    Monitoring Active Data MDTs for IPv4

    Purpose

    Display information about active data MDTs. Use the following keywords to display the required information:

    • sender—To display information about data MDTs on which the provider edge transmits data
    • receiver—To display information about data MDTs on which the provider edge receives data
    • group—To display information about an IP PIM group address pool
    • summary—To display a summary of configuration for each data MDT
    • count—To display the number of data MDTs

    Action

    To display information about a data MDT sender:

    host1:PE1#show ip pim data-mdt 225.1.1.1
    PE11 - Sender
      C-SG: 10.11.0.100, 225.1.1.1
      P-SG: 1.1.1.1, 235.0.1.1
      MTI: TUNNEL gre:mvpn-dynamic-1
        Data rate/Threshold: 10012/500 Kbps
        Time until next MDT Join TLV: 25 seconds

    To display information about a data MDT receiver:

    host1:PE1#show ip pim data-mdt 225.2.2.2
    PE31 - Receiver
      C-SG: 10.13.0.100, 225.2.2.2
      P-SG: 3.3.3.3, 235.0.1.1
      MTI: TUNNEL gre:mvpn-dynamic-3
        Time until MDT Join TLV expires: 29 seconds

    To display a summary of data MDT senders:

    host1:PE1#show ip pim data-mdt senders summary
    
    VRF    S/R       C-Group     C-Source      P-Group    P-Source           MTI           
    ----   -------   ---------   -----------   ---------  --------   ---------------
    PE11   Sender   225.1.1.1   10.11.0.100    235.0.1.1  1.1.1.1    TUNNEL gre:mvpn-dynamic-1
    PE12   Sender   225.1.1.1   10.12.0.100    235.0.1.2  1.1.1.1    TUNNEL gre:mvpn-dynamic-2
    Counts: 2 senders, 0 receivers, total 3.

    To display the number of data MDT senders and receivers:

    host1:PE1#show ip pim data-mdt count
    Counts: 2 senders, 1 receivers, total 3.
