Maximum number of enterprise routers that can be created by each account | 1 | Contact customer service. |
Maximum forwarding capability supported by each enterprise router | 100 Gbit/s | Contact customer service. |
Constraints¶
Enterprise routers cannot be used together with virtual IP addresses of VPCs. If virtual IP addresses are used, contact customer service.
Traffic cannot be forwarded from a VPC to the enterprise router that it attached to if you set the destination of a route whose next hop is the enterprise router to 0.0.0.0/0 in the VPC route table and if:
An ECS in the VPC has an EIP bound.
The VPC is being used by ELB, NAT Gateway, VPC Endpoint, or Distributed Cache Service (DCS).
To solve this problem, refer to Why Traffic Can't Be Forwarded from a VPC with a Route Destination of 0.0.0.0/0 to Its Enterprise Router?
The VPC route table does not allow you to add a route whose destination address is 100.64.x.x and next hop is an enterprise router.
To solve this problem, refer to How Do I Route Traffic to 100.64.x.x Through an Enterprise Router?
