摘要： A method for convergence of multicast traffic in response to a topology change. The method includes, in response to a change in a multicast topology, redirecting multicast traffic through a network device of a plurality of network devices in the multicast topology and determining a querier status of the network device. The method also includes flooding the multicast traffic through an interface to the network device to facilitate convergence of the multicast traffic. The interface is a connecting point between the network device and another network device of the plurality of network devices.

摘要： A method for multicast routing may include receiving, at a router of a receiving multicast domain, a data packet from a forwarding multicast domain. The method may further include configuring the router to operate as if a multicast forwarding information base entry is directly connected, and configuring the router with a reverse path forwarding override with source discovery such that a path used by multicast traffic is different from a path used for unicast traffic.

摘要： One example includes a network device. The network device includes a plurality of ports and application specific logic. The application specific logic is to receive a multicast packet including client data and a header, the header including a route group identifier. The application specific logic is to determine a group of routed interfaces and an associated set of ports for each routed interface based on the route group identifier. The application specific logic is to replicate the client data to provide a packet for each routed interface and transmit, for each routed interface, the packet for the routed interface to the associated set of ports for the routed interface.

摘要： Examples described herein provide for generating a multicast consumer search request from a request node in the network. The request is then routed to the interconnected nodes and received at a target node having a directly-connected multicast consumer. Identification information associated with the directly-connected multicast consumer is forwarded from the target node back to the request node.

摘要： Network service insertion includes determining a tunnel interface corresponding to a service entity to which an incoming packet is to be directed, the tunnel interface being determined based on software defined network (SDN) flow rules. Further, the incoming packet can be encapsulated based on a tunnel configuration corresponding to the tunnel interface to generate an encapsulated packet such that the encapsulated packet includes media access control (MAC) address headers and a virtual local area network (VLAN) tag associated with the incoming packet. The encapsulated packet can be sent to the service entity through the tunnel interface for network service insertion.

摘要： Methods for controlling a Designated Forwarder (DF) election in a multicast network are described herein. The multicast network includes a plurality of multicast network devices, including a first network device and a second network device. A Designated Forwarder is determined. It is determined whether to initiate a Designated Forwarder election based on a comparison of a metric measuring a distance to a Rendezvous Point Address from a first network device and a metric measuring the distance to the Rendezvous Point Address from the second network device.
