◆
If an access-list is specified, it will be applied to received routes. If the received
routes are not matched in the access-list or the specified list does not exist, the
original distance value will be used.
Example
Console(config-router)#distance 90 10.1.1.64 255.255.255.255

Command Usage
◆
External routes are learned from an external autonomous system, and internal
routes from a peer within the local autonomous system. Local routes are those
configured with the
network command as a back door for the router or for the
networks being redistributed from another routing process.
◆
The route distance indicates the trustworthiness of a router. The higher the
distance the lower the trust rating. A distance of 255 means that the routing
source cannot be trusted and should be ignored.
◆
This command can be used to indicate that another protocol can provide a
better route to a node than that learned via eBGP, or to indicate that some
internal routes should be preferred by BGP.
