   Table 1 Parameter descriptions

   Parameter	Description	Example Value
   Region	Regions are geographic areas that are physically isolated from each other. The networks inside different regions are not connected to each other, so resources cannot be shared across different regions. For lower network latency and faster access to your resources, select the region nearest you. The region selected for the EIP is its geographical location.	N/A
   EIP Type	Dynamic BGP: Dynamic BGP provides automatic failover and chooses the optimal path when a network connection fails.	Dynamic BGP
   Billed By	The following bandwidth types are available: Dedicated: The bandwidth can be used by only one EIP and is suitable for scenarios with light or sharply fluctuating traffic. Shared Bandwidth: The bandwidth can be shared by multiple EIPs and is suitable for scenarios with staggered traffic.	Dedicated
   Bandwidth	The bandwidth size in Mbit/s.	100
   EIP Name	The name of the EIP.	eip-test
   Bandwidth Name	The name of the bandwidth.	bandwidth
   Type	The external network that the EIP connects to.	5_bgp
   Quantity	The number of EIPs you want to purchase.	1
