Displaying mrouted Routing Tables
mrouted contains three routing tables: the virtual interface table, the multicast routing table, and
the multicast routing cache table.
The virtual interface table displays the following topological information for each virtual interface:
• Physical and tunnel interfaces.
• The number of incoming and outgoing packets at each interface.
• The value of specific configuration parameters, such as metric and threshold.
An example virtual interface table is as follows:

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.
