Border Gateway Protocol (BGP) VPNs Layer 3 VPN over Multiprotocol Label Switching (MPLS) is the most widely deployed MPLS application in Service Provider and self-managed Enterprise networks. The Cisco IOS Software implementation of this architecture (RFC 2547) provides secure control and forwarding planes upon which to build robust VPNs.
What is BGP? Border Gateway Protocol (BGP) is the postal service of the Internet. When someone drops a letter into a mailbox, the postal service processes that piece of mail and chooses a fast, efficient route to deliver that letter to its recipient. OpenStack Docs: BGP VPN Interconnection Service Overview BGP VPN are deployed, and managed by the operator, in particular to manage Route Target identifiers that control the isolation between the different VPNs. Because of this BGP VPN parameters cannot be chosen by tenants, but only by the admin. In addition, network operators may prefer to not expose actual Route Target values to the users.

BGP enables the Azure VPN Gateways and your on-premises VPN devices, called BGP peers or neighbors, to exchange "routes" that will inform both gateways on the availability and reachability for those prefixes to go through the gateways or routers involved.
