage Guidelines EIGRP, by default, sets the IP next-hop value to be itself for routes that it is advertising, even when
advertising those routes on the same interface from which the router learned them. To change this
default, you must use the no ip next-hop-self eigrp command to instruct EIGRP to use the received
next-hop value when advertising these routes.
This command requires the LAN Enterprise Services license.
Examples This example shows how to change the default IP next-hop value and instruct EIGRP to use the received
next-hop value:
switch# configure terminal
switch(config)# router eigrp 209
switch(config-router)# interface ethernet 2/1
switch(config-if)# no switchport
switch(config-if)# no ip next-hop-self eigrp 209
switch(config-if)#
Related Commands
instance-tag Name of the EIGRP instance. The instance-tag can be any
case-sensitive, alphanumeric string up to 20 characters.
Release Modification
5.0(3)A1(1) This command was introduced.
Command Description
copy running-config
startup-config
Saves the configuration changes to the startup configuration file.
show ip eigrp Displays EIGRP information.
