An interface is the connection between a router and one of its attached networks. A physical interface may

be speciﬁed by interface name, by IP address, or by domain name, (unless the network is an unnumbered

point-to-point network.) Multiple levels of reference in the conﬁguration language allow identiﬁcation of

interfaces using wildcard, interface type name, or delete word address. Be careful with the use of interface

names as future Unix operating systems may allow more than one address per interface. The interface_list

is a list of one or more interface names including wildcard names (names without a number) and names

which may specify more than one interface or address, or the token all for all interfaces.

options

Allows conﬁguration of some global options related to interfaces. These are:

strictinterfaces

Indicates that it is a fatal error to reference an interface in the conﬁguration ﬁle that is not

present when GateD is started and not listed in a define statement. Without this option a

warning message will be issued but GateD will continue.

scaninterval time

Speciﬁes how often GateD scans the kernel interface list for changes. The default is every

15 seconds on most systems, and 60 seconds on systems that pass interface status changes

through the routing socket (BSD 4.4). Note that GateD will also scan the interface list on

receipt of a SIGUSR2.

aliases-nh ( primary | lowestip | keepall )

Speciﬁes which address GateD will install as the next hop for interface routes when multi-

ple addresses are assigned to an interface like the Service Guard environment. If primary

is used, the primary interface address (default) will be installed. If lowestip is used, the

address with the lowest IP address will be installed. If keepall is used, all interface routes

are kept in the kernel up to a maximum of RT_N_MULTIPATH routes. This is a compile-

time constant. This is a global parameter that may be overridden for interfaces using the

interface option.

interface interface_list

Sets interface options on the speciﬁed interfaces. An interface list is all or a list of interface

names (see warning about interface names), domain names, or numeric addresses. Options avail-

able on this statement are:

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.
