Redistribute
The redistribute attach point allows routes from other sources to be advertised by BGP. The policy attached
at this point is able to set any of the valid BGP attributes on the routes that are being redistributed. Likewise,
selection operators allow a user to control what route sources are being redistributed and which routes from
those sources.
The following example shows how to redistribute all routes from OSPF instance 12 into BGP. If OSPF were
carrying a default route, it is dropped. Routes carrying a tag of 10 have their local preference set to 300 and
the community value of 2:666 and no-advertise attached. All other routes have their local preference set to
200 and a community value of 2:100 set.

Show BGP
The show bgp attach point allows the user to display selected BGP routes that pass the given policy. Any
routes that are not dropped by the attached policy are displayed in a manner similar to the output of the show
bgp command.
In the following example, the show bgp route-policy command is used to display any BGP routes carrying
a MED of 5:
