With PW routing configured on T-PEs and S-PEs, and spoke SDP FECs configured on the T-PEs, the NE will establish the pseudo-wires between T-PEs. This includes creating switching sites between two T-PEs. A switching site for MS-PW is a read-only site (nothing can be modified) and it cannot be deleted. It is controlled by the NE.

Use the following method to discover such sites.

Note: The switching sites and spoke SDP bindings created by MS-PW routing are tagged with their Creation Mode attribute indicating Multi-Segment PW (as opposed to Manual for non-MS-PW entities).

When a switching site is discovered, the associated spoke SDP bindings under it are also discovered and re-synced. The NFM-P will create a composite service and connector(s) if there are matching spoke SDP bindings found in other Epipe services (based on cross-matching of the spoke SDP ingress/egress labels). The related service is added to the newly-created composite service.
