Quota limits

The default product quotas are as follows. For quota items that support adjustment, submit a Ticket to request additional quotas.

Category Limitation items Limit value Adjustment supported or not
CSN instance Number of CSNs that can be created under a single account 5 counts Yes
Network instance Number of network instances that can be loaded in a single region under a single CSN instance 10 counts Yes
Number of dedicated channels on the same dedicated channel router that can be loaded under a single CSN instance 1 counts No
Number of CSN instances that a single network instance can be loaded into 1 counts No
Maximum bandwidth limit for a single network instance 100000Mbps Yes
Route table/route Number of route tables that can be created under a single CSN instance 20 counts Yes
Bandwidth package Maximum bandwidth limit of a single bandwidth package in Chinese mainland 10000Mbps Yes
Maximum bandwidth limit of a single cross-border bandwidth package 200Mbps Yes
Number of bandwidth packages of the same connection type that can be bound to a single CSN instance 1 counts No
Number of CSN instances that a single bandwidth package can be bound to 1 counts No
Number of cross-region bandwidths with the same regional combination that can be configured under the same bandwidth package 1 counts No


Other Restrictions

The following limitations apply to routes published by network instances that have established a learning relationship with the same route table:

  • Network segments must not overlap. If they do, it is considered a routing conflict. The first route learned by the route table will be marked as "Available" and take effect, while subsequent conflicting routes will be marked as "Conflict" and will not take effect.
