Please log in for more thread options 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.
