How Do I Enable Two Attachments of an Enterprise Router to Learn Routes from Each Other?
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 two global DC gateways attached to the same enterprise router to learn routes from each other, their ASNs must be different and can be as follows:
- Enterprise router: 64800
- Global DC gateway attachment A: 64513 (BGP ASN of the global DC gateway A)
- Global DC gateway attachment B: 64515 (BGP ASN of the global DC gateway B)
Note
VPC attachments do not support route learning.
