Chapter 4 Configuring EIGRP
Configuring Advanced EIGRP
This example shows how to configure MD5 message digest authentication for EIGRP over Ethernet
interface 1/2:
switch# configure terminal
switch(config)# router eigrp Test1
switch(config-router)# exit
switch(config)# interface ethernet 1/2
switch(config-if)# no switchport
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
Configuring EIGRP Stub Routing
To configure a router for EIGRP stub routing, use the following command in address-family
configuration mode:
This example shows how to configure a stub router to advertise directly connected and redistributed
routes:
switch# configure terminal
switch(config)# router eigrp Test1
switch(config-router)# address-family ipv4 unicast
switch(config-router-af)# stub direct redistributed
switch(config-router-af)# copy running-config startup-config
Use the show ip eigrp neighbor detail command to verify that a router has been configured as a stub
router. The last line of the output shows the stub status of the remote or spoke router. This example shows
the output from the show ip eigrp neighbor detail command:
Router# show ip eigrp neighbor detail
Step 10
ip 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 11
copy running-config startup-config
Example:
switch(config)# copy running-config
startup-config
(Optional) Saves this configuration change.
Command Purpose
Command Purpose
switch(config-router-af)# stub [direct |
receive-only | redistributed [direct]
leak-map map-name]
Example:
switch(config-router-af)# eigrp stub
redistributed
Configures a remote router as an EIGRP stub router.
The map name can be any case-sensitive,
alphanumeric string up to 20 characters.
