Domain Routing
Domain routing is used in multi-router local network configurations. Normally,
to accesss a device connected to one router from another router on the network,
its
to accesss a device connected to one router from another router on the network,
its
IP
address must be used. Activating domain routing (by clicking in the appro-
priate check box) allows the user to access to the computer by name (as well as
IP
address).
IP Address Distribution
The Router’s
DHCP
server makes it possible to easily add computers configured as
DHCP
clients to the network. It provides a mechanism for allocating
IP
addresses to
these hosts and for delivering network configuration parameters to them.
For example, a client (host) sends out a broadcast message on the network request-
ing an
ing an
IP
address for itself. The
DHCP
server then checks its list of available address-
es and leases a local
IP
address to the host for a specific period of time and simul-
taneously designates this
IP
address as “taken.” At this point, the host is configured
with an
IP
address for the duration of the lease.
The host can choose to renew an expiring lease or let it expire. If it chooses to
renew a lease, it will also receive current information about network services, as
it did with the original lease, allowing it to update its network configurations to
reflect any changes that occurred since it first connected to the network. If the host
wishes to terminate a lease before its expiration, it can send a release message to the
renew a lease, it will also receive current information about network services, as
it did with the original lease, allowing it to update its network configurations to
reflect any changes that occurred since it first connected to the network. If the host
wishes to terminate a lease before its expiration, it can send a release message to the
DHCP
server, which will then make the
IP
address available for use by others.
The Router’s
DHCP
server:
• Displays a list of all
DHCP
hosts devices connected to the Router.
• Defines the range of
IP
addresses that can be allocated in the network.
• Defines the length of time for which dynamic
IP
addresses are allocated.
• Provides the above configurations for each network device and can be con-
figured and enabled/disabled separately for each network device.
• Can assign a static lease to a network computer so that it receives the same
IP
address each time it connects to the network, even if this
IP
address is within
the range of addresses that the
DHCP
server may assign to other computers.
• Provides the
DNS
server with the host name and
IP
address of each com-
puter connected to the network.
