Whenever I’m explaining MPLS/VPN technology, I recommend using the same route targets (RT) and route distinguishers (RD) in all VRFs belonging to the same simple VPN. The Single RD per VPN recommendation doesn’t work well for multi-homed sites, so one might wonder whether it would be better to use a different RD in every VRF. The RD-per-VRF design also works, but results in significantly increased memory usage on PE-routers.
