aa:nn: Specifies a community number. It can be input up to 13 times.

Origin 

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). 

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
