    摘要: Described is a method for statically or dynamically enabling a DVMRP router in a DVMRP domain to perform a reverse path forwarding check for an external source. A route report is generated for each known external source and injected into the DVMRP domain. Each route report includes routing information for a respective one of the known external sources. In one embodiment, the route report is generated for each network listed in a unicast routing table maintained on a DVMRP multicast border router and each route report includes unicast routing information for each of the networks and an indicator designating that the routing information is derived from unicast routing information. In another embodiment, if it is determined that routing information for an external source of multicast traffic received at a DVMRP border router is not available, the route report is generated at that time and includes a predetermined metric value.

    摘要: A method and apparatus is disclosed which enables detection of undesired packets received at a device in a network, where the device is a member of a group of devices in the network. A registration table stores transform identifiers for each member of a group and controls the forwarding of the transform identifiers to the members of the group as members are added and deleted. A transform identifier indicates a format or transformation of a packet transmitted by an associated member. The transform identifier can therefore be used at a receiving device to distinguish between transmissions by different members of the group, thereby enabling the receiving device to extract sequence information associated with the member from the packet. The sequence information can be compared against an expected sequence number for the member to determine whether the packet is an undesirable or rogue packet.

    摘要: Method and apparatus that enable secure transmission of data in a scalable private network are described. Each station that is to be part of a private network registers with a key table. A group security association associated with the private network is forwarded to each trusted ingress and egress point that communicates with each member of the private network. When a member of the private network seeks to communicate with another member, it simply forwards the communication to the trusted ingress point. The trusted ingress point uses the security association associated with the private network to transform the communication and forwards the transformed communication through other intermediate stations in the network until it reaches a trusted egress point. The trusted egress point uses the stored security association to decode the transformed communication and forwards the communication to the appropriate destination. The ingress and egress points may be any points in the network, including customer edge devices, provider edge devices, or some combination thereof.

    摘要: A method and apparatus for authorizing forwarding states in a Layer 2 device of a multicast system includes a forwarding table for use in forwarding communications to group members over interfaces of the Layer 2 device. According to one aspect of the invention, associated with the forwarding state is an authorization flag. The authorization flag signals whether or not the forwarding state is an authorized forwarding state over which multicast communications may be transferred. The Layer 2 device snoops authorization communications between a host and a layer 3 device, and updates the forwarding table authorization flags in response to these communications.
