Benefits​

  • Enables a secure and private connection by directly linking on-premises and Azure environments without going through the public internet.
  • Allows for clear management of Primary and Secondary lines through the simple UI of the OCX Portal.

Notes​

Unlike other cloud services, Azure uses Q-in-Q (IEEE 802.1ad) for its packet protocol. Therefore, the router on the on-premises side must be compatible with Q-in-Q.
