I have done a little work using VRF's recently and understand to a
limited extent their purpose.
I now have a situation where I have to use a GRE tunnel across a carrier
MPLS cloud to solve a particular problem.
My questions:
When a VRF is configured, is the VRF / RD value physically 'tagged' to a
route when the route is advertised out to a neighbor using a dynamic
routing protocol?
When I configured a VRF previously I assigned my VRF value to both
routing information as well as a physical interface on my router. If a
VRF is a routing instance why was it needed on the interface?
Most importantly, if I use GRE, does the GRE header hide the route
tagging so that it is invisible as it flows over the carrier network ?
NB My tunnel interface will be assigned with the VRF value.
