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.

A system for optimizing the performance of a network. In an illustrative embodiment, the system includes a memory containing one or more data structures data structures. A first module determines transit-only information. A second module selectively omits the transit-only information from the one or more data structures. In a more specific embodiment, the one or more data structures include one or more tables. The transit-only information includes interface Internet Protocol (IP) addresses associated with network interfaces that are transit-only interfaces. The route information may include network topology information. The one or more tables may include a network topology table. Plural routers positioned in the network incorporate one or more instances of the system. The routers may employ one or more routing protocols, such as include Enhanced Interior Gateway Routing Protocol (EIGRP) or Routing Information Protocol (RIP).

Techniques for sending data in a packet-switched communications network include determining multiple subsets of adjacent network nodes of the network. The adjacent network nodes communicate without intervening network nodes with a particular network node through an interface on the particular network node. Each subset includes multiple adjacent network nodes. Subset definition data is sent through the interface. The subset definition data indicates which adjacent network nodes belong to which subset. Data for fewer than all adjacent network nodes in all subsets are sent by including, in a multicast data packet sent over the interface with a multicast destination address, subset identifier data that indicates a particular subset. When such data is received by a node, it is discarded unless the subset identifier matches the receiving node's subset identifier. Among other effects, this allows routing messages to be more efficiently sent to better performing neighboring network nodes.

A wallet includes a first shell with one or more openings on a shell perimeter adapted to clip one or more objects to the one or more openings; and a second shell coupled to the first shell, the second shell including a storage compartment; and first and second rails on each side of the second metal shell to slideably receive one or more cards in the storage compartment.

A wallet includes a first metal shell with one or more openings on a shell perimeter adapted to clip one or more objects to the one or more openings; a second metal shell coupled to the first shell with a storage compartment therebetween; and securing a soft material to the first and second metal shells, wherein the soft material comprises compartments to store cards or money therein.
