+@node Starting and Stopping pimd
+@section Starting and Stopping pimd
+
+The default configuration file name of @command{pimd}'s is
+@file{pimd.conf}. When invocation @command{pimd} searches directory
+@value{INSTALL_PREFIX_ETC}. If @file{pimd.conf} is not there
+then next search current directory.
+
+@command{pimd} requires zebra for proper operation. Additionally
+@command{pimd} depends on routing properly setup and working
+in the network that it is working on.
+
+@example
+@group
+# zebra -d
+# pimd -d
+@end group
+@end example
+
+Please note that @command{zebra} must be invoked before @command{pimd}.
+
+To stop @command{pimd}. Please use @command{kill `cat
+/var/run/pimd.pid`}. Certain signals have special meanings to @command{pimd}.
+
+@table @samp
+@item SIGUSR1
+Rotate @command{pimd} logfile.
+@item SIGINT
+@itemx SIGTERM
+@command{pimd} sweeps all installed PIM mroutes then terminates properly.

+@node PIM Configuration
+
+@deffn Command {ip pim rp A.B.C.D A.B.C.D/M} {}
+In order to use pim, it is necessary to configure a RP for join
+messages to be sent to. Currently the only methodology to
+do this is via static rp commands. All routers in the
+pim network must agree on these values. The first ip address
+is the RP's address and the second value is the matching
+prefix of group ranges covered. This command is vrf aware,
+to configure for a vrf, enter the vrf submode.
+@end deffn
+
+@deffn Command {ip pim spt-switchover infinity-and-beyond} {}
+On the last hop router if it is desired to not switch over
+to the SPT tree. Configure this command. This command is
+vrf aware, to configure for a vrf, enter the vrf submode.
+#end deffn
+
+@deffn Comand {ip pim ecmp} {}
+If pim has the a choice of ECMP nexthops for a particular
+RPF, pim will cause S,G flows to be spread out amongst
+the nexthops. If this command is not specified then
+the first nexthop found will be used. This command
+is vrf aware, to configure for a vrf, enter the vrf submode.
+@end deffn
+
+@deffn Command {ip pim ecmp rebalance} {}
+If pim is using ECMP and an interface goes down, cause
+pim to rebalance all S,G flows aross the remaining
+nexthops. If this command is not configured pim only
+modifies those S,G flows that were using the interface
+that went down. This command is vrf aware, to configure
+for a vrf, enter the vrf submode.
+@end deffn
+
+@deffn Command {ip pim join-prune-interval (60-600)} {}
+Modify the join/prune interval that pim uses to the
+new value. Time is specified in seconds. This command
+is vrf aware, to configure for a vrf, enter the vrf submode.
+@end deffn
+
+@deffn Command {ip pim keep-alive-timer (31-60000)} {}
+Modify the time out value for a S,G flow from 31-60000
+seconds. 31 seconds is choosen for a lower bound
+because some hardware platforms cannot see data flowing
+in better than 30 second chunks. This comand is vrf
+aware, to configure for a vrf, enter the vrf submode.
+@end deffn
+
+@deffn Command {ip pim packets (1-100)} {}
+When processing packets from a neighbor process the
+number of packets incoming at one time before moving
+on to the next task. The default value is 3 packets.
+This command is only useful at scale when you can
+possibly have a large number of pim control packets
+flowing. This command is vrf aware, to configure for
+a vrf, enter the vrf submode.
+@end deffn
+
+@deffn Command {ip pim register-suppress-time (5-60000)} {}
+Modify the time that pim will register suppress a FHR
+will send register notifications to the kernel. This command
+is vrf aware, to configure for a vrf, enter the vrf submode.
+@end deffn
+
+@deffn Command {ip pim send-v6-secondary} {}
+When sending pim hello packets tell pim to send
+any v6 secondary addresses on the interface. This
+information is used to allow pim to use v6 nexthops
+in it's decision for RPF lookup. This command
+is vrf aware, to configure for a vrf, enter the vrf submode.
+@end deffn
+
+@deffn Command {ip pim ssm prefix-list WORD} {}
+Specify a range of group addresses via a prefix-list
+that forces pim to never do SM over. This command
+is vrf aware, to configure for a vrf, enter the vrf submode.
+@end deffn
+
+@deffn Command {ip multicast rpf-lookup-mode WORD} {}
+Modify how PIM does RPF lookups in the zebra routing table.
+You can use these choices:
+@table @lookup_modes
+@item longer-prefix
+Lookup the RPF in both tables using the longer prefix as a match
+@item lower-distance
+Lookup the RPF in both tables using the lower distance as a match
+@item mrib-only
+Lookup in the Multicast RIB only
+@item mrib-then-urib
+Lookup in the Multicast RIB then the Unicast Rib, returning first found.
+This is the default value for lookup if this command is not entered
+@item urib-only
+Lookup in the Unicast Rib only.
+@end table
+@end deffn
+
+@node PIM Interface Configuration
+@section PIM Interface Configuration
+
+PIM interface commands allow you to configure an
+interface as either a Receiver or a interface
+that you would like to form pim neighbors on. If the
+interface is in a vrf, enter the interface command with
+the vrf keyword at the end.
+
+@deffn {PIM Interface Command] {ip pim bfd} {}
+Turns on BFD support for PIM for this interface.
+@end deffn
+
+@deffn {PIM Interface Command} {ip pim drpriority (1-4294967295)} {}
+Set the DR Priority for the interface. This command is useful
+to allow the user to influence what node becomes the DR for a
+lan segment.
+@end deffn
+
+@deffn {PIM Interface Command} {ip pim hello (1-180) (1-180)} {}
+Set the pim hello and hold interval for a interface.
+@end deffn
+
+@deffn {PIM Interface Command} {ip pim sm} {}
+Tell pim that we would like to use this interface to form
+pim neighbors over. Please note we will *not* accept
+igmp reports over this interface with this command.
+@end deffn
+
+@deffn {PIM Interface Command} {ip igmp} {}
+Tell pim to receive IGMP reports and Query on this
+interface. The default version is v3. This command
+is useful on the LHR.
+@end deffn
+
+@deffn {PIM Interface Command} {ip igmp query-interval (1-1800)} {}
+Set the IGMP query interval that PIM will use.
+@end deffn
+
+@deffn {PIM Interface Command} {ip igmp query-max-response-time (10-250)} {}
+Set the IGMP query response timeout value. If an report is not returned
+in the specified time we will assume the S,G or *,G has timed out.
+@end deffn
+
+@deffn {PIM Interface Command} {ip igmp version (2-3)} {}
+Set the IGMP version used on this interface. The default value
+is 3.
+@end deffn
+
+@deffn {PIM Interface Command} {ip multicat boundary oil WORD} {}
+Set a pim multicast boundary, based upon the WORD prefix-list. If
+a pim join or IGMP report is received on this interface and the Group
+is denyed by the prefix-list, PIM will ignore the join or report.
+@end deffn
+
+@node PIM Multicast RIB insertion::
+@section PIM Multicast RIB insertion::
+
+In order to influence Multicast RPF lookup, it is possible to insert
+into zebra routes for the Multicast RIB. These routes are only
+used for RPF lookup and will not be used by zebra for insertion
+into the kernel *or* for normal rib processing. As such it is
+possible to create weird states with these commands. Use with
+caution. Most of the time this will not be necessary.
+
+@deffn {PIM Multicast RIB insertion} {ip mroute A.B.C.D/M A.B.C.D (1-255)} {}
+Insert into the Multicast Rib Route A.B.C.D/M with specified nexthop. The distance can be specified as well if desired.
+@end deffn
+
+@deffn {PIM Multicast RIB insertion} {ip mroute A.B.C.D/M INTERFACE (1-255)} {}
+Insert into the Multicast Rib Route A.B.C.D/M using the specified INTERFACE.
+The distance can be specified as well if desired.
+@end deffn
+
+@node Show PIM Information::
+@section Show PIM Information
+
+All PIM show commands are vrf aware and typically allow you to insert
+a specified vrf command if information is desired about a specific vrf.
+If no vrf is specified then the default vrf is assumed. Finally
+the special keyword 'all' allows you to look at all vrfs for the command.
+Naming a vrf 'all' will cause great confusion.

+The debugging subsystem for PIM behaves in accordance with how FRR handles debugging. You can specify debugging at the enable cli mode as well as the configure cli mode.
