We are currently migrating our SP network to MPLS, and i have the following challenge. As of today, i have a lan2lan connection between two 6509 in two different regions.
I have a service-policy applied,to provide customers with a certain bandwidth across this link. The business model gives the customers the possibility to purchase for example 10Mbit access to resources in an extranet in location A, and for example 2Mbit access to resources in Location B. The problem is, we are moving this extranet into a VRF, and running tag-switching on the lan2lan between the two 6509s. Considering that there are 18000 routes in this extranet, spread across the two locations, we do not want to shape/police the traffic at the inbound access, as this will be very painful with this large amount of routes.
So, right now, i am planning on having a GRE tunnel between the two routers, and keeping the existing service-policy, but i would like to see if there is any way to shape on the MPLS link itself. The service-policy i am using today will never work once the extranet is moved into the VRF, as it will no longer see the IP packets traversing the MPLS link.
So, basically, we are looking for a method to shape traffic within a VRF before it is switched across an MPLS link.
I am also looking for a way to shape a VRF, if possible, before traversing a link.
