We've talked about this before I want to inquire about it again. When would one use the ES20 over the 6704/8? My understanding is that the ES line is a more dense substitute for advanced SPA ports. These advanced features are useful for customer-facing interfaces. Would that be a fair assessment?
I'm running MPLS across my existing 7600 core. I'm adding 3 7609 chassis as a distribution layer. 10G is needed to support our FTTx roll-out among other things. I'm looking at 6704/8s for chassis to chassis connections and ES20s (soon to be ES40s) for customer-facing GigE or 10G interfaces if we plan on using MPLS capabilities for those customers. We're running MPLS across our core now and will extend it to encompass the distribution layer as well. We'll be carrying mcast across the network for IPTV, though I'm not sure if we'll be utilizing mvpn at this time. MPLS-TE w/ FRR & BFD will be implemented as well. IS-IS is the IGP. We have to run the SR train for CALEA support. Does any of that make one lean towards the ES series over the 67xx series blades in either the backbone connections or the customer-facing connections? The price difference is the biggest con at this point unless there's a technical reason to choose one over the other.
