Can Multiple EIPs Be Bound to an ECS?

Scenarios

Multiple EIPs can be bound to an ECS, but this operation is not recommended.

If you really need to bind multiple EIPs to an ECS, you must manually configure routing policies, which requires high network skills. Exercise caution when performing this operation.

Configuration Example

Table 1 lists ECS configurations.

Example 1:

Example 2:

Based on example 1, if you are required to enable routing for default public network traffic through standby NIC eth1, perform the following operations to configure a route:

1. Log in to the ECS.
2. Run the following command to delete the default route:

   ip route delete default

   

   Exercise caution when deleting the default route because this operation will interrupt the network and result in SSH login failures.

3. Run the following command to configure a new default route:

   ip route add 0.0.0.0/0 dev eth1 via 192.168.2.1

   In the preceding command, 192.168.2.1 is the gateway IP address of standby NIC eth1.
