And if you'd need anything other than Ethernet, the SIP-cards are there for you. If you don't need anything advanced I can't see why the 7600 isn't a good idea. I'm not sure, but AFAIK it can do QoS queuing and scheduling on MPLS EXP bits, and it supports MPLS TE, so from my point of view it'd be a "perfect" P-box. Just my €.02. :-) Regards, Peter ------------------------------------ The Cisco rationale is that is not designed to be a P-layer device and it does not support the same convergence times as a CRS-1...... Personally I feel they have concerns because we will be using a dual vendor strategy in the core with a Juniper MX480... No virus found in this outgoing message. Checked by AVG Free Edition.
