What is ISR/ASR Routers?

ISR/ASR routers are Integrated Services Routers (ISR) and Aggregation Services Routers (ASR) manufactured by Cisco. ISRs are designed for branch offices and small to medium-sized businesses, offering a range of services like routing, switching, security, and WAN optimization. ASRs are typically deployed at the edge of larger enterprise networks or by service providers, focusing on high performance, scalability, and advanced services aggregation. They are commonly used to connect different network segments, provide secure connectivity, and deliver various network services like voice, video, and data.
