Sample Oracle SD-WAN Edge site after replacing the CE Router with the Oracle APNA.

The CE router is removed and the Oracle APNA peers directly with the PE router via eBGP by masquerading its AS number as the replaced CE router's AS number (AS 65200). The APNA's actual Local AS number is 65500 and it can peer via iBGP with local routers in this AS.

If desired, APNAs can also peer with each other via iBGP over a Conduit. This allows Edge to act as an Autonomous System. The primary use-case intended for Edge as an Autonomous System consists of the primary NCN, and secondary NCN if required, are configured as Route-Reflectors, and Clients using an iBGP peering session to the NCN(s) for BGP reachability information.
