Table or Object (or index)
Description
cbgpRouteOrigin
The ultimate origin of the route information.
cbgpRouteASPathSegment 
The sequence of autonomous system path segments.
cbgpRouteNextHop
The network layer address of the autonomous system 
border router that traffic should pass through to get to 
the destination network.
cbgpRouteMedPresent
Indicates that the MULTI_EXIT_DISC attribute for 
the route is either present or absent.
cbgpRouteMultiExitDisc 
Metric that is used to discriminate between multiple 
exit points to an adjacent autonomous system. The 
value of this object is irrelevant if the value of the 
cbgpRouteMedPresent object is “false(2).”
cbgpRouteLocalPrefPresent
Indicates that the LOCAL_PREF attribute for the route 
is either present or absent.
cbgpRouteLocalPref Determines 
the 
degree of preference for an advertised 
route by an originating BGP speaker. The value of this 
object is irrelevant if the value of the 
cbgRouteLocalPrefPresent object is “false(2).”
cbgpRouteAtomicAggregate
Determines if the system has selected a less specific 
route without selecting a more specific route. 
cbgpRouteAggregatorAS 
The autonomous system number of the last BGP 
speaker that performed route aggregation. A value of 0 
indicates the absence of this attribute.
cbgpRouteAggregatorAddrType 
Represents the type of Network Layer address that is 
stored in the cbgpRouteAggregatorAddr object.
cbgpRouteAggregatorAddr 
The network layer address of the last BGP 4 speaker 
that performed route aggregation. A value of all zeros 
indicates the absence of this attribute.
cbgpRouteBest 
An indication of whether this route was chosen as the 
best BGP 4 route.
cbgpRouteUnknownAttr 
One or more path attributes not understood by the local 
BGP speaker. A size of 0 indicates that this attribute is 
absent.
