Peter, I resolved this. I came across a reference to a package available with Ubuntu called ifupdown-extras. It adds a file in /etc/network/ called routes. http://askubuntu.com/questions/168033/how-to-set-static-routes- in-ubuntu-server
I added the package and edited my /etc/network/interfaces to remove the post-up route statements and added them into the /etc/network/routes file as; ## Network for A 10.101.0.0 255.255.240.0 10.100.1.254 eth1 10.100.1.0 255.255.255.248 10.100.1.254 eth1 ## Network for B 10.100.1.24 255.255.255.248 10.100.1.254 eth1 10.114.0.0 255.255.248.0 10.100.1.254 eth1 ## Network for C 10.100.1.16 255.255.255.248 10.100.1.254 eth1 10.113.0.0 255.255.248.0 10.100.1.254 eth1 ## Network for D 10.112.0.0 255.255.240.0 10.100.1.254 eth1 After multiple reboots the routes seem to be working each time.

I had a typo in one of the statements and because the gateway was not seen as a local interface, it did not add that route. I'm not sure if this is a workaround or the intended function on Ubuntu's part based on the ifupdown-extra being available. Thought I'd pass it along.
