Chapter 38 Configuring IP Unicast Routing

Configuring EIGRP

•Configuring EIGRP Route Authentication, page 38-41

•EIGRP Stub Routing, page 38-42

•Monitoring and Maintaining EIGRP, page 38-43

Note To enable EIGRP, the switch or stack master must be running the IP services feature set.

Default EIGRP Configuration

Table 38-7shows the default EIGRP configuration.

Table 38-7 Default EIGRP Configuration

	Feature	Default Setting
	Auto summary	Enabled. Subprefixes are summarized to the classful network
		boundary when crossing classful network boundaries.
	Default-information	Exterior routes are accepted and default information is passed
		between EIGRP processes when doing redistribution.
	Default metric	Only connected routes and interface static routes can be redistributed
		without a default metric. The metric includes:
		• Bandwidth: 0 or greater kb/s.
		• Delay (tens of microseconds): 0 or any positive number that is a
		multiple of 39.1 nanoseconds.
		• Reliability: any number between 0 and 255 (255 means
		100 percent reliability).
		• Loading: effective bandwidth as a number between 0 and 255
		(255 is 100 percent loading).
		• MTU: maximum transmission unit size of the route in bytes. 0 or
		any positive integer.
	Distance	Internal distance: 90.
		External distance: 170.
	EIGRP log-neighbor changes	Disabled. No adjacency changes logged.
	IP authentication key-chain	No authentication provided.
	IP authentication mode	No authentication provided.
	IP bandwidth-percent	50 percent.
	IP hello interval	For low-speed nonbroadcast multiaccess (NBMA) networks:
		60 seconds; all other networks: 5 seconds.
	IP hold-time	For low-speed NBMA networks: 180 seconds; all other networks:
		15 seconds.
	IP split-horizon	Enabled.
	IP summary address	No summary aggregate addresses are predefined.
	Metric weights	tos: 0; k1 and k3: 1; k2, k4, and k5: 0
	Network	None specified.
