Installing the MPLS/VPN BGP LEG Software

SUMMARY STEPS

1. Copy the SM LEG distribution file to the SM machine and extract it with the gunzip command.

2. Run the BGP LEG installation script.

3. Add a VCS resource for the BGP LEG

DETAILED STEPS

Step 1 Copy the SM LEG distribution file to the SM machine and extract it with the gunzip command.

>gunzip SM_LEG_3.1.0_Bbbb.tar.gz >tar -xvf SM_LEG_3.1.0_Bbbb.tar.gz >cd bgp_leg
Step 2 Run the BGP LEG installation script.

#/install-bgp-leg.sh
The installation script automatically installs the SM MPLS/VPN BGP LEG on the SM and runs the OS specific definitions scripts according to your installation's operating system.

Note The installation script must run under root privileges.

Step 3 Add a VCS resource for the BGP LEG

Adding a VCS Resource to the BGP LEG

In a Subscriber Manager cluster topology, the Veritas Cluster Server (VCS) should monitor the BGP LEG process to verify that the process is running. To do so, you must configure the VCS with a resource that monitors and controls the LEG.

SUMMARY STEPS

1. Import the OnOnlyProcess agent's type from file:

/opt/VRTSvcs/bin/OnOnlyProcess/OnOnlyProcess.cf

2. Add an OnOnlyProcess resource called "BGP_LEG" to the service group.

3. Run the >ps -ea -o pid,s,args command via telnet on each one of the servers.

4. Look for the line containing "bgpleg" in the text.

5. Define the OnlineCmd, PathName, and Arguments parameters:

6. Click OK.

DETAILED STEPS

Step 1 Import the OnOnlyProcess agent's type from file:

/opt/VRTSvcs/bin/OnOnlyProcess/OnOnlyProcess.cf

Step 2 Add an OnOnlyProcess resource called "BGP_LEG" to the service group.

Step 3 Run the >ps -ea -o pid,s,args command via telnet on each one of the servers.

Step 4 Look for the line containing "bgpleg" in the text.

This line contains the path and arguments of the BGP LEG to be used in the next step.

Step 5 Define the OnlineCmd, PathName, and Arguments parameters:

•OnlineCmd—Type the BGP LEG start command, for example:

/opt/pcube/sm/server/bin/p3bgp --start

•PathName—Type the BGP LEG process path (from the previous step), for example:

/opt/pcube/sm/server/addons/bgpleg/bgpleg

•Arguments—Type the BGP LEG process arguments (from the previous step). For example:

-launch /opt/pcube/sm/server/root/config/p3bgpleg.cfg
Step 6 Click OK.

Figure 2-1 shows the Add Resource window.

Note The arguments line might seem shorter than the actual full argument value, which is perfectly acceptable.

Removing a VCS Resource from the BGP LEG

Step 1 Right-click the BGP LEG resource icon you want to remove.

Step 2 From the drop-down list shown in Figure 2-2, choose Delete.

Figure 2-2 Removing a VCS Resource

Note The BGP LEG will be inactivated if there are no VCS resources. To activate the BGP LEG, there must be at least one resource.
