Operational note for PIM-SM over IPv6

The following are operational considerations when deploying PIM-SM over IPv6:
  • You can only configure PIM-SM if you configure the spbm_config_mode boot flag to false

  • The following HELLO messages options are not supported:
    • GENid

    • DR priority

    • LAN-PRUNE delay

    • T-bit

  • IPv6 multicast is not supported over SPBM

  • IPv6 multicast routing is not virtualized, it is supported only on GRT

  • IPv6 multicast configuration on SMLT VLAN is not supported. vIST peers cannot form PIM-SM over IPv6 neighbor adjacencies. Senders and receivers on the vIST peers (SMLT and non-SMLT) cannot communicate. MLT and LACP is supported.

  • The switch does not support the following features:
    • Static entries

    • Bootstrap message (BSR)

    • Anycast RP

    • Virtual PIM neighbors

    • Fast join prune

    • Software forwarding

    • Passive PIM interfaces

    • IP mroute stream limit

    • Bidirectional PIM

    • Multicast Border Router (PMBR)

    • VRF support for PIM (GRT only)

    • IGMP and PIM mtrace capability

    • High Availability (HA)
