Configuring mrouted
Displaying mrouted Routing Tables
Chapter 2 39
The multicast routing table displays connectivity information for each
subnet from which a multicast datagram can originate.
The multicast routing cache table is a duplicate copy of the kernel
forwarding cache table. It contains the status information for multicast
destination group-origin subnet pairs.
mrouted retrieves these tables by sending an appropriate signal to the
mrouted daemon. mrouted responds to the following signals:
HUP Restarts mrouted. The configuration file is reread each
time this signal is evoked.
INT Terminates mrouted by sending messages to all
neighboring routers.
TERM The same as INT.
USR1 Defined as signal 16, dumps the internal routing tables
(virtual interface table and multicast routing table) to
/usr/tmp/mrouted.dump.
USR2 Defined as signal 17, dumps the multicast routing
cache tables to /usr/tmp/mrouted.cache.
QUIT Dumps the internal routing tables (virtual interface
table and multicast routing table) to stderr (only if
mrouted was invoked with a nonzero debug level).
You can send signals to mrouted by issuing the HP-UX kill command at
the HP-UX prompt. For example:
kill -USR1
pid
where
pid
is the process ID of the mrouted daemon.
For more information on the routing tables, type man 1M mrouted at the
HP-UX command prompt, and see the EXAMPLE section.
