Chapter 8 Configuring EIGRP
Configuring Basic EIGRP
EIGRP must be able to obtain a router ID (for example, a configured loopback address) or you must
configure the router ID option.
If you configure an instance tag that does not qualify as an AS number, you must configure the AS
number explicitly or this EIGRP instance will remain in the shutdown state.
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. autonomous-system as-number
4. interface interface-type slot/port
5. {ip | ipv6} router eigrp instance-tag
6. show {ip | ipv6} eigrp interfaces
7. 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
autonomous-system as-number
Example:
switch(config-router)# autonomous-system
33
(Optional) Configures a unique AS number for this
EIGRP instance. The range is from 1 to 65535.
Step 4
log-adjacency-changes
Example:
switch(config-router)#
log-adjacency-changes
(Optional). Generates a system message whenever an
adjacency changes state. This command is enabled by
default.
Step 5
log-neighbor-warnings [ seconds]
Example:
switch(config-router)#
log-neighbor-warnings
(Optional) Generates a system message whenever a
neighbor warning occurs. You can configure the time
between warning messages, from 1 to 65535, in
seconds. The default is 10 seconds. This command is
enabled by default.
