[. . . ] Example host1:boston(config)#router pim · · · Use the no version to remove PIM from the VR. See router pim. Resetting PIM Counters and Mappings You can use the clear ip pim commands to reset PIM counters and mappings. clear ip pim auto-rp · · Use to clear the group-to-RP router mappings that the router learned through auto-RP. Specify the IP address of an RP to clear the group-to-RP mappings for a particular RP. If you do not specify an IP address, the router clears the group-to-RP mappings on all RP routers learned through auto-RP. Example host1#clear ip pim auto-rp 192. 34. 56. 7 · · · There is no no version. See clear ip pim auto-rp. clear ip pim interface count 106 Copyright © 2010, Juniper Networks, Inc. Chapter 3: Configuring PIM for IPv4 Multicast · Use to clear the counters for multicast packet statistics on all interfaces or a specified interface. Specify an interface type and specifier, such as atm 3/0, to clear the counters on that interface. For details about interface types and specifiers, see Interface Types and Specifiers in JunosE Command Reference Guide. If you do not specify an interface, the router clears the counters on all interfaces. Example host1#clear ip pim interface atm 3/0. 5 count · · · · · There is no no version. See clear ip pim interface count. clear ip pim remote-neighbor count · Use to clear the counters for remote neighbor statistics on all interfaces or the specified interface. Specify the IP address of an interface to clear the counters for that interface. If you do not specify an interface, the router clears the counters on all interfaces. Example host1#clear ipv6 pim remote-neighbor 1001::1 count · · · · · There is no no version. See clear ip pim remote-neighbor count. Monitoring PIM You can display information about PIM events and parameters. Monitoring PIM Events You can use the debug PIM commands to view information about PIM events. debug ip pim · · · · Use to show information about the selected event. To control how much information to display, specify a verbosity level. Example host1#debug ip pim events severity 1 verbosity low · · Use the no version to disable the display. See debug ip pim. undebug ip pim Copyright © 2010, Juniper Networks, Inc. 107 JunosE 11. 2. x Multicast Routing Configuration Guide · Use to turn off the display of information previously enabled with the debug ip pim command. Example host1#undebug ip pim events · · · There is no no version. See undebug ip pim. Monitoring PIM Settings You can use the show ip pim commands to display information about PIM settings. [. . . ] To display all group-to-RP mappings that the router has recorded, specify the mapping keyword.
