Origin attribute of route, which indicates that the route updates its
origin relative to the route originating it from AS. It has three optional
values:
IGP The route belongs to inside of AS. BGP treats aggregate
route and the route defined by the command network as
inside of AS, and origin type as IGP.
EGP The route is learned from exterior gateway protocol (EGP).
Origin
INC
Short for INCOMPLETE: indicates that the original source
of the route information is unknown (learned by other
methods). BGP sets the origin of the route imported through
other IGP protocols as INCOMPLETE
As-path AS-path attribute of route, which records all AS areas that the route
passes. With it, route loop can be avoided
