The diagram below shows a host that has two IP addresses (n0,s,c) and (n1,s,c),
since it is connected to two subnetworks: one subnetwork is in network n0 and 
the other is in network n1. This host also has two subnetwork masks: M0 for 
network n0, and M1 for network M1. The default router R for this host is
attached to the subnetwork in network n1.

Assume that IP in this host has a packet that needs to be sent to an ultimate
destination (n',s',c'). Which of the two subnetworks does IP forward the 
packet to, and what should the hop destination for this packet be.

Solution:

If M0 AND (n',s',c') = M0 AND (n0,s,c)
   send to sub0
else if M1 AND (n',s',c') = M1 AND (n1,s,c)
   send to sub1
else
   send to R
endif
