Multicast

  • Limit unknown multicast traffic on multicast-router interfaces (EX Series)—Limit the flooding of L2 multicast streams to multicast-router interfaces on a per VLAN or bridge domain level. Limit unknown multicast traffic by restricting the flooding of multicast data to the multicast-router interface based on IGMP or Multicast Listener Discovery (MLD) join messages to efficiently utilize bandwidth. To enable this feature, use the no-flood-to-multicast-router-interfaces configuration statement.

    In an Ethernet VPN (EVPN) environment, prevent unknown multicast streams from being sent to EVPN Provider Edges (PEs) by sending EVPN Type-3 routes with multicast extended community flags and IGMP/MLD snooping proxy flags set.

    [See Restrict Flooding of Unknown Multicast Traffic to the Multicast-router Interface in an L2 environment.]

  • Enhancement to L3 multicast operational commands (EX4100-24T, EX4300-MP, EX4400-24MP, EX4400-24P, EX4400-48F, EX4400-48MP, EX4650, MX960, QFX5120-32C, QFX5120-48T, QFX5120-48T-VC, QFX5120-48Y, QFX5120-48Y-VC, and QFX5120-48YM)—The show instance command now extends to all routing instances for the following commands. Previously, only specific Protocol Independent Multicast (PIM)-enabled routing instances were displayed.

    • show pim join instance all

    • show pim rps instance all

    • show pim statistics instance all

    • show multicast route instance all

    • show multicast statistics instance all

    The show pim statistics output will display V2 Sparse Join and V2 Sparse Prune counters.

    The show igmp statistics output will also display the V1/V2/V3 Membership Query field.
