PRP-3 is the route processor for the Cisco XR 12404 and 12804 Router chassis

running Cisco IOS XR Software Release 3.8.0 or a later release. The PRP-3 is

available as product number PRP-3 or PRP-3= for a primary route processor and

is available as PRP-3/R for a redundant route processor. PRP-3 has significant

improvements over PRP-2. These improvements include increased speed,

improved scalability, higher system memory, faster packet processing. Because

PRP-3 does not support Cisco IOS, the bootflash memory no longer exists in

PRP-3. PRP-3 ROMMON has software intelligence to download a Cisco IOS XR

image without the support of bootflash memory.

PRP-3 supports Cisco XR 12416 (10 G per slot fabric) and Cisco XR 12816 (40

G per slot fabric) Router chassis only. PRP-3 does not support Cisco XR 12004,

12006, 12010, and 12016 Router chassis (2.5 G low-speed fabric).
