When configuring the route-target extended community, note the following information:
• import—Imports routing information from the target VPN extended community.
• export—Exports routing information to the target VPN extended community.
• both—Imports and exports.
• route_target_ext_community—Adds the 48-bit route-target extended community to the VRF. Enter
the number in one of the following formats:

16-bit AS number:your 32-bit number (101:3)

This example shows how to configure 55:1111 as the import and export route-target extended
community and verify the configuration:
Router(config-vrf)# route-target both 55:1111
Router(config-vrf)# do show ip vrf detail
