What is the benefit for a company to use an ISR router?
- An ISR provides the functionality of a switch, router, and firewall in one device.
- ISRs use a PC operating system for routing traffic, thus simplifying configuration and management.
- An ISR is immune to security attacks by hackers and so replaces all other network security measures.
- ISRs make routing decisions at OSI Layer 7, thus providing more intelligence to the network than do other routers.
