Chapter 8 Configuring EIGRP
Configuring Advanced EIGRP
Ensure that you are in the correct VDC (or use the switchto vdc command).
SUMMARY STEPS
1. config t
2. router eigrp instance-tag
3. address-family {ipv4 | ipv6} unicast
4. authentication key-chain key-chain
5. authentication mode md5
6. interface interface-type slot/port
7. {ip | ipv6} router eigrp instance-tag
8. {ip | ipv6} authentication key-chain eigrp instance-tag key-chain
9. {ip | ipv6} authentication mode eigrp instance-tag md5
10. copy running-config startup-config
DETAILED STEPS
Command Purpose
Step 1
config t
Example:
switch# config t
switch(config)#
Enters configuration mode.
Step 2
router eigrp instance-tag
Example:
switch(config)# router eigrp Test1
switch(config-router)#
Creates a new EIGRP process with the configured
instance tag. The instance tag can be any case-sensitive
alphanumeric string up to 20 characters.
If you configure an instance-tag that does not qualify
as an AS number, you must use the
autonomous-system command to configure the AS
number explicitly or this EIGRP instance will remain
in the shutdown state.
Step 3
address-family {ipv4 | ipv6} unicast
Example:
switch(config-router)# address-family
ipv4 unicast
switch(config-router-af)#
Enters the address-family configuration mode. This
command is optional for IPv4.
Step 4
authentication key-chain key-chain
Example:
switch(config-router-af)# authentication
key-chain routeKeys
Associates a key chain with this EIGRP process for
this VRF. The key chain can be any case-sensitive
alphanumeric string up to 20 characters.
Step 5
authentication mode md5
Example:
switch(config-router-af)# authentication
mode md5
Configures MD5 message digest authentication mode
for this VRF.
