+.Sh NAME
+.Nm XNSrouted
+.Nd NS Routing Information Protocol daemon
+.Sh SYNOPSIS
+.Nm XNSrouted
+.Op Fl q
+.Op Fl s
+.Op Fl t
+.Op Ar logfile
+.Sh DESCRIPTION
+.Nm XNSrouted
+is invoked at boot time to manage the Xerox NS routing tables.
+The NS routing daemon uses the Xerox NS Routing
+Information Protocol in maintaining up to date kernel routing
+table entries.
+.Pp
+Available options:
+.Bl -tag -width logfile
+.It Fl q
+Do not supply routing information (opposite of
+.Fl s
+option below).
+.It Fl s
+Forces
+.Nm XNSrouted
+to supply routing information whether it is acting as an internetwork
+router or not.
+.It Fl t
+All packets sent or received are
+printed on the standard output. In addition,
+.Nm XNSrouted
+will not divorce itself from the controlling terminal
+so that interrupts from the keyboard will kill the process.
+.It Ar logfile
+Name of file in which
+.Nm XNSrouted Ns 's
+actions should be logged. This log contains information
+about any changes to the routing tables and a history of
+recent messages sent and received which are related to
+the changed route.
+.El
+.Pp
+In normal operation
+.Nm XNSrouted
+listens
+for routing information packets. If the host is connected to
+multiple NS networks, it periodically supplies copies
+of its routing tables to any directly connected hosts
+and networks.
+.Pp
+When
+.Nm XNSrouted
+is started, it uses the
+.Dv SIOCGIFCONF
+.Xr ioctl 2
+to find those
+directly connected interfaces configured into the
+system and marked
+.Dq up
+(the software loopback interface
+is ignored). If multiple interfaces
+are present, it is assumed the host will forward packets
+between networks.
+.Nm XNSrouted
+then transmits a
+.Em request
+packet on each interface (using a broadcast packet if
+the interface supports it) and enters a loop, listening
+for
+.Em request
+and
+.Em response
+packets from other hosts.
+.Pp
+When a
+.Em request
+packet is received,
+.Nm XNSrouted
+formulates a reply based on the information maintained in its
+internal tables. The
+.Em response
+packet generated contains a list of known routes, each marked
+with a
+.Dq hop count
+metric (a count of 16, or greater, is
+considered
+.Dq infinite ) .
+The metric associated with each
+route returned provides a metric
+.Em relative to the sender .
+.Pp
+.Em Response
+packets received by
+.Nm XNSrouted
+are used to update the routing tables if one of the following
+conditions is satisfied:
+.Bl -bullet
+.It
+No routing table entry exists for the destination network
+or host, and the metric indicates the destination is ``reachable''
+(i.e. the hop count is not infinite).
+.It
+The source host of the packet is the same as the router in the
+existing routing table entry. That is, updated information is
+being received from the very internetwork router through which
+packets for the destination are being routed.
+.It
+The existing entry in the routing table has not been updated for
+some time (defined to be 90 seconds) and the route is at least
+as cost effective as the current route.
+.It
+The new route describes a shorter route to the destination than
+the one currently stored in the routing tables; the metric of
+the new route is compared against the one stored in the table
+to decide this.
+.El
+.Pp
+When an update is applied,
+.Nm XNSrouted
+records the change in its internal tables and generates a
+.Em response
+packet to all directly connected hosts and networks.
+.Xr Routed 8
+waits a short period
+of time (no more than 30 seconds) before modifying the kernel's
+routing tables to allow possible unstable situations to settle.
+.Pp
+In addition to processing incoming packets,
+.Nm XNSrouted
+also periodically checks the routing table entries.
+If an entry has not been updated for 3 minutes, the entry's metric
+is set to infinity and marked for deletion. Deletions are delayed
+an additional 60 seconds to insure the invalidation is propagated
+to other routers.
+.Pp
+Hosts acting as internetwork routers gratuitously supply their
+routing tables every 30 seconds to all directly connected hosts
+and networks.
