37 .Nd router solicitation daemon
49 is the daemon program to send ICMPv6 Router Solicitation messages
50 on the specified interfaces.
51 If a node (re)attaches to a link,
53 sends some Router Solicitations on the link destined to the link-local scope
54 all-routers multicast address to discover new routers
55 and to get non link-local addresses.
59 sends at most 3 Router Solicitations on an interface
60 after one of the following events:
63 Just after invocation of
67 The interface is up after a temporary interface failure.
69 detects it by periodically probing if the status of the
70 interface is active or not.
71 Note that some network cards and drivers do not allow users
72 to extract link state.
75 cannot detect the change of the interface status.
79 option is specified and
81 daemon cannot get the interface status.
82 This feature does not conform to IPv6 neighbor discovery
83 specification, but is provided for mobile stations.
84 Default interval of router advertisements, which is on the order of 10
85 minutes, is slightly long for mobile stations.
86 This feature is provided
87 for such stations so that they can find new routers as soon as possible
88 when they attach another link.
93 sends a Router Solicitation, and receives a valid Router Advertisement,
94 it desists from sending additional solicitations on that interface, until
95 the next time one of the above events occurs.
97 When sending a Router Solicitation on an interface,
99 includes a Source Link-layer address option if the interface
100 has its link-layer address.

125 If this option is specified,
127 sends probing packets to default routers that have advertised Router

130 Moreover, if the option is specified,
132 periodically sends Router Solicitation on an interface that does not support
