1. A method for configuring dynamic interfaces, comprising the steps of:
- saving routing configuration information using symbolic names;
determining when a symbolically named interface becomes active;
resolving the symbolic name to an operational IP address for routing and creating dynamic routing protocol packets; and
thereafter communicating said dynamic routine protocol packets over said dynamic interface.

Abstract
Dynamic interfaces such as PPP interfaces are configured by (1) saving routing configuration information using symbolic names; (2) determining when a symbolically named interface becomes active; (3) resolving the symbolic name to an operational IP address for routing and RIP traffic; and thereafter (4) communicating dynamic protocol packets over the dynamic interface.

2. A method for configuring dynamic interfaces for routing and creating dynamic routing protocol packets, comprising the steps of:
-
initializing a configuration table with entries for each of one or more active interfaces and associated interface configuration information;
initializing a route table with an entry for each active route;
responsive to a request to activate a dynamic interface, said request including a logical name;
establishing a physical connection to said interface; and
negotiating an IP address defining said interface;
generating a message packet including said logical name and said IP address;
responsive to said message packet, obtaining from said configuration table configuration information associated with a local interface name matching said logical name;
adding a route entry to said route table including information from said configuration table and said message packet associated with said IP address; and
communicating routing protocol packets over the dynamic interface configured with said IP address and said configuration information. - View Dependent Claims (3, 4)

5. A system for configuring dynamic interfaces, comprising:
-
an interface configuration table for saving routing configuration information using symbolic names;
a routing table for storing the configuration information for at least one route identified by an operational IP address;
a configuration control module responsive to activation of a symbolically named interface for resolving the symbolic name to an operational IP address for said dynamic interface for routing and creating dynamic routing protocol packets;
said configuration control module updating said routing table with a route entry including said operational IP address for said dynamic interface; and
a router module responsive to said route entry for communicating said dynamic routing protocol packets over said dynamic interface.
