Re: IP of the Router before the destination

["Phil Wang" <pywang@nortelnetworks.com>]

Hi Amirali,

In real networks, the router IP address just before the destination is
difficult to be pre-determined if the route is flexible. It's a routing
issue, and really depedens on the routing algorithms and configurations
on the device. 

However you can find the next hop towards to the destination when the
packet arrives on a particular node, by looking up its routing table (on
Linux). You're welcome to implement it.
