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 432
for information about global export maps and IPv6 VPNs.

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

Configuring BGP VPN Services
Use to apply a route map to a VRF to modify or filter routes exported from the
VRF to the global BGP 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)#export map routemap5 filter
Use the no version to remove the route map from the VRF.
See export map.
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.
