Chapter 4 Ip Networking; Ip Networking Overview - Cisco ONS 15327 User Documentation

IP Networking
This chapter explains how to set up Cisco ONS 15327s in internet protocol (IP) networks and includes:
•
•
•
The chapter does not provide a comprehensive explanation of IP networking concepts and procedures.
To set up ONS 15327s within an IP network, you must work with a LAN administrator or other
Note
individual at your site who has IP networking training and experience. To learn more about IP
networking, many outside resources are available. IP Routing Fundamentals, by Mark Sportack
(Cisco Press, 1999), provides a comprehensive introduction to routing concepts and protocols in IP
networks.

4.1 IP Networking Overview

ONS 15327s can be connected in many different ways within an IP environment:

Scenarios showing Cisco ONS 15327s in common IP network configurations
Procedures for creating static routes
Procedures for using the Open Shortest Path First (OSPF) protocol
They can be connected to LANs through direct connections or a router.
IP Subnetting can create ONS 15327 node groups, which allow you to provision non-DCC
connected nodes in a network.
Different IP functions and protocols can be used to achieve specific network goals. For example,
Proxy Address Resolution Protocol (ARP) enables one LAN-connected ONS 15327 to serve as a
gateway for ONS 15327s that are not connected to the LAN.
You can create static routes to enable connections among multiple CTC sessions with ONS 15327s
that reside on the same subnet but have different destination IP addresses.
If ONS 15327s are connected to OSPF networks, ONS 15327 network information is automatically
communicated across multiple LANs and WANs.
The ONS 15327 proxy server can be used to control the visibility and accessibility between CTC
computers and ONS 15327 element nodes.
