We have QNX4.25 dual server system with two redundant LANs. It is configured
and work fine with Net and Net.***. On those LANs we are going to connect
dual Linux servers. We now need a way to configure a TCP/IP to route packets
and ensure the same redundancy. Does anyone know how to do it?
The masks and IP addresses are free for change. The first LAN is 10.2.201.*
and the second is 10.2.202.*. Here are some data:
sysinit.1 (and almost the same for sysinit.2)
…
Net &
Net.ether82557 -I0 -l1 &
Net.ether82557 -I1 -l2 &
netmap -f
…
netstart.1
