Routing Overview

Routing is the process of delivering a message across a network or networks. This process has two primary components: the exchange of routing information to forward packets accurately from source to destination and the packet-forwarding procedure.

Note: Before configuring routing protocols, you must first configure security filters. For more information, see the JUNOS Software Security Configuration Guide.

To use the routing capabilities of a Juniper Networks device, you must understand the fundamentals of IP routing and the routing protocols that are primarily responsible for the transmission of unicast traffic. To read this chapter, you need a basic understanding of IP addressing and TCP/IP.

Note: When configuring IPv6 addressing and routing on a J-series Service Router, you must enable IPv6 in secure context. For information about IPv6, see the JUNOS Routing Protocols Configuration Guide.

This chapter includes the following topics. For more information, see the JUNOS Routing Protocols Configuration Guide.
