Displaying the Routes BGP4 Has Placed in the IP Route Table
The IP route table indicates the routes it has received from BGP4 by listing “BGP” as the route type.
To display the IP route table, enter the following command:
FESX424 Router# show ip route
Syntax: show ip route [<ip-addr> | <num> | bgp | ospf | rip]
Cluster List The route-reflector clusters through which this set of attributes has
passed.
Aggregator Aggregator information:
• AS Number shows the AS in which the network information in the
attribute set was aggregated. This value applies only to
aggregated routes and is otherwise 0.
• Router-ID shows the router that originated this aggregator.
Atomic Whether the network information in this set of attributes has been
aggregated and this aggregation has resulted in information loss.
• TRUE – Indicates information loss has occurred
• FALSE – Indicates no information loss has occurred
Note: Information loss under these circumstances is a normal part of
BGP4 and does not indicate an error.
Local Pref The degree of preference for routes that use this set of attributes
relative to other routes in the local AS.
Communities The communities that routes with this set of attributes are in.
AS Path The ASs through which routes with this set of attributes have passed.
The local AS is shown in parentheses.
