"The main reason we are looking at the OSR is because the OSR can serve as a high-speed ingress point to the MPLS backbone that we are about to deploy," says one service provider customer. "The OSR interfaces have deeper interface buffers than the plain [Catalyst] 6509. The OSR will serve as high-density aggregation for DS-3 to OC-192."
Cisco is not yet supporting MPLS on the 7600, however -- a shortcoming noted by analysts.
"The lack of MPLS support in the 7600 was surprising, particularly given Cisco's key role in leading that charge," market tracker Current Analysis stated in a recent report. "Cisco has let a Tier 3 competitor -- i.e., Riverstone -- beat the company on the MPLS it has worked so diligently on. Riverstone should exploit Cisco's failure to support MPLS on this platform and use that as a point of differentiation."
The basic 7600 OSR system is list priced at $73,000. The entry-level system, with interfaces, starts at $100,000. The interfaces cost between $27,000 to $180,000. The 7600 OSR is available now.
Cisco says it is offering "attractive" incentives for 7500 users to upgrade to the 7600. With today's introduction of the 7600, and the recent introductions of the 10000 ESR and FlexWAN module for the Catalyst 6500, the 7500 is being squeezed out of enterprise and service provider edge applications.
Cisco says it has no immediate plans to retire the 7500, which enjoys a huge installed base.
