Cisco Systems 3750E manual Configuring Eigrp Interfaces, No auto-summary, Ip summary-address eigrp

Chapter 38 Configuring IP Unicast Routing

Configuring EIGRP

	Command	Purpose
Step 6
	metric weights tos k1 k2 k3 k4 k5	(Optional) Adjust the EIGRP metric. Although the defaults have
		been carefully set to provide excellent operation in most networks,
		you can adjust them.
		Caution Setting metrics is complex and is not recommended
			without guidance from an experienced network
			designer.
Step 7
	offset list [access-list number name] {in out}	(Optional) Apply an offset list to routing metrics to increase
	offset [type number]	incoming and outgoing metrics to routes learned through EIGRP.
		You can limit the offset list with an access list or an interface.
Step 8
	no auto-summary	(Optional) Disable automatic summarization of subnet routes into
		network-level routes.
Step 9
	ip summary-address eigrp	(Optional) Configure a summary aggregate.
	autonomous-system-number address mask
Step 10
	end	Return to privileged EXEC mode.
Step 11
	show ip protocols	Verify your entries.
Step 12
	show ip protocols	Verify your entries.
		For NSF awareness, the output shows:
		*** IP Routing is NSF aware ***
		EIGRP NSF enabled
Step 13
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

Use the no forms of these commands to disable the feature or return the setting to the default value.

Configuring EIGRP Interfaces

Other optional EIGRP parameters can be configured on an interface basis.

Beginning in privileged EXEC mode, follow these steps to configure EIGRP interfaces:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	interface interface-id	Enter interface configuration mode, and specify the Layer 3
		interface to configure.
Step 3
	ip bandwidth-percent eigrp percent	(Optional) Configure the percentage of bandwidth that can
		be used by EIGRP on an interface. The default is 50 percent.
Step 4
	ip summary-address eigrp	(Optional) Configure a summary aggregate address for a
	autonomous-system-number address mask	specified interface (not usually necessary if auto-summary is
		enabled).
