The following example shows how to redistribute BGP into EIGRP for IPv4:
switch# config t
switch(config)# router eigrp Test1
switch(config-router)# redistribute bgp 100 route-map BGPFilter
switch(config-router)# default-metric 500000 30 200 1 1500
switch(config-router)# copy running-config startup-config

Limiting the Number of Redistributed Routes

Route redistribution can add many routes to the EIGRP route table. You can configure a maximum limit
to the number of routes accepted from external protocols. EIGRP provides the following options to
configure redistributed route limits:
•
•
•
BEFORE YOU BEGIN
Ensure that you have enabled the EIGRP feature (see the
page
Ensure that you are in the correct VDC (or use the switchto vdc command).

Fixed limit—Logs a message when EIGRP reaches the configured maximum. EIGRP does not
accept any more redistributed routes. You can optionally configure a threshold percentage of the
maximum where EIGRP will log a warning when that threshold is passed.
Warning only—Logs a warning only when EIGRP reaches the maximum. EIGRP continues to
accept redistributed routes.
Withdraw—Start the timeout period when EIGRP reaches the maximum. After the timeout period,
EIGRP requests all redistributed routes if the current number of redistributed routes is less than the
maximum limit. If the current number of redistributed routes is at the maximum limit, EIGRP
withdraws all redistributed routes. You must clear this condition before EIGRP accepts more
redistributed routes.
You can optionally configure the timeout period.
