On a PIM-DM network, the Device waits for an ACK message from the upstream device after it sends a Graft message. To check the PIM-DM Graft messages that have been sent but unacknowledged, run the display pim grafts command.
Example
The actual command output varies according to the device. The command output here is only an example.
# Display unacknowledged PIM-DM Graft messages in the public network instance.
