In this paper, the reader follows along as a set of software routers are migrated to Cisco hardware routers. Software routers, while easy to setup and maintain, suffer from a number of performance and security issues:
- Non-purpose-built solution results in additional CPU processing and lower overall bandwidth
- Security patches are not specifically tailed to routing infrastructure needs
- Monitoring and management functions are – at best – substandard compared to dedicated hardware solution
This paper begins by outlining the current state within a small â€“ but quite real and used â€“ lab. The lab moreover is hardened to military standards and provides services to a number of consumers, but was initially constructed entirely with software routers. As dedicated hardware become available, this state of affairs required a change; namely, migrate the software routers to their dedicated hardware equivalent. Follow along to see how this was performed within a minimal impact on the labâ€™s overall availability (not to mention confidentiality and integrity!).
