Configuring Virtual Routers

Copyright © 2010, Juniper Networks, Inc.
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.
The configuration process for E Series routers involves the following general tasks:
Determine IP-addressing information and information about the physical and logical
1.
characteristics of the various interfaces that you want to configure.
Determine information about the link-layer protocols.
2.
Determine how to organize virtual routers on the router.
3.
Determine how IPSec will be used to provide security.
4.
Determine routing information that defines all or part of the network.
5.
Create the virtual routers.
6.
Configure the interfaces and subinterfaces (such as channelized T3, OCx/STMx, and
7.
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
8.
over these physical interfaces.
Configure the general IP information from which the other routing protocols will
9.
operate.
Configure IP tunnels, shared interfaces, and subscriber interfaces.
10.
Configure IPSec.
11.
Configure the routing protocols that will run on the router, such as IP multicasting
12.
protocols, OSPF, IS-IS, RIP, BGP-4, and MPLS.
Configure the Virtual Router Redundancy Protocol (VRRP) on IP/Ethernet interfaces.
13.
Configure QoS and policy management.
14.
Configure the router for remote access.
15.
Use the appropriate show commands to display network activity on each of the
16.
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.
Multiple distinct virtual routers are supported within a single router, which allows service
providers to configure multiple, separate, secure routers within a single chassis. These
routers are identified as virtual routers (VRs). Applications for this function include the
