Paper: Understanding routing in multi-homed HP-UX environments

Multi-homed HP-UX servers, especially ServiceGuard nodes, present a challenge in terms of routing, which is further exacerbated by the lack of documentation on the subject.

This paper tries to explain how to configure multi-homed servers to enhance the routing of IP packets and prevent asymmetric routing.

Note that I call this paper a "graypaper". I do not work for HP, nor do I have any internal knowledge of HP-UX. The information in this paper has been determined by looking at the output of tcpdump and by reading publicly accessible documentation and posts in the ITRC forums. This document is provided "as is" without any warranty.
