Cisco XR-2PK-MEM-PRP2 Memory Upgrade Kit for XR 12000 RP

The Cisco XR-2PK-MEM-PRP2 Memory Upgrade Kit for the XR 12000 RP adds a total of 4 GB of DRAM to the Performance Route Processor 2 by including two MEM-PRP2-2G modules (2 GB each). These DRAM modules are designed for the XR 12000 Series PRP-2 and are installed in the RP to expand memory capacity, enabling larger routing tables and smoother operation during IOS XR software upgrades. Cisco documentation confirms MEM-PRP2-2G as a 2 GB DRAM option and lists MEM-PRP2-4G as a 4 GB DRAM option for PRP-2 deployments, making this 2x2 GB kit a standard path for memory growth. In XR 12000 PRP-2 environments, 4 GB of RP memory is identified for heavier workloads (for example with BGP or sizeable routing tables), so this upgrade kit is appropriate when migrating from smaller memory configurations or planning for future features.
