Configuring an SDP

The most basic SDP must have the following:

SDP Configuration Tasks

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:

To configure a basic SDP, perform the following steps:
1. Specify an originating node.
2. Create an SDP ID.
3. Specify an encapsulation type.
4. Specify a far-end node.

A locally unique SDP identification (ID) number.
The system IP address of the originating and far-end 7750 SR routers.
An SDP encapsulation type - either GRE or MPLS.
SDPs can be created as either GRE or MPLS.
Each distributed service must have an SDP defined for every remote 7750 SR-Series
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. Once an SDP is created, services can be associated to 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 a 7750 SR-Series system IP address.
In order to configure an MPLS SDP, LSPs must be configured first and then the LSP-to-
SDP association must be explicitly created.
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 7750 SR-Series routers.
Note that if signaling is disabled for an SDP, then services using that SDP must configure
ingress and egress vc-labels manually.
