show ip bgp routes detail output descriptions (continued)
This field
Displays
NOTE
If the "m" is lowercase, the software was not able to install the
route in the IP route table.
•
S - SUPPRESSED. This route was suppressed during
aggregation and thus is not advertised to neighbors.
Age
The last time an update occurred.
Next_Hop
The next-hop device for reaching the network.
Learned from Peer
The IP address of the neighbor that sent this route.
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.
