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?
If your current modules are classic line cards, moving to DFC3 enabled line cards will dramatically increase the throughput in the switch, not just for MPLS.
Instead of me rambling about all the benefits of moving away from classic line cards to DFC3 enabled line cards, I recommend reading this comprehensive article on the 6500 architecture.
