RE: Virtual Ethernet

["Ingvaldson, Scott" <scott.ingvaldson@xxxxxxxxxx>]

I'm "assuming" that's what is happening, but I'm not sure exacly how to
prove it, short of a trace and I'm thinking that this should not be that
hard to solve.  I can ping the 192.168 addresses from either LPAR but
not from any network attached workstations (which is what I would
expect.)  I set up host table entries to point to the 198.162 addresses
and tried to set up a route to force the outgoing traffic to the virtual
ethernet line, but could not due to msgTCP264F - SUBNETMASK parameter
value not valid, RC0006 - The route does not have a subnet mask that
masks the corresponding one bits in the host portion of the route
destination.                          

The LPAR IP addresses are configured as 192.168.10.xxx and I have tried
subnet masks of 255.255.255.0, 255.255.0.0 and 255.255.254.0.

Any chance it is routing the long way around?  I don't know how your
network is configured but I had one customer that was using the
"external" ports rather than the V-lan.  I think we added some routing
entries but I don't exactly remember.  Use traceroute to see if the
route is OK?
