"distance" on page 1027

Administrative distance is used by the routers to select the preferred

path when there are two or more different routes to the same

destination from two different routing protocols. A smaller

administrative distance indicates a more reliable protocol.

An access list can be used to filter networks according to the IP address

of the router supplying the routing information. For example, to filter

out unreliable routing information from routers not under your

administrative control.

The administrative distance is applied to all routes learned for the

specified network.

These parameters are displayed in the web interface:

Distance – Administrative distance for external routes. External routes

are routes for which the best path is learned from a neighbor external

to the local RIP autonomous system. Routes with a distance of 255 are

not installed in the routing table. (Range: 1-255)

IP Address – IP address of a route entry.

Subnet Mask – This mask identifies the host address bits used for

associated routing entries.

ACL Name – Name of the access control list. Any type of ACL can be

specified, including standard or extended IP ACLs and MAC ACLs.
