# Monitoring IPv6 Multicast Protocols Enabled on the Router

#### Purpose

Display information about multicast protocols enabled on the router.

#### Action

To display information about enabled multicast protocols:

    host1:2#show ipv6 multicast protocols
    Multicast protocols:

    Protocol Pim
        Type: Sparse
        Interfaces: 1 registered, 1 owned
        Registered interfaces:
            ATM2/1.103 (21:2:2:22::1:2/60) owner Pim
    Protocol Mld
        Type: Local
        Interfaces: 1000 registered, 1000 owned
        Registered interfaces:
            ATM2/0.131 (31:2:2:22::2:2/604) local Mld owner Mld
                Admission-bandwidth 2000000/10000000 bps
                QoS Adjust 2000 bps
            ATM2/0.132 (31:2:2:22::2:3/60) local Mld owner Mld
                Admission-bandwidth 0/10000000 bps
                QoS Adjust 0 bps
            ATM2/0.133 (31:2:2:22::2:4/60) local Mld owner Mld
                Admission-bandwidth 8000000/10000000 bps, 2 Blocked OIFs
                QoS Adjust 0 bps
    ...
    Count: 2  protocols

#### Meaning

Table 22 lists the show ipv6 multicast protocols command output fields.

Table 22: show ipv6 multicast protocols Output Fields

Field Name | Field Description
--- | ---
Protocol | Name of the multicast protocol
Type | Mode of the multicast protocol: For PIM—Sparse For MLD—Local
Interfaces | registered—Number of interfaces on which the protocol is configured owned—Number of interfaces that a protocol owns. If you configure only MLD on an interface, MLD owns the interface. However, if you configure MLD and PIM on the same interface, PIM owns the interface.
Registered interfaces | Includes the following information about interfaces on which the protocol is configured: Types and identifiers of interfaces. For details about interface types and specifiers, see Interface Types and Specifiers in JunosE Command Reference Guide . Protocols configured on the interface and the protocol that owns the interface. If you configure only MLD on an interface, MLD owns the interface. However, if you configure MLD and PIM on the same interface, PIM owns the interface. Admitted bandwidth / configured admission bandwidth (in bps) Number of blocked OIFs QoS adjustment bandwidth (in bps)
Count | Number of multicast protocols on the virtual router
