摘要： A static neighbor configured network device is configured with a static neighbor feature including a static neighbor list of network devices. The static neighbor configured network device is in a network segment that includes a dynamically configured network device. The static neighbor configured network device receives a multicast packet from the dynamically configured network device. It is determined if the dynamically configured network device is included in the static neighbor list of the static neighbor configured network device. The multicast packet is accepted if the dynamically configured network device is found in the neighbor list for the static neighbor configured network device. Also, adjacency for the static neighbor configured network device is not lost with any other currently adjacent network devices when the multicast packet is received.

摘要： In one embodiment, a method includes receiving a first link state initiation (HELLO) message from a first neighboring router. The HELLO message requests that a recipient node send a unique identifier for itself in a link state routing protocol. In response to receiving the first HELLO message, a first response message is sent that includes a first identifier from an identifier pool. The identifier pool contains for a local node a plurality of network identifiers that are unique among all nodes in the network that uses the link state routing protocol. A second HELLO message is received from a different second neighboring router. In response to receiving the second HELLO message, a second response message is sent that includes a different second identifier from the identifier pool.

摘要： Techniques for synchronizing routing data include determining whether conditions are satisfied for one-way transfer with an adjacent router. If it is determined that conditions are satisfied for one-way transfer of routing table data with the adjacent router, then a refresh-notice message is sent from the initiating router to the adjacent router. The refresh-notice message includes data that indicates a particular direction for transfer of routing table data. If the particular direction is inbound, then a copy of an adjacent routing table is received without sending a copy of the initiating router's own routing table. If the particular direction is outbound, then a copy of the own routing table is sent without receiving a copy of the adjacent routing table.

摘要： In one embodiment, a method includes receiving advertised costs to reach a destination address from neighbor routers. Based on the advertised costs, a minimum first cost to reach the destination address from the local router through the neighbors is determined. The first cost corresponds to a successor among the neighbors. Also determined is a minimum second cost of the advertised costs excluding only an advertised cost from the successor. The second cost corresponds to a second router. If it is determined that communication with the successor is interrupted, and the second cost is not less than the first cost, then it is determined whether the second cost is equal to the first cost. If so, then a data packet, which is directed to the destination address and received from a neighbor that is different from the second router, is forwarded to the second router.

摘要： In one embodiment, a method includes receiving authenticated site data that includes site ID data and address data. The site ID data indicates a unique site ID for each site among multiple sites for a first network that uses an internal routing protocol. Multiple edge sites of those sites are separate from each other and connected to a second network that is under separate administrative control of at least one different party. The address data indicates network addresses associated with each site of the plurality of sites. An external routing protocol message is discounted based on the authenticated site data.
