A Cisco router is a network device designed to pass data between different networks and is a key component in building the Internet infrastructure. It transmits packets from a source network to a destination network by looking at the destination address and determining the best path based on a routing table.
Cisco routers support a wide range of network protocols, including IP, IPv6, OSPF, BGP, and more, and can provide robust security, flexibility, and reliability features. The Cisco router product line includes several series and models covering users of different sizes and needs, providing reliable network connectivity and advanced network management capabilities for different users.
