The Cisco ASR 9901 Router is a compact yet powerful Provider Edge (PE) router, part of the Cisco ASR 9000 Series. Let’s explore its key features:

1. High Capacity: The ASR 9901 delivers an impressive 456 Gbps of nonblocking, full-duplex fabric capacity in a Two-Rack-Unit (2RU) form factor .
2. Integrated Ports:
   • 16x 1 Gigabit Ethernet (1G) ports
   • 24x Dual-Rate 1/10 Gigabit Ethernet (1/10G) ports
   • 2x 100 Gigabit Ethernet (100G) ports
3. Versatility: You can mix and match various interface types (1G, 10G, 40G, and 100G) across the ASR 9901 chassis .
4. Cisco IOS XR Software: It runs on the same Cisco IOS XR software image as other routers in the ASR 9000 Series, allowing standardization on the same operating system .
5. Applications:
   • Layer 2 and Layer 3 aggregation
   • Data Center Interconnect (DCI)
   • Satellite Network Virtualization (nV) System mode
6. MAC-SEC Encryption: The ASR 9901 supports industry-leading MAC-SEC encryption on all its port speeds .

This router sets a new standard for service density and scalability, making it ideal for large-scale aggregation and carrier Ethernet transport networks. Its versatile capabilities reduce both capital and operating expenses, while the Cisco IOS XR 64-bit operating system ensures reliability and high availability .
