-.Dt ROUTE 8
-.Os BSD 4.4
-.Sh NAME
-.Nm route
-.Nd manually manipulate the routing tables
-.Sh SYNOPSIS
-.Nm route
-.Op Fl dnqtv
-.Ar command
-.Oo
-.Op Ar modifiers
-.Ar args
-.Oc
-.Sh DESCRIPTION
-.Nm Route
-is a utility used to manually manipulate the network
-routing tables. It normally is not needed, as a
-system routing table management daemon such as
-.Xr routed 8 ,
-should tend to this task.
-.Pp
-The
-.Nm
-utility supports a limited number of general options,
-but a rich command language, enabling the user to specify
-any arbitrary request that could be delivered via the
-programmatic interface discussed in
-.Xr route 4 .
-.Pp
-The following options are available:
-.Bl -tag -width indent
-.It Fl n
-Bypass attempts to print host and network names symbolically
-when reporting actions. (The process of translating between symbolic
-names and numerical equivalents can be quite time consuming, and
-may require correct operation of the network; thus it may be expedient
-to forgot this, especially when attempting to repair networking operations).
-.It Fl v
-(verbose) Print additional details.
-.It Fl q
-Suppress all output.
-.El
-.Pp
-The
-.Nm
-utility provides six commands:
-.Pp
-.Bl -tag -width Fl -compact
-.It Cm add
-Add a route.
-.It Cm flush
-Remove all routes.
-.It Cm delete
-Delete a specific route.
-.It Cm change
-Change aspects of a route (such as its gateway).
-.It Cm get
-Lookup and display the route for a destination.
-.It Cm monitor
-Continuously report any changes to the routing information base,
-routing lookup misses, or suspected network partitionings.
-.El
-.Pp
-The monitor command has the syntax:
-.Pp
-.Bd -filled -offset indent -compact
-.Nm route Op Fl n
-.Cm monitor
-.Ed
-.Pp
-The flush command has the syntax:
-.Pp
-.Bd -filled -offset indent -compact
-.Nm route Op Fl n
-.Cm flush
-.Op Ar family
-.Ed
-.Pp
-If the
-.Cm flush
-command is specified,
-.Nm
-will ``flush'' the routing tables of all gateway entries.
-When the address family may is specified by any of the
-.Fl osi ,
-.Fl xns ,
-.Fl atalk ,
-.Fl inet6 ,
-or
-.Fl inet
-modifiers, only routes having destinations with addresses in the
-delineated family will be deleted.
-.Pp
-The other commands have the following syntax:
-.Pp
-.Bd -filled -offset indent -compact
-.Nm route Op Fl n
-.Ar command
-.Op Fl net No \&| Fl host
-.Ar destination gateway
-.Ed
-.Pp
-where
-.Ar destination
-is the destination host or network,
-.Ar gateway
-is the next-hop intermediary via which packets should be routed.
-Routes to a particular host may be distinguished from those to
-a network by interpreting the Internet address specified as the
-.Ar destination argument .
-The optional modifiers
-.Fl net
-and
-.Fl host
-force the destination to be interpreted as a network or a host, respectively.
-Otherwise, if the
-.Ar destination
-has a
-.Dq local address part
-of
-INADDR_ANY
-.Pq Li 0.0.0.0 ,
-or if the
-.Ar destination
-is the symbolic name of a network, then the route is
-assumed to be to a network; otherwise, it is presumed to be a
-route to a host.
-.Pp
-For example,
-.Li 128.32
-is interpreted as
-.Fl host Li 128.0.0.32 ;
-.Li 128.32.130
-is interpreted as
-.Fl host Li 128.32.0.130 ;
-.Fl net Li 128.32
-is interpreted as
-.Li 128.32.0.0;
-and
-.Fl net Li 128.32.130
-is interpreted as
-.Li 128.32.130.0 .
-.Pp
-A
-.Ar destination
-of
-.Ar default
-is a synonym for
-.Fl net Li 0.0.0.0 ,
-which is the default route.
-.Pp
-If the destination is directly reachable
-via an interface requiring
-no intermediary system to act as a gateway, the
-.Fl interface
-modifier should be specified;
-the gateway given is the address of this host on the common network,
-indicating the interface to be used for transmission.
-Alternately, if the interface is point to point the name of the interface
-itself may be given, in which case the route remains valid even
-if the local or remote addresses change.
-.Pp
-The optional modifiers
-.Fl xns ,
-.Fl osi ,
-.Fl atalk ,
-and
-.Fl link
-specify that all subsequent addresses are in the
-.Tn XNS ,
-.Tn OSI ,
-or
-.Tn AppleTalk
-address families,
-or are specified as link-level addresses,
-and the names must be numeric specifications rather than
-symbolic names.
-.Pp
-The optional
-.Fl netmask
-modifier is intended
-to achieve the effect of an
-.Tn OSI
-.Tn ESIS
-redirect with the netmask option,
-or to manually add subnet routes with
-netmasks different from that of the implied network interface
-(as would otherwise be communicated using the OSPF or ISIS routing protocols).
-One specifies an additional ensuing address parameter
-(to be interpreted as a network mask).
-The implicit network mask generated in the AF_INET case
-can be overridden by making sure this option follows the destination parameter.
-.Pp
-For
-.Dv AF_INET6 ,
-the
-.Fl prefixlen
-qualifier
-is available instead of the
-.Fl mask
-qualifier because non-continuous masks are not allowed in IPv6.
-For example,
-.Fl prefixlen Li 32
-specifies network mask of
-.Li ffff:ffff:0000:0000:0000:0000:0000:0000
-to be used.
-The default value of prefixlen is 64 to get along with
-the aggregatable address.
-But 0 is assumed if
-.Cm default
-is specified.
-Note that the qualifier works only for
-.Dv AF_INET6
-address family.
-.Pp
-Routes have associated flags which influence operation of the protocols
-when sending to destinations matched by the routes.
-These flags may be set (or sometimes cleared)
-by indicating the following corresponding modifiers:
-.Bd -literal
--cloning RTF_CLONING - generates a new route on use
--xresolve RTF_XRESOLVE - emit mesg on use (for external lookup)
--iface ~RTF_GATEWAY - destination is directly reachable
--static RTF_STATIC - manually added route
--nostatic ~RTF_STATIC - pretend route added by kernel or daemon
--reject RTF_REJECT - emit an ICMP unreachable when matched
--blackhole RTF_BLACKHOLE - silently discard pkts (during updates)
--proto1 RTF_PROTO1 - set protocol specific routing flag #1
--proto2 RTF_PROTO2 - set protocol specific routing flag #2
--llinfo RTF_LLINFO - validly translates proto addr to link addr
-.Ed
-.Pp
-The optional modifiers
-.Fl rtt ,
-.Fl rttvar ,
-.Fl sendpipe ,
-.Fl recvpipe ,
-.Fl mtu ,
-.Fl hopcount ,
-.Fl expire ,
-and
-.Fl ssthresh
-provide initial values to quantities maintained in the routing entry
-by transport level protocols, such as TCP or TP4.
-These may be individually locked by preceding each such modifier to
-be locked by
-the
-.Fl lock
-meta-modifier, or one can
-specify that all ensuing metrics may be locked by the
-.Fl lockrest
-meta-modifier.
-.Pp
-In a
-.Cm change
-or
-.Cm add
-command where the destination and gateway are not sufficient to specify
-the route (as in the
-.Tn ISO
-case where several interfaces may have the
-same address), the
-.Fl ifp
-or
-.Fl ifa
-modifiers may be used to determine the interface or interface address.
-.Pp
-All symbolic names specified for a
-.Ar destination
-or
-.Ar gateway
-are looked up first as a host name using
-.Xr gethostbyname 3 .
-If this lookup fails,
-.Xr getnetbyname 3
-is then used to interpret the name as that of a network.
-.Pp
-.Nm Route
-uses a routing socket and the new message types
-RTM_ADD,
-RTM_DELETE,
-RTM_GET,
-and
-RTM_CHANGE.
-As such, only the super-user may modify
-the routing tables.
-.Sh DIAGNOSTICS
-.Bl -tag -width Ds
-.It Sy "add [host \&| network ] %s: gateway %s flags %x"
-The specified route is being added to the tables. The
-values printed are from the routing table entry supplied
-in the
-.Xr ioctl 2
-call.
-If the gateway address used was not the primary address of the gateway
-(the first one returned by
-.Xr gethostbyname 3 ) ,
-the gateway address is printed numerically as well as symbolically.
-.It Sy "delete [ host \&| network ] %s: gateway %s flags %x"
-As above, but when deleting an entry.
-.It Sy "%s %s done"
-When the
-.Cm flush
-command is specified, each routing table entry deleted
-is indicated with a message of this form.
-.It Sy "Network is unreachable"
-An attempt to add a route failed because the gateway listed was not
-on a directly-connected network.
-The next-hop gateway must be given.
-.It Sy "not in table"
-A delete operation was attempted for an entry which
-wasn't present in the tables.
-.It Sy "routing table overflow"
-An add operation was attempted, but the system was
-low on resources and was unable to allocate memory
-to create the new entry.
