A. AS path
AS path is a mandatory attribute in BGP that contains the sequence of AS numbers that the route has traversed. It helps prevent routing loops by ensuring that a BGP speaker does not accept a route that contains its own AS number in the AS path attribute. This prevents a BGP speaker from advertising a route back to the AS from which it learned the route, thereby avoiding routing loops in the BGP network.
