Use the
no
forms of these commands to disable the feature or return the setting to the default value.
Configuring EIGRP Route Authentication
EIGRP route authentication provides MD5 authentication of routing updates from the EIGRP routing
protocol to prevent the introduction of unauthorized or false routing messages from unapproved sources.
Beginning in privileged EXEC mode, follow these steps to enable authentication:
Step 10
show ip eigrp interface
Display which interfaces EIGRP is active on and
information about EIGRP relating to those interfaces.
Step 11
copy running-config startup-config
(Optional) Save your entries in the configuration file.

Step 6
exit
Return to global configuration mode.
Step 7
key chain
name-of-chain
