Technical data

router_id
An IP address used as unique identifier assigned to represent a specific router.
This is usually the address of an attached interface.
router solicitation
A Router Discovery Protocol message sent out by a host to request router
advertisement responses from a router.
routing
A Network layer function, implemented in intermediate systems, that determines
the path along which data travels to its destination and the movement of that
data. See also decision.
routing database
The database that contains routing information, including destination host names,
IP addresses for the hosts, gateway host names, and IP addresses for the gateways.
There are two route databases: the static route database that is maintained on
disk, and the volatile database in memory.
The repository of all of GATED’s retained routing information, used to make
decisions and as a source for routing information that is propagated.
routing domain
A set of hosts and routers within a single administrative domain that operates
according to the same routing procedures.
Routing Information Protocol (RIP)
The protocol that enables gateways to broadcast their current routing database to
hosts and networks that are connected directly to them. software implements the
RIP through its dynamic routing Zserver.
One of a class of interior gateway protocols, described in more detail in the RIP
section of
gated.proto
(4).
routing protocol
A protocol sent between routers by which routers exchange information on how to
route to various parts of the network. The TCP/IP family of protocols has many of
this type of protocol, such as RIP, EGP, BGP, OSPF, and dual IS-IS.
routing socket
A data structure used by processes to communicate routing information to the
kernel. A process can add and delete routes, dump the routing table, and read
messages from the kernel. The only type of socket supported in the
AF_ROUTE
domain is a raw socket.
routing table
The repository of all of
gated
’s retained routing information, used to make
decisions and as a source for routing information that is propagated.
RPC
See remote procedure call and ONC RPC.
rshell
Remote shell; a remote utility that enables the user to open a shell session on a
remote host.
RTL
See run-time library.
RTT
See round-trip time.
