Hi,
My last message was premature. The problem is not the packet size.
It is in the routing code.
I need to get the routing code working correctly for our network.
Since it is segmented by L1 routes
What I need to do is have the endnode populate its neighbors from the hello
messages.
If the destination is not on the local segment, send the packet to the L1
Router
Or if the packets source is the L1 Router send the reply to the L1 router
and not the destination.
Below is the tcpdump of a ping from 1.43(VMS) to 1.99(linux)
from linux.
1.99 is on a segment by itself with the router 1.405
1.43 is on a different segment with router 1.405
