How do I create services on SDPs with multiple loopback addresses?

Creating services on SDPs with multiple loopback addresses

NSP supports the configuration of services on SDP tunnels using a loopback IP address as either the source or destination IP address when routing services. A potential benefit of having services on SDP tunnels using a loopback IP address is the ability to configure routing on tunnels established on different paths between two NEs. However, you can configure such services only on brownfield SDP tunnels that were created in NFM-P or on NEs. NSP does not support the creation of new service tunnels using loopback IP addresses.

Before you start configuring a service in NSP, you must create SDP tunnels with loopback IP addresses in NFM-P or on the NE. The following list captures the high-level configuration tasks required for each NE.

Configure the loopback interfaces on routers.
Configure peers on the targeted LDPs. Use the loopback interface name as the local-lsr-id option and enable tunneling to enable LDP over the tunnels.
Configure the SDP tunnels using the loopback interface IP addresses for the service far end. Optionally, you can apply a steering parameter to the tunnel to help the selection of the correct SDP tunnel when creating the service.

The service tunnels that you created can be viewed on the Service Management, Service Tunnels view. The service tunnel Destination IP is the IP address of the loopback interface and the service Transport type is MPLS.

If you applied the optional steering parameter to the tunnel, then you can also create a tunnel selection policy for the steering parameter.
