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.
