routing table madness

[Lonni J Friedman]

I've got an entry in the routing table that conflicts with another
entry that I use to connect to my employer's VPN (using vpnc).  I'd
like to delete the route, but no matter what I do, it doesn't work.
First, here's 'route -n' output:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
172.16.217.26   0.0.0.0         255.255.255.255 UH    0      0        0 tun0
216.228.112.12  10.0.2.2        255.255.255.255 UGH   0      0        0 eth0
172.16.229.26   0.0.0.0         255.255.255.255 UH    0      0        0 tun0
10.0.2.0        0.0.0.0         255.255.255.0   U     0      0        0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U     1002   0        0 eth0
172.16.0.0      0.0.0.0         255.240.0.0     U     0      0        0 tun0
10.0.0.0        0.0.0.0         255.0.0.0       U     0      0        0 tun0
0.0.0.0         10.0.2.2        0.0.0.0         UG    0      0        0 eth0

The route that I'd like to delete from above is:
10.0.0.0        0.0.0.0         255.0.0.0       U     0      0        0 tun0

Unfortunately, when I attempt to delete the '10.0.0.0 tun0' route, it
fails to work:
# route del 10.0.0.0
SIOCDELRT: No such process

Similarly:
# ip route del 10.0.0.0
RTNETLINK answers: No such process


Surely I'm doing something wrong here, but I can't figure out what
after googling for a while.
