Chapter 8 Configuring EIGRP
Configuring Advanced EIGRP
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
Step 6
interface
interface-type slot/port
Example:
switch(config-router-af) interface
ethernet 1/2
switch(config-if)#
Enters interface configuration mode. Use ? to find the
supported interfaces.
Step 7
{ip | ipv6} router eigrp
instance-tag
Example:
switch(config-if)# ip router eigrp Test1
Associates this interface with the configured EIGRP
process. The instance tag can be any case-sensitive
alphanumeric string up to 20 characters.
Step 8
{ip | ipv6} authentication key-chain
eigrp
instance-tag key-chain
Example:
switch(config-if)# ip authentication
key-chain eigrp Test1 routeKeys
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.
Step 9
{ip | ipv6} authentication mode
eigrp
instance-tag
md5
Example:
switch(config-if)# ip authentication
mode eigrp Test1 md5
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.
Step 10
copy running-config startup-config
Example:
switch(config)# copy running-config
startup-config
(Optional) Saves this configuration change.
