Product Review

The Cisco N55-D160L3 offers a commendable capacity for IPv4 Longest Prefix Match Routes at 8k, doubling to 16k with uRPF disabled, catering to demanding network environments. However, its limitation to 8,000 IPv4 host table entries and 4,000 IP multicast routes might restrict scalability in larger, more dynamic networks. The integration of an O2 Daughter Card with L3 ASIC ensures efficient layer 3 processing, but the capped L3 interfaces and VRFs at 1K each could be a bottleneck for extensive, multi-tenant architectures.


The Cisco N55-D160L3 is designed to meet the rigorous demands of modern network environments, offering advanced features and capabilities to support complex routing and switching tasks. This module, an O2 Daughter Card equipped with a Layer 3 (L3) Application-Specific Integrated Circuit (ASIC), is engineered for efficiency and performance, providing a seamless networking experience. One of the key features of the Cisco N55-D160L3 is its support for a substantial number of routing and forwarding entries, ensuring high-speed, reliable network performance. With the capability to handle up to 8,000 IPv4 Longest Prefix Match Routes, which can be expanded to 16,000 with unicast Reverse Path Forwarding (uRPF) disabled, it is well-suited for environments with heavy routing requirements. The device also supports an IPv4 Host Table of 8,000 entries, allowing for efficient management of network hosts. In addition to its routing capabilities, the Cisco N55-D160L3 excels in multicast routing, with support for up to 4,000 IP Multicast Routes. This feature is crucial for applications that require simultaneous data delivery to multiple destinations, enhancing the efficiency of resource utilization and reducing network load. The module's support for Layer 3 interfaces (L3 Interfaces) is another highlight, offering up to 1,000 interfaces. This allows for the segregation of different network segments, improving security and reducing broadcast domains. Furthermore, the implementation of Virtual Routing and Forwarding (VRF) technology, with support for up to 1,000 VRF instances, enables multiple routing tables to coexist within the same router, facilitating improved network path isolation and traffic segmentation. Key specifications include: -
  • IPv4 Longest Prefix Match Routes: 8k (expandable to 16k with uRPF disabled)
  • IPv4 Host Table: 8,000 entries
  • IP Multicast Routes: 4,000 entries
The Cisco N55-D160L3 is designed to seamlessly integrate into existing network infrastructures, offering compatibility with a wide range of networking equipment. Its incorporation of an L3 ASIC ensures that the module not only delivers exceptional performance but also maintains efficiency, even in high-demand scenarios. This makes it an ideal choice for organizations looking to enhance their network's routing and switching capabilities without compromising on speed or reliability. Overall, the Cisco N55-D160L3 emerges as a powerful solution for businesses and network administrators seeking to bolster their networking infrastructure. With its advanced routing features, multicast support, and scalability, it stands out as a versatile component that can adapt to the evolving demands of modern networks. Whether deployed in data centers, corporate intranets, or service provider environments, this module is poised to deliver unparalleled performance and reliability, making it a valuable addition to any networking setup.
