Associating or disassociating subnet for a multicast domain
Associate a subnet with a multicast domain​
tip​
  • Before associating a subnet, ensure that the Virtual Private Cloud (VPC) to which the subnet belongs has established an Network Instance Attachment with the Transit Router (TR) instance.​
  • A single multicast domain supports associating a maximum of 10 subnets by default. If the default quota is insufficient, see create a quota application to submit a quota increase request.​
  1. Click the name of the target TR instance.​
  1. In the zone below Basic information, select the Multicast domain tab.​
  1. Click the name of the target multicast domain.​
  1. Click Associate subnet, and sequentially select the VPC and subnet.​
  1. Click Associate to complete the action.​
Disassociate a subnet from a multicast domain​
tip​
  • Before disassociating a subnet, ensure that no multicast sources or multicast members belong to the subnet. If any, delete the multicast sources and multicast members first. For procedure, see Delete a multicast source and Delete a multicast member.​
  • When deleting a subnet in the VPC console, subnets already associated with a multicast domain are automatically disassociated.​
  1. Click the name of the target TR instance.​
  1. In the zone below Basic information, select the Multicast domain tab.​
  1. Click the name of the target multicast domain.​
  1. Click Disassociate to the right of the target subnet.​
  1. Click Disassociate to complete the action.​
