route question

[Paul_Melson@keykertusa.com]

I'm having problems with `route` on my secondary (internal) interface. The 
internal interface's IP address is 10.0.1.155 with a broadcast address of 
10.0.255.255.  The default gateway is on the other interface.  I'm trying 
to construct a static route to another internal subnet (10.20.0.0/16) 
using the following commands:

route add -net 10.0.0.0 netmask 255.255.0.0 dev eth1
route add -net 10.20.0.0 netmask 255.255.0.0 10.0.11.2

10.0.11.2 is the address of the gateway router with a path to 
10.20.0.0/16, and it works for everything else on the 10.0.0.0/16 network. 
 When I issue the 2nd command, I get "SIOCADDRT: No such device" and the 
route doesn't work.  From my experience with pppd, I know that `route` is 
specifying a non-existent interface when it gives that error message. 
However, the interface is up and communicating with addresses within its 
broadcast range.  Any clues?
