Cisco IOS XR Release 5.3.1 for Cisco Carrier 
Routing System 

PB734534 

Product Overview 

The Cisco Carrier Routing System (CRS) offers an industry-leading IP/MPLS solution delivering 6.4 Tbps in a 

single chassis and scalable to back-to-back and multichassis system configurations delivering up to 57.6 Tbps. The 

Cisco CRS delivers 

one of the industry’s highest 100 Gigabit Ethernet port densities. The Cisco CRS has delivered 

10x capacity increment over a decade on an existing footprint, providing unprecedented investment protection and 

carrier class reliability. The Cisco CRS is powered by the Cisco

®

 nPower

™

 integrated network processor which 

delivers new levels of performance and bandwidth, programmable control using open APIs and advanced compute 

capabilities; thus enabling service agility and simplified network operation for our customers. 

New Hardware Features 

The Cisco Carrier Routing System is introducing support for CRS-X 8-Slot Back-to-Back system with Cisco IOS XR 

Software Release 5.3.1. This CRS-X 8 slot chassis is capable of delivering 3.2 Tbps per system. The 8-slot Back-

to-Back capability enables service providers to double the system density to 6.4 Tbps, while preserving their 

existing investment in the CRS, with zero service disruption. Two 8-slot chassis are connected using a set of back-

to-back cables. Migration from a single 8-slot to a B2B can be done seamlessly and in service. Any CRS-1, CRS-3 

or a CRS-X single chassis or a CRS-3 Back-to-Back System can be upgraded to a CRS-X Back-to-Back System. 

The Carrier Routing System is also introducing another flavor of CRS-X linecard: FP200-Lite. The FP200-Lite card 

is a hardware optimized version of the FP-400 Card wherein one slice of 200G route processing hardware 

(nPower) is de-popped, making it more thermally efficient as well as right-priced. The FP200-Lite comes with the 

same Software capability as the FP-400 linecard, with absolutely no compromise on features or performance. The 

FP200-Lite works with Cisco IOS XR Release 5.1.4 and with Cisco IOS XR Release 5.3.1. 

The new FP200G-Lite Card has been specially designed for the Legacy Chassis Systems around three principal 

benefits: 

● 

Cost - 30% lesser than the existing CRS-X pricing (FP200 license) 

● 

Bandwidth - Linerate 200G BW available (2x100 GE/20x10GE/5x40GE) 

● 

Thermal and Power Efficiency - 10% more power efficient than the existing FP140G Card 

The Cisco IOS XR Software Release 5.3.1 also introduces new CPAK based 100G ER4 Lite optics for the 

4x100GE card on the Cisco CRS.
