4.4 LAN TCP/IP

The BIPAC-5100/5100W has built-in DHCP server capability that assigns IP addresses and

DNS servers to systems that support DHCP client capability.

4.4.1 Factory LAN Defaults

The LAN parameters of the BIPAC-5100/5100W are preset in the factory with the following

values:

 IP address of 192.168.1.254 with subnet mask of 255.255.255.0 (24 bits)

 DHCP server enabled with 100 client IP addresses starting from 192.168.1.100.

These parameters should work for the majority of installations. If your ISP gives you explicit

DNS server address(es), read the embedded web configurator help regarding what fields need

to be configured.

4.4.2 IP Address and Subnet Mask

Refer to the IP Address and Subnet Mask section in the Wizard Setup chapter for this

information.

4.4.3 RIP Setup

RIP (Routing Information Protocol) allows a router to exchange routing information with other

routers. The RIP Direction field controls the sending and receiving of RIP packets. When set

to:

1. Both - the BIPAC-5100/5100W will broadcast its routing table periodically and incorporate

the RIP information that it receives.

2. In Only - the BIPAC-5100/5100W will not send any RIP packets but will accept all RIP

packets received.

3. Out Only - the BIPAC-5100/5100W will send out RIP packets but will not accept any RIP

packets received.

4. None - the BIPAC-5100/5100W will not send any RIP packets and will ignore any RIP

packets received.

The Version field controls the format and the broadcasting method of the RIP packets that the

BIPAC-5100/5100W sends (it recognizes both formats when receiving). RIP-1 is universally

supported; but RIP-2 carries more information. RIP-1 is probably adequate for most networks,

unless you have an unusual network topology.

Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that

RIP-2B uses subnet broadcasting while RIP-2M uses multicasting.

4.4.4 Multicast

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1

recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to

a group of hosts on the network - not everybody and not just 1.
