Hi,
We have tried the following to try and get the Linux LPAR to talk to the
rest of the network :
The ip details we used is :
147.110.49.16 - 4host subnet
255.255.255.252 - network mask
147.110.49.17 - host address for the TR0 interface on the Linux LPAR
147.110.49.18 - interface address on the 2216 router that provides
connectivity into the mainframe.
ifconfig tr0 147.110.49.17 netmask 255.255.255.252 broadcast
147.110.49.19
route add default gw 147.110.49.18 netmask 0.0.0.0 metric 0
This is what happens :
The route 49.16 appears on the 2216 routing table and shows that it is
directly connected to the Linux LPAR via the interface on the 2216.
We can then ping 49.17 from the 2216 and 49.18 from the Linux LPAR.
However we cannot get connectivity to the rest of our network.
I think that there needs to be some sort of routing protocol on the
Linux LPAR for this to work.Is there anything else that can be loaded
for this to be effective?
Thanks
