mrinfo - Displays configuration info from a multicast
/usr/sbin/mrinfo [ -d debug_level ] [ -r retry_count ] [
-t timeout_count ] multicast_router
mrinfo attempts to display the configuration information
from the multicast router multicast_router.
mrinfo uses the ASK_NEIGHBORS IGMP message to the speci-
fied multicast router. If this multicast router responds,
the version number and a list of their neighboring multi-
cast router addresses is part of that response. If the
responding router has a recent multicast version number,
then mrinfo requests additional information such as met-
rics, thresholds, and flags from the multicast router.
Once the specified multicast router responds, the configu-
ration is displayed to the standard output.
"-d" option sets the debug level. When the debug level is
greater than the default value of 0, addition debugging
messages are printed. Regardless of the debug level, an
error condition, will always write an error message and
will cause mrinfo to terminate. Non-zero debug levels
have the following effects:
packet warnings are printed to stderr.
all level 1 messages plus notifications down net-
works are printed to stderr.
all level 2 messages plus notifications of all
packet timeouts are printed to stderr.
"-r retry_count" sets the neighbor query retry limit.
Default is 3 retry.
"-t timeout_count" sets the number of seconds to wait for
a neighbor query reply. Default timeout is 4 seconds.
127.148.176.10 (mbone.phony.dom.net) [version 3.3]:
127.148.176.10 -> 0.0.0.0 (?) [1/1/querier]
127.148.176.10 -> 127.0.8.4 (mbone2.phony.dom.net) [1/45/tunnel]
127.148.176.10 -> 184.108.40.206 (momoney.com) [1/32/tunnel/down]
127.148.176.10 -> 220.127.116.11 (mbone.dipu.edu) [1/32/tunnel]
For each neighbor of the queried multicast router, the IP
of the queried router is displayed, followed by the IP and
name of the neighbor. In square brackets the metric (cost
of connection), the treashold (multicast ttl) is dis-
played. If the queried multicast router has a newer ver-
sion number, the type (tunnel, srcrt) and status (dis-
abled, down) of the connection is displayed.
mrinfo must be run as root.
