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

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

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

To configure an auto-bind tunnel, click on the SDP Binding tab, and then on the Auto-Bind Tunnel tab, and configure the required parameters.

When the Transport parameter is set to MPLS:LDP, you can choose segment routing as a tunnel option by selecting the SR-ISIS or SR-OSPF parameters. The following prerequisites apply:

• Segment routing must be configured; see Segment routing

• You must configure segment routing on the ISIS or OSPF interfaces; see To configure an IS-IS interface and To add a Layer 3 interface to an OSPF router

Configure the Transport parameter:

1. To explicitly specify service tunnels and circuits for the service, set the Transport parameter to None.

2. To automatically bind the service to MPLS service tunnels utilizing MPLS, set the Transport parameter to LDP.

   Note: To use MPLS as the transport type, you must bind LSPs to service tunnels during service tunnel configuration; see To create an IP/MPLS service tunnel

3. To automatically bind the service to MPLS service tunnels using RSVP-LSP, set the Transport parameter to RSVP-LSP.

   Note: The RSVP-LSP option is available only on the 7450 ESS in mixed mode, the 7705 SAR, 7750 SR, and 7950 XRS.

4. To automatically bind the service to MPLS service tunnels using RSVP or LDP, set the Transport parameter to RSVP or LDP.

   This choice provides the ability to simultaneously support both tunnel options, in networks that have a mixture of LDP and RSVP-TE in place. NFM-P always tries to resolve the VPN route by using RSVP-LSP tunnels first (lowest metric). If no RSVP-LSP service tunnels are available, then tunnels configured for LDP are used. If RSVP-LSP tunnels subsequently become available again, then the route resolution automatically returns to RSVP-LSP.

   Note: The RSVP or LDP option is available only on the a 7450 ESS in mixed mode, the 7705 SAR, 7750 SR, or 7950 XRS.

5. To automatically bind the service to GRE service tunnels set the Transport parameter to GRE.

Save the changes and close the forms.
