Network is unreachable

Question

I'm a bit lost trying to solve this one.

This is a machine coming up on Google Compute Engine.

It says "Network is unreachable" when I try to access the network.

The network appears to be functioning because eth0 has a network address which it got from the Google DHCP server. Below is the output of "ifconfig" and "route"

Google says that the network this machine is on is 10.240.0.0/16 with a gateway at 10.240.0.1

Output of route -n

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
127.0.0.1       *               255.255.255.255 UH    0      0        0 lo

Output of ifconfig -a

Answer 1

The following worked:

sleep 10 (not sure if this line matters but it seems the system needs a few seconds for something to complete?)
sudo udhcpc
sudo route add -net 10.240.0.0 netmask 255.255.0.0 dev eth0
sudo route add default gw 10.240.0.1 eth0
