This section provides a brief overview of the tasks that must be performed to configure SDPs and provides the CLI commands.
Consider the following SDP characteristics:
SDPs can be created as either GRE or MPLS.
Each distributed service must have an SDP defined for every remote router to provide VLL, VPLS, and VPRN services.
A distributed service must be bound to an SDP. By default, no SDP is associated with a service. After an SDP is created, services can be associated with that SDP.
An SDP is not specific or exclusive to any one service or any type of service. An SDP can have more than one service bound to it.
The SDP IP address must be an Nokia router system IP address.
To configure an MPLS SDP, LSPs must be configured first and then the LSP-to-SDP association must be explicitly created. Auto-LSPs such as one-hop-p2p and mesh-p2p, and PCE initiated LSPs cannot be used by a configured MPLS SDP.
In the SDP configuration, automatic ingress and egress labeling (targeted LDP) is enabled by default. Ingress and egress VC labels are signaled over a TLDP connection between two Nokia nodes.
If signaling is disabled for an SDP, then services using that SDP must configure ingress and egress vc-labels manually.
To configure a basic SDP, perform the following steps:
