D Commands
This chapter describes the Cisco NX-OS Enhanced Interior Gateway Routing Protocol (EIGRP) commands that begin with D.
default-information originate (EIGRP)
To generate a default route into the Enhanced Interior Gateway Routing Protocol (EIGRP), use the default-information originate command. To disable this feature, use the no form of this command.
default-information originate [always] [route-map map-name]
no default-information originate
Syntax Description
Command Default
Disabled
Command Modes
Address-family configuration mode
Router configuration mode
Router VRF configuration mode

Usage Guidelines
This command requires the LAN Base Services license.
Examples
This example shows how to originate a default route (0.0.0.0/0) to all routes that pass the Condition route map:
switch(config)# router eigrp 201
switch(config-router)# address-family ipv4 unicast
switch(config-router-af)# default-information originate route-map Condition

default-metric (EIGRP)
To set metrics for an Enhanced Interior Gateway Routing Protocol (EIGRP), use the default-metric command. To remove the metric value and restore the default state, use the no form of this command.
default-metric bandwidth delay reliability loading mtu
no default-metric
Syntax Description
Command Default
bandwidth: 100000
delay: 100 (tens of microseconds)
reliability: 255
loading: 1
Command Modes
Address-family configuration mode
Router configuration mode
Router VRF configuration mode

6.0(2)N1(1) |
This command was introduced. |
Usage Guidelines
Use the default-metric command with the redistribute command to use the same metric value for all redistributed routes. A default metric helps to solve the problem of redistributing routes with incompatible metrics. Whenever external metrics do not convert to EIGRP metrics, you can use a default metric to provide a reasonable substitute to the external metric and enable the redistribution to proceed.
This command requires the LAN Base Services license.
Examples
This example shows how to take redistributed Routing Information Protocol (RIP) metrics and translate them into EIGRP metrics with the following values: bandwidth = 1000, delay = 100, reliability = 250, loading = 100, and MTU = 1500.
switch(config)# router eigrp 1
switch(config-router)# address-family ipv4 unicast
switch(config-router-af)# redistribute rip 100 route-map FilterRIP
switch(config-router-af)# default-metric 1000 100 250 100 1500
switch(config-router-af)#

distance (EIGRP)
To allow the use of two administrative distances (internal and external) for the Enhanced Interior Gateway Routing Protocol (EIGRP) that could provide a better route to a node, use the distance command. To return to the default setting, use the no form of this command.
distance internal-distance external-distance
no distance
Syntax Description
Command Default
internal-distance: 90
external-distance: 170
Command Modes
Address-family configuration mode
Router configuration mode
Router VRF configuration mode

6.0(2)N1(1) |
This command was introduced. |
Usage Guidelines
An administrative distance is a rating of the trustworthiness of a routing information source, such as an individual router or a group of routers. Numerically, an administrative distance is an integer from 0 to 255. In general, a higher value indicates a lower trust rating. An administrative distance of 255 means that the routing information source cannot be trusted and should be ignored.
Use the distance command if another protocol is known to provide a better route to a node than was actually learned through the external EIGRP or some internal routes should be preferred by EIGRP.
This command requires the LAN Base Services license.
Examples
This example shows how to set the administrative distance of all EIGRP 1 internal routes to 80 and all EIGRP external routes to 130:
switch(config)# router eigrp 1
switch(config-router)# distance 80 130
