If a spoke SDP in endpoint "Y", including the ICB spoke SDP, received T-LDP SAP down status
bits, and/or received T-LDP SDP-binding down status bits, and/or received status bits of
pseudowire not forwarding, the node saves this status and takes no further action. The saved status
is used for selecting the active transmit endpoint object.
If all objects in endpoint "Y", except the ICB spoke SDP, transition locally to down state, and/or
received T-LDP SAP down status bits, and/or received T-LDP SDP-binding down status bits, and/
or received status bits of pseudowire not forwarding, the node must send status bits of SDP-
binding down over the "X" endpoint ICB spoke SDP only.
If all objects in endpoint "Y" transition locally to down state, and/or received T-LDP SAP down
status bits, and/or received T-LDP SDP-binding down status bits, and/or received status bits of
pseudowire not forwarding, the node must send status bits of SDP-binding down over the "X"
endpoint ICB spoke SDP, and must send a SAP down notification on the "X" endpoint SAP by the
SAP specific OAM signal if applicable. An Ethernet SAP does not support signaling status
notifications.
