Whether multiple primary NEs that function similar to gateway NEs can be created in an ASON domain

Only one primary NE and one secondary NE can be created in an ASON domain. The U2000 server needs to establish a connection with either the primary or secondary NE. The NE that establishes a connection with the U2000 is called the gateway NE and implements communication between the ASON network and the U2000 server. In normal cases, you are advised to configure the primary NE as the communication 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.
