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

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.
