DETAILED STEPS
Command Purpose
Step 1
configure terminal
Example:
switch# configure terminal
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
bfd
Example:
switch(config-router-neighbor)# bfd
(Optional) Enables BFD for all EIGRP interfaces.
Step 4
interface int-if
Example:
switch(config-router-neighbor)#
interface ethernet 2/1
switch(config-if)#
Enters interface configuration mode. Use the ?
keyword to display the supported interfaces.
Step 5
ip eigrp instance-tag bfd
Example:
switch(config-if)# ip eigrp Test1 bfd
(Optional) Enables or disables BFD on an EIGRP
interface. The instance tag can be any case-sensitive,
alphanumeric string up to 20 characters.
The default is disabled.
Step 6
show ip eigrp [vrf vrf-name] [interfaces
if]
Example:
switch(config-if)# show ip eigrp
(Optional) Displays information about EIGRP. The
vrf-name can be any case-sensitive, alphanumeric
string up to 32 characters.
Step 7
copy running-config startup-config
Example:
switch(config-if)# copy running-config
startup-config
(Optional) Saves this configuration change.
