The BGP_ASN_RANGE structure<185> is used to represent an autonomous system number (ASN) range.

 typedef struct _BGP_ASN_RANGE {
   DWORD dwStartRange;
   DWORD dwEndRange;
 } BGP_ASN_RANGE,
  *PBGP_ASN_RANGE;

dwStartRange: Specifies the first ASN in the range. This value MUST be between 1 and 65534.

dwEndRange: Specifies the last ASN in the range. This value MUST be greater than or equal to dwStartRange. This value MUST be between 1 and 65534.
