gateway
An intermediate destination by which packets are delivered to their ultimate destination. A host
address of another router that is directly reachable via an attached network. As with any host address
it may be specified symbolically.
gateway_list
A list of one or more gateways separated by white space.
HELLO
One of a class of interior gateway protocols, described in more detail in the HELLO section of the Pro-
tocol Overview.
host
The IP address of any host. Usually specified as a dotted quad, four values in the range of 0 to 255
inclusive separated by dots (.). For example 132.236.199.63 or 10.0.0.51. It may also be
specified as an eight digit hexadecimal string preceded by 0x. For example 0x???????? or
0x0a000043. Finally, if options noresolv is not specified, a symbolic hostname. For example
gated.cornell.edu or nic.ddn.mil. The numeric forms are much preferred over the symbolic
form.
interface
The host address of an attached interface. This is the address of a broadcast, nbma or loopback
interface and the remote address of a point-to-point interface. As with any host address it may be
specified symbolically.
interface
The connection between a router and one of its attached networks. A physical interface may be
specified by a single IP address, domain name, or interface name. (Unless the network is an unnum-
bered 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. Dynamic interfaces can be added or deleted and indicated as up or down as well as
changes to address, netmask and metric parameters.
igp
interior gateway protocol
interior routing protocol
One of a class of routing protocols used to exchange routing information within an autonomous sys-
tem. A detailed explanation of interior gateway protocols is available in the Protocol Overview.
interface_list
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. See the
section on interface lists for more information.
IS-IS
One of a class of interior gateway protocols.
local_address
The host address of an attached interface. This is the address of a broadcast, nbma or loopback
interface and the local address of a point-to-point interface. As with any host address it may be
specified symbolically.
mask
A means of subdividing networks using address modification. A mask is a dotted quad specifying
which bits of the destination are significant. Except when used in a route filter, GateD only supports
contiguous masks.
mask length
The number of significant bits in the mask.
metric
One of the units used to help a system determine the best route. Metrics may be based on hop count,
routing delay, or an arbitrary value set by the administrator depending on the type of routing proto-
col. Routing metrics may influence the value of assigned internal preferences. (See preference.)
This sample table shows the range of possible values for each routing protocol metric and the value
used by each protocol (See Protocol Overview.) to reach a destination.
