Whether multiple primary NEs can be managed like GNEs in an ASON domain

You can set only one primary NE and one secondary NE in an ASON domain. The NMS only needs to communicate with one NE on an ASON network. This NE is called the communication NE. It is the NE that represents the ASON network to communicate with the NMS. Usually, the communication NE is the primary NE. When the primary NE fails, the secondary NE becomes the communication NE. If both the primary and secondary NEs fail, the system automatically selects an ASON NE as the communication NE.
