Gateway Routing Daemon (GATED) Configuration Reference
A.10 Interface Statements
preference preference
Sets the preference for routes to this interface when
it is up and appears to be functioning properly. The
default preference is 0.
down preference preference
Sets the preference for routes to this interface
when GATED does not believe it to be functioning
properly, but the kernel does not indicate it is
down. The default value is 120.
passive Prevents GATED from changing the preference of
the route to this interface if it is not believed to be
functioning properly due to lack of received routing
information. The GATED daemon only performs
this check if the interface is actively participating
in a routing protocol.
simplex Defines an interface as unable to hear its own
broadcast packets. Some systems define an
interface as simplex with the IFF_SIMPLEX flag;
others require it to be specified in the configuration
file. On simplex interfaces, a sender’s own packets
are assumed to have been looped back in software
and are not used as an indication that the interface
is functioning properly.
reject Specifies that the address of the interface matching
these criteria is used as the local address when
installing reject routes in the kernel.
Use
reject only with systems based on BSD
4.3 Tahoe or earlier that have installed a
reject/blackhole pseudo-interface.
blackhole Specifies that the address of the interface matching
these criteria is used as the local address when
installing reject routes in the kernel. Use this
only with systems based on BSD 4.3 Tahoe or
earlier that have installed a reject/blackhole pseudo
interface.
The define portion of the interfaces statement defines interfaces that might not
be present when GATED is started so they may be referenced in the configuration
file when strictinterfaces is defined. The following are valid define keywords:
broadcast address Defines the interface as broadcast capable (for
example, Ethernet or Token Ring) and specifies the
broadcast address.
pointopoint address Defines the interface as a point-to-point interface
(for example, SLIP or PPP) and specifies the
address on the local side. The first address on
the define statement references the address of the
host on the remote end of the interface, the address
specified after this pointopoint keyword defines the
address on the local side of the interface.
netmask mask Specifies the subnet mask to be used on this
interface. This is ignored on point-to-point
interfaces.
multicast Specifies that the interface is multicast capable.
AS autonomoussystem Specifies the AS that will be used to create an AS
path associated with the route created from the
definition of this interface.
