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-660HN-F1A will broadcast its routing table periodically and
incorporate the RIP information that it receives.
• In Only - the P-660HN-F1A will not send any RIP packets but will accept all RIP
packets received.
• Out Only - the P-660HN-F1A will send out RIP packets but will not accept any
RIP packets received.
• None - the P-660HN-F1A 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-660HN-F1A 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.
