The RSP16 supports up to 1 GB of program memory, allowing customers to significantly increase their route tables. The RSP16 provides significant performance enhancements, increasing switching performance by 20 percent and 55 percent compared the RSP8 and RSP4+, respectively.
The RSP16 is available as an upgrade to an existing RSP and supports the VIP2, VIP4, and new VIP6-80.The RSP16 does not support legacy interface processors, except for the CIP2, GEIP, GEIP+, FEIP2-DSW-2TX, FEIP2-DSW-2FX, SRPIP, CX-CIP2-ECA1 and ECA2.
