Interface Command; General Configuration Tasks - Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X Configuration Manual

interface Command

The interface command has the following format:
interface interfaceType interfaceSpecifier
Each interface type has an interface specifier associated with it. The interface specifier
identifies the physical location of the interface on the router, such as the chassis slot
and port number, and logical interface information, such as a T1 channel on a
channelized T3 interface.
For detailed information about interface types and specifiers and for specific syntax
for the interface command, see the Interface Types and Specifiers in JUNOSe
Command Reference Guide.

Determine IP-addressing information and information about the physical and
logical characteristics of the various interfaces that you want to configure.
Determine information about the link-layer protocols.
Determine how to organize virtual routers on the router.
Determine how IPSec will be used to provide security.
Determine routing information that defines all or part of the network.
Create the virtual routers.
Configure the interfaces and subinterfaces (such as channelized T3, OCx/STMx,
and HDLC data channels) over which the higher-layer protocols run.
Configure the data link-layer protocols, such as Frame Relay, PPP, and ATM, that
run over these physical interfaces.
Configure the general IP information from which the other routing protocols will
operate.
Configure IP tunnels, shared interfaces, and subscriber interfaces.
Configure IPSec.
Configure the routing protocols that will run on the router, such as IP multicasting
protocols, OSPF, IS-IS, RIP, BGP-4, and MPLS.
Configure the Virtual Router Redundancy Protocol (VRRP) on IP/Ethernet
interfaces.
Configure QoS and policy management.
Configure the router for remote access.
Use the appropriate show commands to display network activity on each of the
interfaces that you have configured. Do this to verify that they are operating as
you expect and to help improve the management of your network.
