management system such as Sun Connect's Sun Net Manager and Hewlett-Packard's HP Open View to
monitor and control Loop-IP 6610 series. This enables the user to integrate WAN equipment management
with LAN SNMP network management systems.
Figure 3-1 SNMP Connection
Once the SNMP agent is activated, user can verify whether the Loop-IP 6610 is running successfully by
using ping command to check if Loop-IP 6610 series is responding or not.
eg. $ ping 192.1.100.45
192.1.100.45 is alive
Please refer to each respective SNMP manager operation instruction to incorporate the Loop-IP 6610 series
enterprise MIB to the system.
The user can use a Telnet program which simulates a VDS100 to access the Loop-IP 6610 command
screen. A maximum of four users at a time can use the Telnet connection to the Loop-IP 6610. Because the
IP 6610 uses Ethernet or E1 for its Telnet connection, the user does not have to set the console port’s baud
rate.
3.15 RIP1 and RIP2 Routing Protocols
For the internet and for private networks, IP (Internet Protocol) is the worlds most commonly used language.
In the IP, protocol defines a means by which routing equipment can select the optimum route for
transmitting data packets from one network to another. Two common protocols are RIP1 (Routing
Information Protocol Version 1) and RIP2 (Routing Information Protocol Version 2).
RIP1 was initially developed as an internal gateway protocol which allowed information to be exchanged
within an autonomous system. An autonomous system can be defined as a set of routers under the same
administration. Such a system normally contains anywhere from one to a few hundred routers but no limit
to the number of routers is defined.
RIP1 was developed when most autonomous systems generally had less than one hundred routers. In RIP1
traffic is passed between the source and the destination IP addresses in the packet via the least possible
number of jumps. To determine the best path between subnets, routers exchange information on a regular
basis. Every 30 seconds a router broadcasts RIP1 information on all router interfaces. After receiving RIP1
information from other routers, the router receiving the packets processes the information to determine if a
better path is available.
Without going into great detail, it can be simply said that RIP1, while still a very useful protocol, does have
inefficiencies when used on a large autonomous system. RIP2 was developed to address some of these
inefficiencies.
