Description

VPC

Not supported
  • Auto creation: If Default Route Table Association is enabled and the default association route table is specified, attachments are automatically associated with the default association route table.
  • Manual creation: You can select a route table and create an association in it to associate an attachment with the route table. For details, see Creating an Association for an Attachment in a Route Table.

Each attachment can only be associated with one route table. Associations between attachments in Association Overview are described as follows:

  • Auto creation: The system automatically associates attachments, such as VPC 1, VPC 2, and virtual gateway 1 attachments, with the default route table of the enterprise router.
  • Manual creation: You need to manually create associations in the custom route table of the enterprise router for attachments, such as VPC 3, VPC 4, and virtual gateway 2 attachments.
