export map examples

Usage Guidelines

The export map command is used to associate a route map with the specified VRF. The export map is used to filter routes that are eligible for export out of a VRF, based on the route target extended community attributes of the route. Only one export route map can be configured for a VRF.

An export route map can be used when an application requires finer control over the routes that are exported out of a VRF than the control that is provided by import and export extended communities configured for the importing and exporting VRFs.

Examples

In the following example, an export is configured under the VRF and an access list and route map are configured to specify which prefixes are exported:

Router(config)# ip vrf RED 

Router(config-vrf)# rd 1:1 

Router(config-vrf)# export map BLUE 

Router(config-vrf)# route-target import 2:1 

Router(config-vrf)# exit 

Router(config)# access-list 1 permit 192.168.0.0 0.0.255.255

Router(config)# route-map BLUE permit 10 

Router(config-route-map)# match ip address 1 

Router(config-route-map)# set extcommunity rt 2:1 

Router(config-route-map)# end
