Item Description
Flags State flags:
# - valid (valid)
^ - best (selected)
D - damped (discarded)
H - history (history)
I - internal (interior gateway protocol)
S - aggregate suppressed (suppressed)
#D The valid and damped route
Dest/Mask The dampened route to the destination network 11.1.0.0
Source The nexthop of the route
Damping-limit The time before dampening turns invalid and the route can be reused.
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
