Installing and Starting Cisco MPLS Tunnel Builder Pro

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 license key (or hit return if evaluation option). 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. 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] 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] 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 access 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

The Tunnel Builder Pro application is displayed in your browser window.


Reinstallation Requirements for Upgrading

You need to reinstall the Cisco MPLS Tunnel Builder software to do any of the following upgrades:

Shutting Down Cisco MPLS Tunnel Builder Pro

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

Stopping and Restarting the BRG Server

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.

Stopping the RMI Daemon and the BRG Server

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
where ABCD is the port number.

Restarting the RMI Daemon and the BRG Server

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.

Features of Cisco MPLS Tunnel Builder Pro

Cisco MPLS Tunnel Builder Pro includes the following features:

Caveats

Caveats describe unexpected behavior in Cisco MPLS Tunnel Builder Pro software releases. Severity 1 caveats are the most serious; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only selected severity 3 caveats are included in caveats documentation.

Open Caveats—Cisco MPLS Tunnel Builder Pro

This section describes possible unexpected behavior by Cisco MPLS Tunnel Builder Pro. This section describes only severity 1, severity 2, and selected severity 3 caveats. This release contains no severity 1, or severity 2 caveats.

The ../serverkit/SeedRouters.txt file is overwritten during an upgrade of an existing TunnelVision installation.

Workaround: Back up the existing SeedRouters.txt file and copy it back into the ../serverkit directory after an installation upgrade is performed.

All the links and or nodes selected in the topology map that is every element is green and red. If you click a link or node and try to deselect it, the node or link stays or becomes selected and the original selected links or nodes are greyed out.

Workaround: There is no workaround.

In the Links tab of Tunnel Builder Pro, the user can enter a value of 0 for max global reservable and max subpool reservable. However, when you click the Modify button, the link is not changed so that no bandwidth is reserved by RSVP.

This is because the ip rsvp bandwidth 0 0 sub 0 command is sent to Cisco IOS. Cisco IOS rejects this as invalid. The no ip rsvp bandwidth command in Cisco IOS would cause the link to not allow any bandwidth to be reserved. Tunnel Builder Pro does not generate this command.

Workaround: Manually enter the no ip rsvp bandwidth command on the router.

The autoroute announce field in the Tunnels panel front pane is editable (whether it is checked or not). The autoroute announce field should be read only.

Workaround: There is no workaround. The field has no impact whether you check it or not from this pane.

Occasionally, BRG returns a time out status before the time-out duration is reached when you perform a "Create Backups" on a set of routers in a network.

Workaround: Run "Create Backups" on the affected routers separately and the problem should not occur.
