Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

eth0 is the default gateway for the box
eth1 has a gateway for the local LAN, 192.168.1.1
The LAN has several VLANs, 192.168.105.0 for instance.
192.168.1.1 is the default gateway for the entire LAN. This is a switch with routing enabled, and it's also 192.168.105.1, etc.
From the problem box, traceroute 192.168.105.x shows that that traffic heads out eth0 despite all my efforts, i.e. static routes; i have modified sysconfig/network-scripts/route-eth1 as here:
192.168.105.0 via 192.168.1.1
192.168.105.0 via 1.247
it is critical that I be able to interact with this box to/from my other VLANS. I'm stumped.
