p100 has no route to the network.  It knows that bigone
is at 192.168.1.1 but it doesn't know how to reach it.

bigone has a route to the network.  It knows that p100
is at 192.168.1.2 and sends the ping to that address,
but there is no reply from p100 (because p100 has no 
route to the network).

It has a route to the network.

No route to network.

Ethernet interface looks OK

No packets received.

18 packets sent (probably your pings).

Localhost is up, but there was no route shown (above) for
bigone.  That seems unusual to me, but it probably has 
nothing to do with your ping problem.

Something funny here.  Is there a line missing?
No inet addr.  No Bcast.  No Mask.

And there's the localhost.

Your problem is on p100.  It has no route to the network.
Normally on BL2, when you ifconfig eth0, the route is 
automatically set (BL1 is different -- it needs a specific 
route command).  However, your "ifconfig -a" shows no 
addresses for eth0.  If that is correct, then you need 
to check the ifconfig statement you are using for eth0.  

How are you configuring eth0?  Precisely what insmod/
ifconfig/route commands do you use?
