(Optional) Configures a summary aggregate address
for a specified interface (not usually necessary if
auto-summary is enabled).
ip summary-address eigrp
autonomous-system-number address mask
Example:
Device(config-if)# ip summary-address
eigrp 109 192.161.0.0 255.255.0.0
Step 4
(Optional) Change the hello time interval for an
EIGRP routing process. The range is 1 to 65535
ip hello-interval eigrp
autonomous-system-number seconds
Step 5
seconds. The default is 60 seconds for low-speed
Example:
Device(config-if)# ip hello-interval
eigrp 109 10
NBMA networks and 5 seconds for all other
networks.
(Optional) Change the hold time interval for an
EIGRP routing process. The range is 1 to 65535
ip hold-time eigrp
autonomous-system-number seconds
Step 6
seconds. The default is 180 seconds for low-speed
Example:
Device(config-if)# ip hold-time eigrp
109 40
NBMA networks and 15 seconds for all other
networks.
Do not adjust the hold time without
consulting Cisco technical support.
Caution
(Optional) Disables split horizon to allow route
information to be advertised by a router out any
interface from which that information originated.
no ip split-horizon eigrp
autonomous-system-number
Example:
Device(config-if)# no ip
split-horizon eigrp 109
Step 7
Returns to privileged EXEC mode.end
Example:
Device(config)# end
Step 8
Displays which interfaces EIGRP is active on and
information about EIGRP relating to those interfaces.
show ip eigrp interface
Example:
Device# show ip eigrp interface
Step 9
(Optional) Saves your entries in the configuration
