F-13166-A2-GB20-20 March 1999IP Network Addressing ScenariosFOverviewThis appendix describes a means of configuring 31xx Series devices in anInternet Protocol (IP) network to provide SNMP or Telnet connectivity. Since thereare many possible network addressing schemes, this appendix describes anaddressing scheme for typical customer network management system (NMS)scenarios. This appendix is not intended to be an IP addressing or routingtutorial, and a basic understanding of IP and 31xx Series devices is assumed.The following notes apply to these scenarios: 31xx devices besides the Model 3166 include:— Model 3160 (2-port standalone)— Model 3161 (carrier-mounted card used with auxiliary backplane)— Model 3162 (2-port standalone)— Model 3164 (4-port standalone)— Model 3165 (1-port standalone) Connections to remote devices may be via EDL (for the Model 3166 and2-port and 4-port DSU/CSUs) or FDL; however, the FDL is only available onfull T1 links (not fractional T1s). Check with the service provider to be surethat the FDL is end-to-end (i.e., not terminated at an intermediate point withinthe network). Interconnected 31xx Series devices automatically pass routing informationbetween them; however, a static route to the subnet(s) must be set in therouting table of the NMS host. This route uses the 31xx Series deviceconnected to the LAN (via the LAN Adapter), or the NMS (via a direct PPP orSLIP connection) as a gateway to the subnet(s). In all instances, theaddressing scheme presented works for both the LAN and the directconnections. Although routing table entries are maintained automatically by 31xx Seriesdevices, without the need for user configuration, only a maximum of 100routes is supported for a given device.
