.SH DESCRIPTION
|
|
|
|
|
.I map-mbone
|
1995-03-31 21:18:13 +00:00
|
|
|
attempts to display all multicast routers that are reachable from the multicast
|
1995-06-13 18:05:16 +00:00
|
|
|
.I starting_router.
|
|
|
|
|
If not specified on the command line, the default multicast
|
|
|
|
|
.I starting_router
|
|
|
|
|
is the localhost.
|
|
|
|
|
.PP
|
|
|
|
|
.I map-mbone
|
|
|
|
|
traverses neighboring multicast routers by sending the ASK_NEIGHBORS IGMP
|
|
|
|
|
message to the multicast starting_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 recent multicast version
|
|
|
|
|
number, then
|
|
|
|
|
.I map-mbone
|
1995-03-31 21:18:13 +00:00
|
|
|
requests additional information such as metrics, thresholds, and flags from the
|
|
|
|
|
multicast router. For each new occurrence of neighboring multicast router in
|
|
|
|
|
the reply and provided the flooding option has been selected, then
|
1995-06-13 18:05:16 +00:00
|
|
|
.I map-mbone
|
1995-03-31 21:18:13 +00:00
|
|
|
asks each of this multicast router for a list of neighbors. This search
|
|
|
|
|
for unique routers will continue until no new neighboring multicast routers
|
|
|
|
|
are reported.

.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
|
1995-03-31 21:18:13 +00:00
|
|
|
.I map-mbone
|
|
|
|
|
to terminate.
|
|
|
|
|
Non-zero debug levels have the following effects:
|
1995-06-13 18:05:16 +00:00
|
|
|
.IP "level 1"
|
1995-03-31 21:18:13 +00:00
|
|
|
packet warnings are printed to stderr.
|
1995-06-13 18:05:16 +00:00
|
|
|
.IP "level 2"
|
1995-03-31 21:18:13 +00:00
|
|
|
all level 1 messages plus notifications down networks are printed to stderr.
|
1995-06-13 18:05:16 +00:00
|
|
|
.IP "level 3"
|
1995-03-31 21:18:13 +00:00
|
|
|
all level 2 messages plus notifications of all packet
|
|
|
|
|
timeouts are printed to stderr.

.PP
|
|
|
|
|
"\-f" option sets flooding option. Flooding allows the recursive search
|
|
|
|
|
of neighboring multicast routers and is enable by default when starting_router
|
|
|
|
|
is not used.
|
|
|
|
|
.PP
|
|
|
|
|
"\-g" option sets graphing in GraphEd format.
|
|
|
|
|
.PP
|
|
|
|
|
"\-n" option disables the DNS lookup for the multicast routers names.
|
|
|
|
|
.PP
|
|
|
|
|
"\-r retry_count" sets the neighbor query retry limit. Default is 1 retry.
|
|
|
|
|
.PP
|
|
|
|
|
"\-t timeout_count" sets the number of seconds to wait for a neighbor query
|
|
|
|
|
reply before retrying. Default timeout is 2 seconds.
