SUMMARY: Network/IPMP configuration difficulties

Thanks for the responses from Pascal G, Don R, John H, Matthew T, and Glenn P.

Pascal was the first onto my main problem - the files really are 
called "hostname.e1000g0", and not <hostname>.<device name> as I originally 
interpreted.  Seems like I was thinking too much :-/

The mail that really got me up and running came from Glenn P.  He provided 
configuration suggestions for the interfaces, which I used.  One reboot 
later, the interfaces were up and configured as I wanted them.  

I then quickly discovered that the ipfilter was also in the way, configured to 
block everything execpt traffic on e1000g2, but that was a minor detail at 
the end.

The files I have in the end are:
/etc/hostname.e1000g0
wallaby netmask + broadcast + group globalnet up

/etc/hostname.e1000g1
wallaby-interchange netmask + broadcast + group interchange up

/etc/hostname.e1000g2
group globalnet -failover standby up

/etc/hostname.e1000g3
group interchange -failover standby up

Also to note was that IPv6 needs to be configured on the interfaces too.  I 
did this as follows:
/etc/hostname6.e1000g0
group globalnet up

/etc/hostname6.e1000g2
-failover group globalnet up


Everything seems to be fine now.  

Thank you for the help!

best regards
Markus
