Dynamic Route RIP (Routing Information Protocol) allows a router to exchange routing
information with other routers.
Select the RIP version from RIP1, RIP2-B and RIP2-M.
Direction Use this field to control how much routing information the P-660RU-Tx
sends and receives on the subnet.
Select the RIP direction from None, Both, IN Only and OUT Only.
Multicast Multicast packets are sent to a group of computers on the LAN and are
an alternative to unicast packets (packets sent to one computer) and
broadcast packets (packets sent to every computer).
IGMP is a network-layer protocol used to establish membership in a
multicast group. The P-660RU-Tx supports IGMP v1, IGMP v2 and
IGMP v3. Select Disabled to turn off the feature.
DHCP
DHCP If set to Enabled, your P-660RU-Tx can assign IP addresses, an IP
default gateway and DNS servers to operating systems that support
the DHCP client.
If set to Disabled, the DHCP server will be disabled.
If set to Relay, the P-660RU-Tx acts as a surrogate DHCP server and
relays DHCP requests and responses between the remote server and
the clients.

Summary
Click this to display a summary table for the IP address pool. See
Section 8.2.1 on page 79 for more details.
The P-660RU-Tx is pre-configured with a pool of IP addresses for the
DHCP clients (DHCP Pool). See the product specifications in the
appendices. Do not assign static IP addresses from the DHCP pool to
your LAN computers.
IP Pool Count This field specifies the size, or count of the IP address pool.
Lease Time This is the period of time DHCP-assigned addresses is used.
DHCP automatically assigns IP addresses to clients when they log in.
DHCP centralizes IP address management on central computers that
run the DHCP server program. DHCP leases addresses, for a period of
time, which means that past addresses are “recycled” and made
available for future reassignment to other systems.
DNS
DNS Relay Select Auto Discovered DNS Server Only if your ISP dynamically
assigns DNS server information (and the P-660RU-Tx's WAN IP
address).
Select User Discovered DNS Server Only if you have the IP address
of a DNS server. You have to specify the primary and secondary DNS
servers in the following fields.
