Status codes
|
Status of the table entry. The status is displayed as a three-character field at the beginning of each line in the table.
The first character may be (in order of precedence):
S—Path is stale, indicating that a graceful restart is in progress with the peer from which the route was learned.
s—Path is more specific than a locally sourced aggregate route and has been suppressed.
*—Path is valid.
The second character may be (in order of precedence):
>—Path is the best path to use for that network.
d—Path is dampened.
h—Path is a history entry, representing a route that is currently withdrawn, but that is being maintained to preserve dampening
information. Such routes should never be marked as valid.
The third character may be:
i—Path was learned by an internal BGP (iBGP) session.
|
|
Origin codes
|
Origin of the path. The origin code is displayed at the end of each line in the table. It can be one of the following values:
i—Path originated from an Interior Gateway Protocol (IGP) and was advertised with a network or

|
|
LocPrf
|
Local preference value. This is used to determine the preferred exit point from the local autonomous system. It is propagated

|
|
Weight
|
Path weight. Weight is used in choosing the preferred path to a route. It is not advertised to any neighbor.
|
|
Path
|
Autonomous system path to the destination network. At the end of the path is the origin code for the path.

i—Path originated from an Interior Gateway Protocol (IGP) and was advertised with a network or
aggregate-address
command.
e—Path originated from an Exterior Gateway Protocol (EGP).
?—Origin of the path is not clear. Usually, this is a route that is redistributed into BGP from an IGP.
|
|
Network
|
IP prefix and prefix length for a network.
|
|
From
|
Neighbor from which the route was received.
|
