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 63 lists the show ipv6 multicast protocols command output fields.

Table 63: 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
