Chapter 7 LAN Setup • 192.168.0.0 - 192.168.255.255 You can obtain your IP address from the IANA, from an ISP or it can be assigned from a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization, you should consult your network administrator for the appropriate IP addresses. Note: Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines above. For more information on address assignment, please refer to RFC 1597, "Address Allocation for Private Internets" and RFC 1466, "Guidelines for Management of IP Address Space". 7.6.5 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: • Both - the P-792H v2 will broadcast its routing table periodically and incorporate the RIP information that it receives. • In Only - the P-792H v2 will not send any RIP packets but will accept all RIP packets received. • Out Only - the P-792H v2 will send out RIP packets but will not accept any RIP packets received. • None - the P-792H v2 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 P-792H v2 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. 7.6.6 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. 98 P-792H v2 User's Guide
