conflict markers, but it actually changes nothing. We've been running this code with small changes for some time, this may be useful for checking what those changes. It was unfortunate this module got so far away from the vendor branch (whitespace changes didn't help)

mrinfo \- Displays configuration info from a multicast router

.SH DESCRIPTION
|
|
.I mrinfo
|
|
attempts to display the configuration information from the multicast router
|
|
.I multicast_router.
|
|
.PP
|
|
.I mrinfo
|
|
uses the ASK_NEIGHBORS IGMP message to the specified multicast router. If this
|
|
multicast router responds, the version number and a list of their neighboring
|
|
multicast router addresses is part of that response. If the responding router
|
|
has a recent multicast version number, then
|
|
.I mrinfo
|
|
requests additional information such as metrics, thresholds, and flags from the
|
|
multicast router. Once the specified multicast router responds, the
|
|
configuration is displayed to the standard output.

.SH INVOCATION
|
|
.PP
|
|
"\-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
|
|
.I mrinfo
|
|
to terminate.
|
|
Non-zero debug levels have the following effects:
|
|
.IP "level 1"
|
|
packet warnings are printed to stderr.
|
|
.IP "level 2"
|
|
all level 1 messages plus notifications down networks are printed to stderr.
|
|
.IP "level 3"
|
|
all level 2 messages plus notifications of all packet
|
|
timeouts are printed to stderr.
|
|
.PP
|
|
"\-r retry_count" sets the neighbor query retry limit. Default is 3 retry.
|
|
.PP
|
|
"\-t timeout_count" sets the number of seconds to wait for a neighbor query
|
|
reply. Default timeout is 4 seconds.

|
|
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 displayed. If
|
|
the queried multicast router has a newer version number, the type (tunnel,
|
|
srcrt) and status (disabled, down) of the connection is displayed.
