Shimon,
the prirouter parameter is used if there is a packet routed to the osa
with an address not known in the oat. If you are using zvm 4.3+ (or
4.4+) + qdio osa and you cannot use vswitch I would use the PROXYARP
parameter in the ASSORTEDPARMS, but this works only if you have the ip
address of the system x or y in the same net of the zvm osa. You must
then define a host route to the x - ip address over the corresponding
ctc adapter of your zvm A, analog for zvm B . PROXYARP loads then all
the host routes into the oat to the correct devices and if there comes a
packet for system x it is routed to the device of zvm A.
Your config should look like this (mask class B assumed).
osa vm A 10.0.0.7
ctc vm A 10.0.1.1
ctc sysX 10.0.1.2
host route vm A 10.0.1.2 over 10.0.1.1
default route vm A as-is
default route sysX 10.0.1.1
osa vm B 10.0.0.12
ctc vm B 10.0.1.3
ctc sysY 10.0.1.4
host route vm B 10.0.1.4 over 10.0.1.3
default route vm B as-is
default route sysY 10.0.1.3
The keypoint for PROXYARP is that the ip addresses of VM A+sysX and VM
B+sysY are in the same net.

Hi,
I am not sure about something and would like confirmation.
Assuming this setup:
+-LPAR A--+-LPAR B---+
| +---+ | +---+ |
| | X | | + Y + |
| +---+ | +---+ |
| | | | |
| +----|----+ |
| | VM | VM | |
+---------+----------+
| OSA |
+-----+
VM TCPIP in LPAR A: 10.0.0.7
VM TCPIP in LPAR B: 10.0.0.12
Virtual machine X in LPAR A: 10.1.4.2
Virtual machine Y in LPAR B: 10.1.3.2
Our network routes requests for 10.1.4.2 to 10.0.0.7,
which is connected to X via a virtual CTC.
Machine X has 10.0.0.7 as its default gateway, so all
of its traffic, in and out, is via 10.0.0.7.
Now I was asked to do the same thing with a
virtual machine in LPAR B:
1) to set the default gateway in machine Y to 10.0.0.12
2) to connect VM TCPIP to machine Y with a VCTC
3) to have the network route traffic for 10.1.3.2 to 10.0.0.12
so that VM's TCPIP at 10.0.0.12 will send it on to 10.1.3.2.
My problem is that I *think* I understand that the OSA
will not agree to do this, since the VM host on LPAR A
has the OSA defined as PRIROUTER and on LPAR B
it is defined as NONROUTER.
So, my questions here are:
1) Can the task requested be done, or will NONROUTER prevent
VM in LPAR B from getting the packets for 10.1.3.2?
2) If #1 is in fact a problem, how can it be solved WITHOUT going
to VSWITCH? Is there such a solution?
Thanks,
Shimon
