To configure an MVPN VRF instance on a VPRN site

Before you begin

For 7750 SR, 7450 ESS, and 7950 XRS NEs starting in Release 16.0 R1, PIM must be enabled before MVPN can be configured; see To enable routing protocols on a VPRN site. If PIM is disabled, MVPN configuration is removed.

Steps
 
1 

Choose Manage→Service→Services from the NFM-P main menu. The Manage Services form opens.

2 

Choose a VPRN service and click Properties. The VPRN Service (Edit) form opens.

3 

On the service navigation tree, expand the Sites icon, right-click on a routing instance and choose Properties. The VPRN Site (Edit) form opens.

If the site you are configuring is a 7210 SAS-R, you must configure the device properties. See To configure 7210 SAS-R device properties for MVPN.

4 

Click on the Multicast tab, the MVPN tab, then the Routing tab.

5 

Configure the MVPN VRF Target Type parameter:

Note: Route targets are used to identify the VRFs of a VPRN. A PE router that is not a route reflector or an AS border router installs a VPRN route only when its import target matches the target of the route.

A fully-meshed VPRN requires one target for all participating VRFs. A hub-and-spoke VPRN requires VRF import and export targets. The export target of the hub VRF must be the same as the import target of the spoke VRFs. The import target of the hub VRF must be the same as the export target of the spoke VRF. VPRN VRF targets must not overlap.

  1. If you do not need to specify a VRF target for the site, set the MVPN VRF Target Type parameter to None. Go to Step 9 .

  2. If you need to specify a default VRF target for the site, set the MVPN VRF Target Type. Go to Step 6 .

  3. If you need to specify import and export VRF targets for the service site, set the MVPN VRF Target Type parameter to Define Import and Export. Go to Step 7 .

Configure the Target Format parameter by performing one of the following steps:

  1. To specify a two-byte AS number for the default target:

    1. Configure the required parameters.

      • Target AS Value

      • Target Extended Community Value

      The Target AS Value is the Autonomous System number of the PE node. For the Target Extended Community Value, the NFM-P assigns the next unused number within the valid range. When all of the numbers within the valid range have been used once, the system starts at the beginning of the range and assigns the next available number.

    2. Go to Step 11 .

  2. To specify an IP Address for the default target:

    1. Configure the required parameters.

      • Target IP Address

      • Target Community Value

    2. Go to Step 11 .

  3. To specify a four-byte AS number for the default target:

    1. Configure the required parameters.

      • Target AS Value (4Byte)

      • Target Community Value

      The Target AS Value (4Byte) is the Autonomous System number of the PE node. For the Target Community Value, the NFM-P assigns the next unused number within the valid range. When all of the numbers within the valid range have been used once, the system starts at the beginning of the range and assigns the next available number.

    2. Go to Step 11 .

7 

Configure the Import Target Format parameter by performing one of the following steps:

  1. Choose None to specify no VRF import target format for the site, then go to Step 8 .

  2. Choose AS as the two-byte import target format for the site.

    1. Configure the required parameters.

      • Import Target AS Value

      • Import Target Extended Community Value

      The Import Target AS Value is the two-byte Autonomous System number of the PE node. For the Import Target Extended Community Value, the NFM-P assigns the next unused number within the valid range. When all of the numbers within the valid range have been used once, the system starts at the beginning of the range and assigns the next available number.

    2. Go to Step 8 .

  3. Choose IP Address as the import target format for the site.

    1. Configure the required parameters.

      • Import Target IP Address

      • Import Target Community Value

    2. Go to Step 8 .

  4. Choose AS-4Byte as the four-byte import target format for the site.

    1. Configure the required parameters.

      • Import Target AS Value (4Byte)

      • Import Target Community Value

      The Import Target AS Value (4Byte) is the four-byte Autonomous System number of the PE node. For the Import Target Community Value, the NFM-P assigns the next unused number within the valid range. When all of the numbers within the valid range have been used once, the system starts at the beginning of the range and assigns the next available number.

    2. Go to Step 8 .

8 

Configure the Export Target Format parameter by performing one of the following steps:

  1. Choose None to specify no VRF export target format for the site, then go to Step 9 .

  2. Choose AS as the two-byte export target format for the site.

    1. Configure the required parameters.

      • Export Target AS Value

      • Export Target Extended Community Value

      The Export Target AS Value parameter is the two-byte Autonomous System number of the PE node. For the Export Target Extended Community Value, the NFM-P assigns the next unused number within the valid range. When all of the numbers within the valid range have been used once, the system starts at the beginning of the range and assigns the next available number.

    2. Go to Step 9 .

  3. Choose IP Address as the export target format for the site.

    1. Configure the required parameters.

      • Export Target IP Address

      • Export Target Community Value

    2. Go to Step 9 .

  4. Choose AS-4Byte as the four-byte export target format for the site.

    1. Configure the required parameters.

      • Export Target AS Value (4Byte)

      • Export Target Community Value

      The Export Target AS Value (4Byte) parameter is the four-byte Autonomous System number of the PE node. For the Export Target Community Value, the NFM-P assigns the next unused number within the valid range. When all of the numbers within the valid range have been used once, the system starts at the beginning of the range and assigns the next available number.

    2. Go to Step 9 .

To configure import policies:

  1. Click on the Import Policies tab and set the Import Unicast parameter to False.

  2. Select the required unicast import policies 1 through 15. You can use the Select button to choose a single policy, or click on the Create Expression button to use a logical expression, as described in To create a BGP policy expression.

10 

To configure export policies:

  1. Click on the Export Policies tab and set the Export Unicast parameter to False.

  2. Select the required unicast export policies 1 through 15. You can use the Select button to choose a single policy, or click on the Create Expression button to use a logical expression, as described in To create a BGP policy expression.
