This field Displays
Local_Pref The degree of preference for this route relative to other routes in the local AS. When the
BGP4 algorithm compares routes on the basis of local preferences, the route with the
higher local preference is chosen. The preference can have a value from 0 through
4294967295.
MED The route metric. If the route does not have a metric, this field is blank.
Origin The source of the route information. The origin can be one of the following:
• EGP - The routes with these attributes came to BGP4 through EGP.
• IGP - The routes with these attributes came to BGP4 through IGP.
• INCOMPLETE - The routes came from an origin other than one of the above. For
example, they may have been redistributed from OSPF or RIP.
When BGP4 compares multiple routes to select the best route, IGP is preferred over EGP
and both are preferred over INCOMPLETE.
Weight The value this device associates with routes from a specific neighbor. For example, if the
device receives routes to the same destination from two BGP4 neighbors, the device
prefers the route from the neighbor with the larger weight.
Atomic Whether network information in this route has been aggregated and this aggregation has
resulted in information loss.
NOTE
Information loss under these circumstances is a normal part of BGP4 and does not
indicate an error.
Aggregation ID The device that originated this aggregation.
Aggregation AS The AS in which the network information was aggregated. This value applies only to
aggregated routes and is otherwise 0.
Originator The originator of the route in a route reflector environment.
Cluster List The route-reflector clusters through which this route has passed.
Learned From The IP address of the neighbor from which the device learned the route.
Admin Distance The administrative distance of the route.
Adj_RIB_out The number of neighbors to which the route has been or will be advertised. This is the
number of times the route has been selected as the best route and placed in the Adj-RIB-
Out (outbound queue) for a BGP4 neighbor.
Communities The communities the route is in.
