Command
Step 6
interface interface-type slot/port
Example:
switch(config-router-af) interface
ethernet 1/2
switch(config-if)#
Step 7
{ip | ipv6} router eigrp instance-tag
Example:
switch(config-if)# ip router eigrp Test1
Step 8
{ip | ipv6} authentication key-chain
eigrp instance-tag key-chain
Example:
switch(config-if)# ip authentication
key-chain eigrp Test1 routeKeys
Step 9
{ip | ipv6} authentication mode eigrp
instance-tag md5
Example:
switch(config-if)# ip authentication
mode eigrp Test1 md5
Step 10
copy running-config startup-config
Example:
switch(config)# copy running-config
startup-config
The following example shows how to configure MD5 message digest authentication for EIGRP over
Ethernet interface 1/2:
switch# config t
switch(config)# router eigrp Test1
switch(config-router)# exit
switch(config)# interface ethernet 1/2
switch(config-if)# ip router eigrp Test1
switch(config-if)# ip authentication key-chain eigrp Test1 routeKeys
switch(config-if)# ip authentication mode eigrp Test1 md5
switch(config-if)# copy running-config startup-config

Purpose
Enters interface configuration mode. Use ? to find the
supported interfaces.
Associates this interface with the configured EIGRP
process. The instance tag can be any case-sensitive
alphanumeric string up to 20 characters.
Associates a key chain with this EIGRP process for
this interface. This configuration overrides the
authentication configuration set in the router VRF
mode.
The instance tag can be any case-sensitive
alphanumeric string up to 20 characters.
Configures the MD5 message digest authentication
mode for this interface. This configuration overrides
the authentication configuration set in the router VRF
mode.
The instance tag can be any case-sensitive
alphanumeric string up to 20 characters.
(Optional) Saves this configuration change.
