I have finished implementing this step by step, and things still do not 
appear to be working.

During the testing phase, I have two problems (output which differs from 
what the howto says I should get).
1) When I run "ip route list table main", only the proper entries for 
NWE1/NME1 and NWE2/NME2 come up, not the one for NWI/NMI.
2) "ip route get from (IPE1|IPE2) to 204.152.189.113" both return 
"network unreachable"
All the other output matches exactly.

My only thoughts are that I've swapped an IP or two somewhere, but I've 
been over the script a ton of times already, and nothing presents itself 
to me.

Any help or troubleshooting hints would be greatly appreciated.
