Default EIGRP Configuration
Ta ble 42-7 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 inf
ormation is passed between EIGRP processes
when doing redistribution.
Default metric Only connected routes and interface static rou
tes 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 adjacenc
y 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
netw
orks: 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 addre
sses are predefined.
Metric weights tos: 0; k1 and k3: 1; k2, k4, and k5: 0
