    Abstract: An example method includes receiving, by a first hop router (FHR) and from a source device, multicast stream data associated with a multicast stream, sending, from the FHR and to a rendezvous point (RP) using a Protocol Independent Multicast (PIM) protocol, one or more null register messages that are each associated with the multicast stream. Each of the one or more null register messages includes a source address and a group address that are collectively associated with the multicast stream, and each of the one or more null register messages further includes an indication to request that the RP refrain from sending any register-stop messages associated with the multicast stream to the FHR. The example method further includes, after sending the one or more null register messages that are each associated with the multicast stream, sending, to the RP, the multicast stream data in a non-encapsulated format.

    Abstract: Techniques are described for prioritized establishment of communication sessions. In one example, a network device parses a configuration file that defines a plurality of communication sessions of a routing protocol and includes priority values assigned to the communication sessions. The network device creates two or more lists of communication sessions for two or more of the priority values based on the configuration file, wherein each list of the two or more lists is created for a particular priority value of the priority values and defines one or more communication sessions of the plurality of communication sessions that are assigned the particular priority value. The network device then establishes the one or more communication sessions included in each list of the two or more lists according to an ordering based on the priority values associated with the two or more lists.

    Abstract: Techniques are described for enhancements to Protocol Independent Multicast (PIM) to enable a last hop router (LHR) to perform source discovery and directly build or join a source tree. According to the techniques of this disclosure, an LHR may be configured to receive a request to obtain multicast traffic corresponding to one or more multicast groups. The LHR may be configured to generate a source discovery join message including a request to join one or more multicast groups identified in the source discovery message and one or more source discovery flags. At least one of the one or more source discovery flags may indicate that the last hop router is interested in obtaining source information relating to at least one of the one or more multicast groups. The LHR may be configured to send, to a rendezvous point (RP) router in the network, the source discovery join message.

    Abstract: The potential problem of traffic loss during a period when a second PIM router is elected DR after a first PIM router (on the same PIM interface) was previously elected DR and is transiting multicast traffic, is solved by (1) configuring a first interval on a PIM interface for at least the first PIM router; (2) responsive to the PIM interface of the first PIM router booting up, (i) starting, by the first PIM router, a timer corresponding to the configured first interval, (ii) determining, by the first PIM router, whether or not it is the DR on the PIM interface, (iii) upon determining that the timer has expired, redetermining, by the first PIM router, whether or not it is the DR on the PIM interface, and (iv) responsive to a redetermination that the first PIM router is the DR on the PIM interface, (A) increasing, by the first PIM router, a DR priority value of the first PIM router to reduce a likelihood that another of the at least two PIM routers will replace the first PIM router as DR, and (B) sending on the PIM interface, by the first PIM router, a PIM HELLO message including the increased DR priority value.

The example method further includes, after sending the one or more null register messages that are each associated with the multicast stream, sending, to the RP, the multicast stream data in a non-encapsulated format.
