An administrative distance is a rating of the trustworthiness of a routing information source, such as an
individual switch or a group of switches. Numerically, an administrative distance is an integer from 0 to
255. In general, the higher the value, the lower the trust rating. An administrative distance of 255
means the routing information source cannot be trusted at all and should be ignored.
When this command is configured, it is applied when a network is being inserted into the routing table It
filters routing updates according to the IP address of the switch that supplies the routing information. It
could be used, for example, to filter possibly incorrect routing information from switches that are not
under your administrative control. The optional access list name is used to filter router entries in routing
update.
Examples
The following is sample output from the distance command:
router rip
