I'm looking for some advice on running MPLS on the 6500 platform. I've got several 6500's with Sup 720 (PFC 3A) which I am looking to upgrade to PFC 3Bs to support MPLS. However, I'm wondering if I should upgrade the modules to DFC3's to support MPLS. I imagine that the answer might be "it depends", but thought I would reach out for advice.
Anyone have recommendations or links that might help with this decision?
