Cisco IOS XR Routing Configuration Guide
default route learned from the neighbors is displaced by the summary default route or the summary route 
is the only default route present, all traffic destined for the default route does not leave the router; 
instead, this traffic is sent to the null 0 interface, where it is dropped. 
The recommended way to send only the default route from a given interface is to use a route-policy 
command. 
SUMMARY STEPS
1. configure
2. router eigrp as-number
3. address-family {ipv4 | ipv6} 
4. route-policy name out
5. interface type instance
6. summary-address ip-address {/length | mask} [admin-distance]
7. end

DETAILED STEPS
Command or Action Purpose
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters global configuration mode.
Step 2
router eigrp 
as-number
Example:
RP/0/RP0/CPU0:router(config)# router eigrp 100
Configures an EIGRP routing process.
Step 3
address-family {ipv4 | ipv6} 
Example:
RP/0/RP0/CPU0:router(config-eigrp)# 
address-family ipv4
Enters an address family configuration mode.
Step 4
route-policy 
name
 out
Example:
RP/0/RP0/CPU0:router(config-eigrp-af)# 
route-policy FILTER_DEFAULT out
Applies a routing policy to updates advertised to or received 
from an EIGRP neighbor.
Step 5
interface 
type
instance
Example:
RP/0/RP0/CPU0:router(config-eigrp-af)# 
interface pos 0/1/0/0 
Defines the interfaces on which the EIGRP routing protocol 
runs.
