Displaying BGP4 information
Table 71 lists the field definitions for the command output.
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.
Brocade#show ip route
Syntax: show ip route [ip-addr | num | bgp | ospf | rip]
Here is an example of the information displayed by this command. Notice that most of the routes in
this example have type “B”, indicating that their source is BGP4.
TABLE 71 BGP4 route-attribute entries information
Field Description
Total number of BGP Attribute
Entries The number of routes contained in this router BGP4 route table.
Next Hop The IP address of the next hop router for routes that have this set of attributes.
Metric The cost of the routes that have this set of attributes.
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.
Originator The originator of the route in a route reflector environment.
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 autonomous systems through which routes with this set of attributes have
passed. The local AS is shown in parentheses.
