Description
Enables BGP to export routes from other protocols to BGP peers.
Syntax Description
Default
Disabled.
Usage Guidelines
The exporting of routes between any two routing protocols is a discreet configuration function. For
example, you must configure the switch to export routes from OSPF to BGP and, if desired, you must
configure the switch to export routes from BGP to OSPF. You must first configure both protocols and
then verify the independent operation of each. Then, you can configure the routes to export from OSPF
to BGP, and the routes to export from BGP to OSPF. Similarly for BGP and ISIS, or BGP and RIP.
You can use route maps to associate BGP attributes including Community, NextHop, MED, Origin, and
Local Preference with the routes. Route maps can also be used to filter out exported routes.
Using the
export
command to redistribute routes complements the redistribution of routes using the
configure bgp add network
command. The
configure bgp add network
command adds the route
to BGP only if the route is present in the routing table. The
enable bgp export
command redistributes
an individual route from the routing table to BGP. If you use both commands to redistribute routes, the
routes redistributed using the
network
command take precedence over routes redistributed using the
export
command.
