distance
Use the command distance to define an administrative distance for a protocol
(RIP, OSPF, etc) or the routes that fall in the range of the specified networks-
prefix. Use the no form of the command to remove the distance configuration and
then the distance will go back to the default.
distance DISTANCE [NETWORK-PREFIX/PREFIX-LENGTH]
no distance DISTANCE [NETWORK-PREFIX/PREFIX-LENGTH]
Default No static routes are established.
The table below shows the default distance of protocols:
Command Mode Router configuration
Usage Guideline This command is only used for routing protocols (RIP, OSPF). The distance
command of a static route uses the ip route command on page 319 with the
distance option. The distance of local interface can not be configured.
Numerically, an administrative distance is an integer from 1 to 255. In general,
the higher the value is, the lower the trust rating is. An administrative distance of
255 means that the routing information source cannot be trusted at all and should
be ignored.
Use the distance command to set the administrative distance for all the routes
that fall in the range of the specified networks-prefix. That is, if the route is in the
range of the networks-prefix, the distance specified for the network prefix will be
applied to this route.
Syntax Description
DISTANCE An administrative distance. The default administrative distance for a static route
is 1. The range of distance is 1 to 255. The lower value represents a better route.
NETWORK-PREFIX/
PREFIX-LENGTH
(Optional) The network prefix and the prefix length specify the destination
network. The Network-Prefix/Prefix-Length parameter is not supported for OSPF.
Connected interface 0 The administrative distance of a
Connected interface.
Static route 1 The administrative distance of a
Static route.
Open Shortest Path First
(OSPF)/OSPF6
110 The administrative distance of an
OSPF route.
Routing Information Protocol
(RIP)/RIPng
120 The administrative distance of a RIP
route.
Unknown 255 The administrative distance of an
unknown protocol route.
