This document describes Cisco MPLS Tunnel Builder Pro, Version 2.1. Tunnel Builder Pro includes a Backup Route Generator (BRG), which provides Fast ReRoute backup tunnels to protect for single element failures in a network. Tunnel Builder Pro is an enhancement to the Cisco MPLS Tunnel Builder application and incorporates many of its features.
Use these release notes in conjunction with the Cisco MPLS Tunnel Builder Pro Installation and User Guide.
This document contains the following sections:
This section describes the following:
Tunnel Builder Pro can be used on any hardware platform that supports MPLS Traffic Engineering (TE).
The Tunnel Builder Pro application supports devices running Cisco IOS Release 12.0(22)S or later with MPLS TE enabled.
The Tunnel Builder Pro server can run on Solaris, Version 2.8.
The Tunnel Builder Pro client can run on Microsoft Windows 2000 and Microsoft Windows NT.
 |
Note A higher version of the operating system is not necessarily supported. |
The installation of Tunnel Builder Pro requires that you have at least 90 MB of free disk space.
Disk space requirements for the operation of Tunnel Builder Pro depend on the network size.
The following are required on the system where the BRG server is to be installed:
To ensure that BRG performs as expected, the target installation workstation(s) must have the directory $JAVA_HOME/bin in the user's path.
Tunnel Builder Pro 2.1 is a standalone network management application. It is not certified for operation with other network management applications running on the same workstation. In addition, TunnelBuilder Pro 2.1 does not provide direct notification of MPLS configuration changes to other network management applications such as Cisco VPN Solution Center or Cisco element management systems.
Tunnel Builder Pro requires one of the following web browsers and the Java Plug-in specified below:
Windows 2000 and Windows NT—If you are using Netscape Version 4.7, you need to install the Java Plug-in Version 1.3.1 before running Tunnel Builder Pro.
To install Cisco MPLS Tunnel Builder Pro, you must enter two authorized license keys. These license keys are specified on your Right to Use document included in your product. The keys authorize the following:
The application prompts you for these two license keys during setup.
If you exceed the limit of the license, you are notified by a message, like the following:
Number of TE routers (xxx) in the 1.2.3.4 network exceeds the number allowed by your
Tunnel Builder license (yyy). Please contact your administrator.
Where:
You can choose to upgrade the maximum number of TE-enabled routers supported for any single seed router in Tunnel Builder Pro. You will need a new Right to Use document and a new authorized license key for each level through which you upgrade.
Right to Use documents and authorized license keys are available for the following levels:
|
Note If you obtain an evaluation license, you can use the software only for a limited amount of time. |
|

To install and start the Tunnel Builder Pro application on Solaris systems, perform the following steps.
|
Note Default values are in brackets. |
Step 1 Copy the tb-*-kit-sol.tar and tb-*-setup-sol.sh files to a directory under your web server doc directory in which you plan to install the application. For example, /scratch/suitespot/docs/TunnelBuilderPro.
Step 2 Make sure that you can execute the tb-*-setup-sol.sh script:
chmod 755 tb-*-setup-sol.sh
Step 3 Log in as root.
$ su root
password: password
Step 4 Run the ./tb-*setup-sol.sh file.
web-server-doc-dir% ./tb-*-setup-sol.sh
The setup file, tb-*-setup-sol.sh, runs a script that asks you where you want to locate the Tunnel Builder Pro files. Enter the full path of your web server doc directory.
Where (in what directory) would you like the Tunnel Builder Pro client and server to be
installed?
/scratch/suitespot/docs/TunnelBuilderPro
You will have several configuration options.
Please enter the Cisco license key.
Please enter (eval) for evaluation version of BRG, (perm) for permanent version of BRG, or
(none) for Non-BRG version.
If you entered eval or perm, one of the following requests appears:
Please enter the license key for evaluation version.
Please enter the license key for permanent version.
If you entered eval for the BRG license key, the following prompt appears:
Please enter the expiration date for your license in the form dd-mmm-yyyy
What port would you like to use for the Tunnel Builder Pro client and server
communication? [7271]
If you entered eval or perm, the following question appears:
What RMI port would you like to use for the BRG Server? [1098]
Do you want the TunnelBuilder server to use telnet of ssh to access the routers? [telnet]
All routers will be accessed using the method that you selected.
Would you like to receive SNMP trap notification of links and tunnels changing status?
[no]
If you entered yes, the following two questions appear. If you entered no, they do not appear.
What port would you like to use for receiving UDP datagrams? [162]
|
Note If port 162 conflicts with other network management applications, then enter another port number. Port 162 is the standard port for UDP communication. |
What SNMP community string would you like to use? [public]
Would you like to run the Tunnel Builder Pro server in debug mode? [no]
Would you like to enable logging of Tunnel Builder Pro commands and logging of commands
sent to the router? [no]
Step 5 When the installation script is complete, you are asked if you want to run the server automatically.
To start the server manually, execute a startTopoServer command from your web server doc directory.
cd /scratch/suitespot/docs/TunnelBuilderPro/serverkit
web-server-doc-dir% ./startTopoServer
Step 6 To start the Tunnel Builder Pro application, use your web browser to find and select the ServerControl.html file. For example:
http:// server-host-name/TunnelBuilderPro/clientkit/ServerControl.html
To access the Tunnel Builder Pro from your laptop, use your web browser to find and select the ServerControlLaptop.html file. For example:
http:// server-host-name/TunnelBuilderPro/clientkit/ServerControlLaptop.html
|
Note If you have not previously downloaded and installed the Java Plug-in Version 1.3.1, you may be prompted to do so at this point. |
The Tunnel Builder Pro application is displayed in your browser window.
|
Note When your evaluation software expires, follow the procedures described under "Shutting Down Cisco MPLS Tunnel Builder Pro" and "Stopping the RMI Daemon and the BRG Server". |
You need to reinstall the Cisco MPLS Tunnel Builder software to do any of the following upgrades:
To shut down Tunnel Builder Pro, locate the Tunnel Builder Server process on the machine and kill the process ID.
To locate the process IDs for the Tunnel Builder server, enter the following command:
ps -ef | grep serverkit
Once the process ID is found, enter this command:
kill -9 process-id
You can use the following arguments in the BRG install.sh script that is found in the installation-directory/serverkit/installed/bin directory:
When invoked without options, install.sh assumes the "r" argument; that is, it stops the server, clears the log file, and then restarts the server.
The instructions for manually shutting down and restarting the server follow.
In its default state, the install script cleans the contents of any existing log directory.
The directory log contains the configuration of the RMI Daemon that is persistent from one start of the daemon to another. If the port is changed, remove the log directory.
To stop the RMI Daemon and the BRG server without starting a new installation, do the following from the serverkit/installed subdirectory of the installation directory:
./bin/install.sh -k
./bin/install.sh -k ABCD
The Tunnel Builder Pro installation process automatically starts the BRG server if you have the appropriate license. Restarting the BRG server is usually unnecessary, but after an incident such as a machine reboot, you need to restart it.
To start the RMI Daemon and the BRG server, run the script install.sh as follows:
$ su root
password: password
$ cd installation-directory/serverkit/installed
$ ./bin/install.sh -p data/system.properties -Djava.security.policy=data/server.policy
ABCD
where installation-directory is the directory in which Tunnel Builder Pro was installed and ABCD is the RMI port chosen at installation time. It must match the RMI port specified in the serverkit/TBconfig.txt file.
Cisco MPLS Tunnel Builder Pro Version 2.1 includes the following new features:
|
Note The Cisco IOS image that supports SSH will support Data Encryption Standard (DES)
encryption or DES and Triple DES (3DES) encryption. In the DES software images, DES is the
only encryption algorithm available. In the 3DES software images, both DES and 3DES
encryption are available. If the seed router supports both DES and 3DES data encryption, then all routers on the network must be loaded with an image that supports DES and 3DES data encryption. In this case, by default, the seed router uses 3DES encryption. If the seed router supports only DES data encryption, then all routers on the network can be loaded with an image that supports DES only or with an image that supports both DES and 3DES data encryption. A router that supports DES and 3DES understands the DES encryption sent by the seed router. |
