multiaccess networks
Those physical networks that support the attachment of multiple (more than two) routers. Each pair
of routers on such a network is assumed to be able to communicate directly.
natural mask
The format of an IP address contains the network address and the host address. The natural mask is
a default value applied to the 3 class addresses:
0xff000000 for class A (network.host.host.host),
0xffff0000 for class B (network.network.host.host) and
0xffffff00 for class C (network.network.network.host).
neighbor
Another router which with implicit or explicit communication is established by a routing protocol.
Neighbors are usually on a shared network, but not always. This term is mostly used in OSPF and
EGP. Usually synonymous with peer.
neighboring routers
Two routers that have interfaces to a common network. On multiaccess networks, routers are dynami-
cally discovered by the OSPF HELLO protocol.
network
Any packet-switched network. A network may be specified by its IP address or network name. The
host bits in a network specification must be zero. Default may be used to specify the default network
(0.0.0.0).
network
The IP address of a network. Usually specified as a dotted quad, one to four values in the range of 0 to
255 inclusive separated by dots (.). For example 132.236.199, 132.236 or 10. It may also be
specified as a hexadecimal string preceded by 0x with an even number of digits between two and
eight. For example 0x??????, 0x???? or 0x0a. Also allowed is the symbolic value default which
has the distinguished value 0.0.0.0, the default network. If options noresolv is not specified, a
symbolic network name can be used, for example nr-tech-prod, cornellu-net and arpanet.
The numeric forms are much preferred over the symbolic form.
number
A positive integer.
OSPF
Open Shortest Path First
One of a class of interior gateway protocols, described in more detail in the OSPF section of the Proto-
col Overview.
ospf_area
peer
Another router which with implicit or explicit communication is established by a routing protocol.
Peers are usually on a shared network, but not always. This term is mostly used by BGP. Usually
synonymous with neighbor.
port
A UDP or TCP port number. Valid values are from 1 through 65535 inclusive.
preference
A preference is a value between 0 (zero) and 255 used to select between many routes to the same
destination. The route with the best (numerically lowest) preference is as the active route. The active
route is the one installed in the kernel forwarding table and exported to other protocols. Preference
zero is usually reserved for routes to directly attached interfaces. A default preference is assigned to
each source from which GateD receives routes. (See Preference.)
