Using Enterprise Edge Services 23

P0910464 Issue 01 Enterprise Edge Networking Operations Guide

IP is a connectionless protocol, which means that there is no established connection

between the end points that communicate. Each packet that travels through the

Internet is treated as an independent unit of data without any relation to another unit

of data. The packets get put in the right order because TCP, the connection-oriented

protocol, keeps track of the packet sequence in a message. In the Open Systems

Interconnection (OSI) communication model, IP is in layer 3, the Networking

Layer.

Enterprise Edge IP routing specifics

Using Enterprise Edge Unified Manager, you can perform the following routing

configuration options:

• Add or delete the interfaces to routing protocols

• Configure routing protocol options

• Add and delete static routes

• Add or delete filters

• Set filter actions

For instructions on configuring routing options, see Routing on page 85.

The followings table shows the Enterprise Edge IP routing protocols and the

precedence order when conflict or redundant routes occur.

IP Addressing Overview

IP addresses follow the format nnn.nnn.nnn.nnn, where nn is a number between 0

and 255. For example, 192.123.4.56 or 10.1.1.1. IP addresses enable computers to

communicate to each other. Both servers and workstations on a network must have

IP addresses. There are two types of IP addresses:

Dynamic – A dynamic IP address changes. Dynamic IP addresses are assigned

to computers by an IP address server as the computer needs it. Usually there is

a particular range or scope of IP addresses that your network uses. With

dynamic IP addressing, a computer can have a different IP address every time

it connects to the network. Other devices need to know the computer’s IP

address so that they can communicate with it. The IP address server manages

the assignment of IP addresses to the client workstations.

Static – A static or fixed IP address never changes. It is assigned to a computer

permanently. The computer has the same IP address every time it connects to

the network and is known to other devices on the network by that IP address.
