NAME
map-mbone - Multicast Router Connection Mapper
SYNOPSIS
/usr/sbin/map-mbone
[-d debuglevel][
-f][-g][-n][-r retries][-t
timeout][multicast-
router ]
DESCRIPTION
map-mbone requests the multicast router connection information from the multicast-router, and prints
the information to the standard out.
map-mbone sends out the ASK_NEIGHBORS igmp message to the
multicast-router. When the multicast-router receives the request, it sends back its configuration informa-
tion. multicast-router can be either an ip address or a system name.
If the multicast-router is not specified, flood mode is on by default and the igmp request message is sent to
all the multicast router on the local network. With flood mode on, when
map-mbone finds new neighbor
routers from the replies, it will send the same igmp request to the new neighbor routers. This activity con-
tinues until no new neighbor routers are reported in the replies.
The command line options are:
-ddebuglevel Sets the level for printing out the debug message. The default is 0, which prints only
error and warning messages. Debug level three prints most the messages.
-rretries Sets the retry times to poll the routing daemon for information. The default is 1.
-ttimeout It specifies the timeout value in seconds for waiting the reply. The default value is 2
seconds.
-f Sets the flood mode on. It is the default value when no multicast-router is given on the
command line input.
-g Generates output in GRaphEd format.
-n Disable DNS lookup for the multicast router names.
The output contains the interface configuration information of the requested router(s). The format for
each interface output is:
interface_addr -> neighbor_addr (neighbor_name) [metrics/thresh/flags]
If there are multiple neighbor routers on one interface, they will all be reported. The neighbor_name will
not be printed if the
-n option is specified on the command line.
The possible values for flags are:
tunnel Neighbors are reached via tunnel.
srcrt The tunnel uses IP source routing.
down The interface is down.
disabled The interface is administratively disabled for multicast routing.
querier The local router is the querier of the subnet.
The format of the GRaphEd output is:
interface_addr_in_integer {$ NP low_byte_addr high_byte_addr} node_name
[ neighbor_addr_in_integer metrics/threshold/flags ]
If there is no neighbor router on an interface, then a * will be put next to the node_name. If there are mul-
tiple neighbor routers on one interface, all of them will be reported. The possible values for flags are:
E The neighbor is reached via tunnel.
P The neighbor is on the same network/subnet.
D The interface is down.
Please see mrouted(1M) for metrics and thresh.
Note
map-mbone must be run as root.
