If you want two attachments of an enterprise router to learn routes from each other, the router and each attachment must have a unique ASN. In this way, the enterprise router advertises the learned route information between the attachments.

If you want a global DC gateway and a VPN gateway attached to an enterprise router to learn routes from each other, their ASNs can be as follows:

Enterprise router: 64525
Global DC gateway attachment: 64512 (BGP ASN of the global DC gateway)
VPN gateway attachment: 64515 (BGP ASN of the VPN gateway)

NOTE:

VPC attachments do not support route learning.
