! 73: .Os
! 74: .Sh NAME
! 75: .Nm mrinfo
! 76: .Nd displays configuration info from a multicast router
! 77: .Sh SYNOPSIS
! 78: .Nm mrinfo
! 79: .Op Fl hn
! 80: .Op Fl d Ar level
! 81: .Op Fl r Ar count
! 82: .Op Fl t Ar seconds
! 83: .Ar router
! 84: .Sh DESCRIPTION
! 85: .Nm
! 86: attempts to display the configuration information from the specified multicast capable
! 87: .Ar router .
! 88: .Pp
! 89: .Nm
! 90: uses the ASK_NEIGHBORS IGMP message to query the specified multicast
! 91: router.
! 92: If the router responds, the version number and a list of their
! 93: neighboring multicast router addresses is part of the response.
! 94: If the responding router has a recent multicast version number, then
! 95: .Nm
! 96: requests additional information such as metrics, thresholds,
! 97: and flags from the multicast router.
! 98: Once the specified multicast router responds,
! 99: the configuration is displayed to the standard output.
! 100: .Pp
! 101: The options are as follows:
! 102: .Bl -tag -width timeout_levelxyz
! 103: .It Fl h
! 104: Print a help message and exit.
! 105: .It Fl n
! 106: Use numerical address instead of a symbolic host name.
! 107: .It Fl d Ar level
! 108: sets the debug level.
! 109: When the debug level is greater than the default value of 0,
! 110: additional debugging messages are printed.
! 111: Regardless of the debug level,
! 112: an error condition will always write an error message and cause
! 113: .Nm
! 114: to terminate.
! 115: Non-zero debug levels have the following effects (printed to stderr):
! 116: .Pp
! 117: .Bl -tag -width 1n -compact -offset indent
! 118: .It 1
! 119: packet warnings.
! 120: .It 2
! 121: all level 1 messages plus notifications of down networks.
! 122: .It 3
! 123: all level 2 messages plus notifications of all packet timeouts.
! 124: .El
! 125: .It Fl r Ar count
! 126: sets the neighbor query retry count limit.
! 127: The default is to do 3 retries.
! 128: .It Fl t Ar seconds
! 129: sets the timeout in number of seconds to wait for a neighbor query reply.
! 130: The default timeout is 4 seconds.
! 131: .El
! 132: .Sh EXAMPLES
! 133: .Bd -literal
! 134: # mrinfo mbone.phony.dom.net
! 135: 127.148.176.10 (mbone.phony.dom.net) [version 3.3]:
! 136: 127.148.176.10 -> 0.0.0.0 (?) [1/1/querier]
! 137: 127.148.176.10 -> 127.0.8.4 (mbone2.phony.dom.net) [1/45/tunnel]
! 138: 127.148.176.10 -> 105.1.41.9 (momoney.com) [1/32/tunnel/down]
! 139: 127.148.176.10 -> 143.192.152.119 (mbone.dipu.edu) [1/32/tunnel]
! 140: .Ed
! 141: .Pp
! 142: For each neighbor of the queried multicast router, the IP of the queried router
! 143: is displayed, followed by the IP and name of the neighbor.
! 144: In square brackets the metric (cost of connection)
! 145: and threshold (multicast ttl) is displayed.
! 146: If the queried multicast router has a newer version number, the type (tunnel,
! 147: srcrt) and status (disabled, down) of the connection is displayed.
