METHOD AND APPARATUS TO ENABLE AN IPe DOMAIN THROUGH EIGRP
First Claim
1. A method comprising:
- receiving, at a connection node in a communications network, a network routing address for transmitting data packets from a source node to a destination node;
comparing a cost of selecting said network routing address with costs of preexisting entries of said network routing addresses in a routing table stored at said connection node;
selecting the network routing address comprising the lowest cost;
determining which selected neighbor connection nodes send a longest summary route covering a path to said destination node; and
sending an update of the longest summary route of the network routing address to said selected neighbor connection nodes.

Abstract
In one embodiment, a system, method, and apparatus for preventing excessive transmission of routing information in a communications network occurs by receiving a network routing address at a connection node in a communications network, the network routing address allowing the transmission of data packets from a source node to a destination node in the communications network; determining a longest summary route covering a path to the destination node; creating a list comprising a summary of all neighbor connection nodes of the connection node; and transmitting an update of the longest summary route of the network routing address towards all neighbor nodes advertising a destination address comprising a shorter address prefix, wherein the transmitting process occurs sequentially beginning with a first neighbor connection node entered in the list.

10. An apparatus comprising:
-
means for receiving a network routing address at a connection node in a communications network, the network routing address allowing the transmission of data packets from a source node to a destination node in said communications network; means for determining a longest summary route covering a path to said destination node; means for creating a list comprising a summary of all neighbor connection nodes of said connection node; and means for transmitting an update of the longest summary route of the network routing address towards all neighbor nodes advertising a destination address comprising a shorter address prefix, wherein the transmitting process occurs sequentially beginning with a first neighbor connection node entered in said list. - View Dependent Claims (11, 12, 13, 14, 15)

16. An apparatus comprising:
-
a connection node located in a communications network and configured to receive a network routing address for transmitting data packets from a source node to a destination node in said communications network; a routing table stored at said connection node configured to compare a cost of selecting said network routing address with costs of preexisting entries of said network routing addresses in said routing table; and a processor operatively connected to said connection node, wherein said processor is adapted to select the network routing address comprising the lowest cost, to determine which selected neighbor connection nodes send a longest summary route covering a path to said destination node, and to send an update of the longest summary route of the network routing address to said selected neighbor connection nodes. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
