ieMentor CCIE™ Service Provider Workbook v1.0 | Lab15 Solutions: Advanced MPLS I Task 15.1: ♦ Configure VPN Green site 1 such as to prevent communication to site 2. ♦ Configure VPN Green site 1 to talk to site 3. This task requires you to reconfigure VPNs to split in to multiple VPNs by using different RDs, which will allow you to control routes from one site to another.

Otherwise, you won’t be able to communicate with the two VPNs. You can import/export on greensite3, or you can use export 1:1 on green-site3 and export 3:3 on green-site1, or import/export on PE4. The solutions will work in both cases.

This task has a few problems. When you summarize 8.0.0.0/8, make sure don’t forget the 8.1.1.0/24 routes coming from BB1. You would need to exclude this from the aggregate list so there is no conflict of a summary.
