Cisco Nexus 3000 Series NX-OS Unicast Routing Configuration Guide, NX-OS Release 5.0(3)U1(1)
Chapter 4 Configuring EIGRP
Configuring Advanced EIGRP
6. (Optional) copy running-config startup-config
DETAILED STEPS
This example shows how to limit the number of redistributed routes into EIGRP:
switch# configure terminal
switch(config)# router eigrp Test1
switch(config-router)# redistribute bgp route-map FilterExternalBGP
switch(config-router)# redistribute maximum-prefix 1000 75
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 instance with the configured
instance tag.
Step 3
redistribute {bgp id | direct | eigrp id
| ospf
id | rip id | static} route-map
map-name
Example:
switch(config-router)# redistribute bgp
route-map FilterExternalBGP
Redistributes the selected protocol into EIGRP
through the configured route map.
Step 4
redistribute maximum-prefix max
[
threshold ] [warning-only | withdraw
[
num-retries timeout ]]
Example:
switch(config-router)# redistribute
maximum-prefix 1000 75 warning-only
Specifies a maximum number of prefixes that EIGRP
will distribute. The range is from 0 to 65536.
Optionally specifies the following:
• threshold—Percent of maximum prefixes that will
trigger a warning message.
• warning-only—Logs an warning message when
the maximum number of prefixes is exceeded.
• withdraw—Withdraws all redistributed routes.
Optionally tries to retrieve the redistributed
routes. The num-retries range is from 1 to 12. The
timeout is from 60 to 600 seconds. The default is
300 seconds. Use clear ip eigrp redistribution if
all routes are withdrawn.
Step 5
show running-config eigrp
Example:
switch(config-router)# show
running-config eigrp
(Optional) Displays the EIGRP configuration.
Step 6
copy running-config startup-config
Example:
switch(config-router)# copy
running-config startup-config
(Optional) Saves this configuration change.
