Parent Topic: Edge Gateway
The number of VPCs that can be associated with an edge gateway depends on the gateway edition: Disassociating VPCs from an Edge Gateway: You can disassociate one or more VPCs from an edge gateway at a time.

This parameter cannot be set if the value of ip_version is 6. gateway_ip String The gateway IP address cannot conflict with IP addresses configured for allocation_pools.
Symptom An ECS cannot ping the gateway of the subnet where the ECS resides. Troubleshooting Locate the fault based on the following procedure.
You can use EIPs, NAT gateways, VPN connections, Direct Connect connections, and load balancers to enable access to or from the Internet. By default, instances in different VPCs cannot communicate with each other.
When a subnet is used, the gateway IP address must be configured for the subnet. A router cannot be added to networks whose provider:network_type is geneve. Only one router can be added to a subnet.
Obtain the IKE policy used by your gateway device. Obtain the IPsec policy used by your gateway device. Obtain the ACL rule used by your gateway device. Check whether your gateway device can communicate with the gateway devices on the cloud.
Also, the VPC is not in use by resources, such as subnets that are in use, custom route tables, ECSs, public NAT gateways, private NAT gateways, VPC endpoints, VPC endpoint services, Direct Connect connections, VPC peering connections, VPNs, and enterprise routers.
Border Gateway Protocol (BGP) is a routing protocol used between autonomous systems (ASs). BGP is the only protocol that can process many connections between unrelated routing domains.
EIPs can be bound to or unbound from ECSs, BMSs, NAT gateways, virtual IP addresses, and load balancers. Each EIP can be used by only one cloud resource at a time.
Constraints Subnet: No IP address in the subnet is being used by other resources, such as virtual IP addresses, elastic network interfaces, supplementary network interfaces, ECSs, SNAT rules of NAT gateways, VPC endpoints, VPC endpoint services, and load balancers.
If the local host communicates with the ECS using NAT, this problem may occur. Run the following command to check whether tcp_tw_recycle is enabled on the ECS: sysctl -a|grep tcp_tw_recycle If the value of tcp_tw_recycle is 1, the function is enabled.
gateway: 10.0.1.1 Obtaining ECS Network Interface Addresses Obtaining Subnet CIDR Blocks and Gateway Addresses Destination IPv4 address: 10.0.2.12 N/A Table 2 lists the information to be collected for a Linux ECS using IPv6.
You can bind EIPs to products such as ECSs, NAT gateways, and load balancers so that these products can use the shared bandwidth. Shared Data Package A shared data package is a prepaid package for public network traffic.
In the Gateway and DNS Information area, view the gateway address of the subnet. Figure 2 Viewing the gateway address of the subnet Step 3: Configure Policy-based Routes for the Extended Network Interface ECS Remotely log in to the ECS.
Failed to complete the request because the server has received an invalid response. 503 Service Unavailable Failed to complete the request because the service is unavailable. 504 Gateway Timeout A gateway timeout error occurred.
Figure 5 Gateway address Check whether the gateway communication is normal: ping Subnet gateway address Example command: ping 172.17.0.1 If the gateway address cannot be pinged, see Why Does My ECS Fail to Communicate at a Layer 2 or Layer 3 Network?
The next hop types of such routes are: VPN gateway Direct Connect gateway Cloud connection To delete these routes, you need to delete the associated network instances first. Routes with the next hop type of cloud container cannot be modified or deleted.
