Monitoring and Maintaining EIGRP

To delete neighbors from the neighbor table, use the following command:
Command
Switch# clear ip eigrp neighbors [ip-address |
interface]
To display various routing statistics, use the following commands:
Command
Switch# show ip eigrp interfaces [interface] [as-number]
Switch# show ip eigrp neighbors [type|number|static]
Switch# show ip eigrp topology [autonomous-system-number |
[[ip-address] mask]]
Switch# show ip eigrp traffic [autonomous-system-number]

Route Summarization Example
The following example disables autosummarization and causes EIGRP to summarize network 10.0.0.0
out Ethernet interface 0 only:
interface Ethernet 0
ip summary-address eigrp 1 10.0.0.0 255.0.0.0
!
router eigrp 1
network 172.16.0.0
no auto-summary
You should not use the ip summary-address eigrp summarization command to generate the default
Note
route (0.0.0.0) from an interface because it creates an EIGRP summary default route to the null 0
interface with an administrative distance of 5. The low administrative distance of this default route can
cause this route to displace default routes learned from other neighbors from the routing table. If the
