Method of effecting dynamic management of path or routing information without requiring an internetworking operation for routing
First Claim
1. A method for transferring path or routing information of a first internetworking equipment, which is connected to at least one alternative internetworking equipment by means of a circuit, and for communicating said path or routing information between computer networks respectively coupled to said first internetworking equipment and said alternative internetworking equipment, said method comprising:
- an exchange process for exchanging said path or routing information with said alternative internetworking equipment in response to a request for transmission of said path or routing information, said path or routing information being transmitted also when data other than said path or routing information is transmitted.

Abstract
In a method for transferring path information of an internetworking equipment (router), the router is connected to an alternative router or routers by means of a circuit of an ISDN, whereby routing information between networks is communicated. When activated, the first router is connected to a circuit in response to a request for routing information transmission, and transmits all pieces of routing information to the alternative router(s). When it is connected to the circuit in response to a request for some other transmission than the routing information transmission, the first router exchanges the routing information with the alternative router(s). When the routing information is changed, the first router is connected to the circuit in response to a request for routing information transmission, and transmits the routing information to the other router(s) without executing periodical updating.
