Global Export Maps

You can use a global export map to change the attributes of a route when it is exported
from a VRF to the global BGP non-VPN RIB local to the VR.
If the VRF route matches the export map, then the route is exported and the attributes
are changed as specified in the export map. If the VRF route does not match the export
map, then the route is not exported. If you do not configure a global export map, then no
routes are exported from the VRF to the global BGP non-VPN RIB.
Routes that are imported into the VRF cannot be exported again. As a consequence, VPN
routes can be injected only into the global IP routing table on the PE router that is directly
connected to the CE router that originates the prefix.
See "Global Export of IPv6 VPN Routes into the Global BGP IPv6 RIB" on page 436 for
information about global export maps and IPv6 VPNs.
Use to apply a route map to a VRF to modify and filter routes exported by the VRF to
the global BGP non-VPN RIB in the parent VR.
You can specify that only IPv4 or only IPv6 routes are exported. By default, both types
of routes are exported.
Example
host1:boston(config-vrf)#global export map routemap14
Use the no version to disable the exporting of routes to the global BGP non-VPN RIB.
See global export map.

Import Maps

You can use an import map to change the attributes of a route when it is imported from
the global BGP VPN RIB to a VRF. You can also use an import map to filter routes. If you
associate an import map with a VRF, that VRF then accepts only received routes that
pass the import map (and match the import route target list).
Use to apply an import route map to a VRF to modify and filter routes imported to the
BGP RIB of the VRF from the global BGP VPN RIB in the parent VR.
You can specify that only IPv4 or only IPv6 routes are imported. By default, both types
of routes are imported.
Example
host1:boston(config-vrf)#import map routemap72
Use the no version to remove the route map from the VRF.
See import map.
