What is the Origin Code attribute?

Explanation:
Origin tells you how a route entered BGP. It indicates the source of the route’s origin—whether the route was learned from an internal IGP, from an external EGP, or via redistribution (incomplete). This helps the router compare routes to the same prefix and prefer one with a lower-origin type (IGP) over EGP, and both over incomplete, during the decision process. This is distinct from the next-hop attribute (which specifies the next hop to reach the prefix), the AS_PATH length (which counts the ASes the route traversed), and the MED value (which hints at preferred exit points between neighboring ASes).
