Displaying BGP4 information

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 – 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.
