Unfortunately Solaris 10 on these machines isn't an option for us at
this point (vendor support for services, etc). Also the Sun Trunking
product (the only Solaris 9 solution I found) doesn't support all of our
hardware (V240s, V440s & V1280s with bge, ce & qfe interfaces and
inter-interface-family pairs) :\

IPMP was configured by Sun Professional Services, it provides our
required level of resilience, and like it or not I have to live with it.
I won't debate that Channel Bonding would be a better solution
(particularly with Solaris 10), but I don't believe it's an option.

So, back to my original question: should the pfil ipmp interface be able
to do this, and if not, why not? Surely it just provides a logical name
pointing to the "active" member of the ipmp group?! If this is the case,
I don't see any reason for it not to work with fastroute.

Best regards,
Robin
