[c-nsp] VRF-Lite route-target import or export

[Andrew Miehs]

I can't answer which way is better, but here is another example of how to
do it:

Short version of what is described in the video - this way keeps you only
need to update your "other" vrfs rather than the common one. Seems quite
neat to me.

Red VRF:
  RD 65000:1
  RT E/I 65000:1
  RT E 65000:101
  RT I 65000:102

Red VRF:
  RD 65000:2
  RT E/I 65000:2
  RT E 65000:101
  RT I 65000:102


Common VRF:
  RD 65000:101
  RT E 65000:102
  RT I 65000:101
