19.3.4.6PIM-DM Troubleshooting Help

In configuring and using PIM-DM protocol, the PIM-DM protocol may fail to run properly due to reasons such as physical connection failure or wrong configurations. The user should ensure the following:

—Good condition of the physical connection.

—All interface and link protocols are in the UP state (use “show interface” command).

—Next, enable PIM-DM protocol on the interface (use the “ip pim dense-mode” command).
