1 C H A P T E R Migrating to a Cisco CRS-3 Carrier Routing System This chapter describes how to migrate a single-chassis Cisco CRS-1 Carrier Routing System to a single-chassis Cisco CRS-3 Carrier Routing System. Note For an introduction to the single-chassis Cisco CRS-3 Carrier Routing System, see Cisco CRS Carrier Routing System 16-Slot Line Card Chassis System Description. For information on planning a single-chassis Cisco CRS-3 Carrier Routing System system installation, see Cisco CRS Carrier Routing System 16-Slot Line Card Chassis Site Planning Guide. Feature History for the Cisco CRS-3 Carrier Routing System Release Release 4.0.0.T Release 4.0.1 Release 4.0.2 Modification The single-chassis Cisco CRS-3 Carrier Routing System was introduced. The single-chassis Cisco CRS-3 Carrier Routing System adds support for 100GE interfaces. Multishelf Cisco CRS-3 Carrier Routing System operation is supported and multishelf Cisco CRS-1 Carrier Routing System to multishelf Cisco CRS-3 Carrier Routing System migration is supported.
