This section describes the various identifiers used on the 1830 PSS that are relevant to configuring the GMPLS UNI on the 7750 SR or 7950 XRS node in conjunction with the 1830 PSS. Figure 1 illustrates the identifier architecture of a 1830 PSS multi-shelf system. The multi-shelf system consists of a control plane node and one or more data plane nodes. The following identifiers are used:
GMRE node IP— This is the IP loopback address used for GMPLS protocols such as LMP and RSVP.
IPCC IP address (also known as DcnGatewayAddress)— This is the source/destination address for IPCC maintenance messages such as LMP hellos and LMP config messages. When only one IPCC exists between a 7750 SR or 7950 XRS and 1830 PSS pair, this may be the same as the IP management loopback.
CP Node ID — This is a non-routable identifier for the control plane node. It is used for identifying this node in the optical domain; for example, the session/sender template. It is also used in the RSVP ERO to identify the 1830 PSS node.
DP Node ID — This is a non-routable identifier for a data plane node. This identifies a particular data plane shelf in the optical domain.
TE Link IDs — The TE Link ID is unique across a set of DP and CP nodes forming an 1830 PSS.
