Configuring BGP4
December 2005 © Foundry Networks, Inc. 21 - 95
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 – 4294967295.
MED The route’s 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 this set of attributes came to BGP through
EGP.
• IGP – The routes with this set of attributes came to BGP 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 a destination to select the
best route, IGP is preferred over EGP and both are preferred over
INCOMPLETE.
Weight The value that this router associates with routes from a specific
neighbor. For example, if the router receives routes to the same
destination from two BGP4 neighbors, the router 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 router that originated this aggregator.
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 Layer 3 Switch 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.
