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 433 for

information about global export maps and IPv6 VPNs.

global 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.

• 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).

import map

• 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.
