Hi, SIP-600 has only one non-overbooking 10GE interface. ES-20 line cards are 2 times SIP-600. Besides QoS features that you all mentioned MPLS/VPLS is done on WAN cards (as uplink ports). As an access port you can do many VLAN tag manipulations (rewrites, addes, etc), termination of q-in-q traffic on ES-20 line cards.

These ports will be used for backbone links between other 7600 chassis in a MPLS cloud supporting a triple-play offering that will ultimately include HD video, VoD, VoIP, and high-speed data over FTTx. These ports would not be customer-facing. I'm looking at the new S chassis to complement our existing 7613s. I'm aware of the 10G SPA option but my understanding is that I can only get wire speed out of 2 10G SPA ports on a SIP-600 because it only has a single 20G backplane connection. The ES20 would be nice if only it was more dense. $80k for 2 ports before optics is not terribly feasible. The $40k Advanced IP license for the ES20 is also both surprising and painful. The ES40 would be an option if it comes in at the price of the ES20 (or less) but my understanding is that it is more than a year out. The only option I see is the 6704 (6708 would be alright until we actually near the 40G backplane limit). The Dynamic Config Tool also claims that none of the 6708 models are compatible with SRB but the 6704 is supported. Is this another side-effect of the BU split? I'm looking at a PPT of the differences between the ES20, SIP-600, and 67xx linecards. It points to differences in queues (1/2RX, 4/8 TX); shaping, HQoS, LLQ (use strict priority), VPLS uplink, VPLS with MPLS edge, and local VLAN significance are all not supported. It also points out a difference in the scheduler for the ports. Nothing in this list jumps out at me as something I'll need for this particular deployment of P routers. The price difference is very significant as well. So, that said, can anyone think of any reasons why we shouldn't go with the 6704/8 over the ES20, at least until the ES40 comes out? What else am I missing?
