    Monitoring PIM Interfaces for IPv6

    Purpose

    Display information about PIM interfaces. Specify no keywords or variables to view information about all PIM interfaces. You can specify the detail keyword to view detailed information for all PIM interfaces or for a specified PIM interface. You can specify the summary keyword to view the number of configured, enabled, and disabled PIM sparse-mode interfaces. You can specify the count keyword to view the number of multicast packets that the interface has sent and received.

    Note: Provide an interface type and specifier (such as atm 3/0) to display information about that interface only. For details about interface types and specifiers, see Interface Types and Specifiers in JunosE Command Reference Guide.

    Action

    To display information for all PIM interfaces, or for a specified PIM interface:

    host1# show ipv6 pim interface
    
    PIM Interface Table
    Interface Addr Interface   State Ver Mode    Nbr    Hello  J/P    DR    DR Addr   JoinFilter
                                                 Count  Intvl  Intvl  Pri
    101::1         ATM2/0.100  Up     2  Sparse   1      30    150     5    101::2    -
    102::1         ATM2/0.101  Up     2  Sparse   1      30    100     2    102::2    silver
    103::1         ATM3/0.102  Up     2  Sparse   1      30    100     2    103::1    gold
    

    To display the number of configured, enabled, and disabled PIM sparse-mode interface:

    host1#show ipv6 pim interface summary
    PIM Interface Summary
      SM:    0, 0 enabled, 0 disabled

    To display the number of multicast packets that the interface has sent and received:

    host1#show ipv6 pim interface count
    PIM Interface Count
    Interface Addr  Interface Name       ControlPktCount In|Out
                                         Hello     JoinPrune  Assert
    ::107:84        ATM3/0.20             0         0           0
                                          0         0           0

    Meaning

    Table 1 lists the show ipv6 pim interface command output fields.
