Can someone elaborate on the use of the command "rd route-distinguisher" in relation to VRF Lite? Everything I am reading seems say that you don't need to worry about this at all if using VRF Lite, it only applies when using MPLs.
I was watching the CCNP show VRF Lite part 1 & part 2 episodes and this command was entered, but I didn't really get a good feel for why or what rules to follow. Some documentation says that it doesn't really matter what you set for the route-distinguisher, as long as you are consistent. Consistent with what?
