IP Network Addressing Scenarios

Overview

This appendix describes a means of configuring 31xx Series devices in an Internet
Protocol (IP) network to provide SNMP or Telnet connectivity. Since there are
many possible network addressing schemes, this appendix describes an
addressing scheme for typical customer network management system (NMS)
scenarios. This appendix is not intended to be an IP addressing or routing tutorial,
and a basic understanding of IP and 31xx Series devices is assumed.
The following notes apply to these scenarios:

Connections to remote devices may be via FDL; however, an FDL is only
available on full T1 links (not fractional T1s). Check with the service provider to
be sure that the FDL is end-to-end (i.e., not terminated at an intermediate
point within the network).
Interconnected 31xx Series devices automatically pass routing information
between them; however, a static route to the subnet(s) must be set in the
routing table of the NMS host. This route uses the 31xx Series device
connected to the LAN or the NMS as a gateway to the subnet(s). In all
instances, the addressing scheme presented works for both the LAN and the
direct connections.
Routing table entries are maintained automatically by 31xx Series devices
without the need for user configuration. A maximum of 100 routes is supported
for a given device.
The choice of a host address within a given subnet is completely arbitrary.
Choose any legal host address for a given subnet, without regard to the local
or remote devices.
Although the default route (to the NMS) is configurable for all devices, only
devices that have a direct external connection to an NMS need a default route
set. In the following examples, the default port is set in the device connected to
the LAN.
