What Are the Differences Between 5_bgp, 5_mailbgp, and 5_gray EIPs?

Application scenario

Dynamic BGP provides automatic failover and chooses the optimal path when a network connection fails.

5_bgp EIPs can be bound to cloud resources except dedicated load balancers.

5_gray EIPs are no longer supported.

5_mailbgp EIPs are used together with port 25, 465, or 587 for email services.

Differences

• Cannot be used for email services.
• Can be bound to dedicated and shared load balancers.

• Not suggested to be bound to dedicated or shared load balancers by default.
• Cannot be used for email services.

• Cannot be bound to dedicated load balancers.
• Can be used for email services.

Constraints

The selected EIP type cannot be changed after the EIP is assigned.

• In eu-de, existing 5_gray EIPs cannot be bound to dedicated or shared load balancers. You can use 5_bgp EIPs instead.
• In eu-de, no more new EIPs of this type can be assigned. You can assign EIPs of the BGP (5_bgp) type.

If you need an EIP of this type, contact the account administrator to grant the required permissions.
