It makes sense to me -- there's nothing on the physical interface, so IPMP
migrates the address back there rather than to a logical. The workaround
would be to set a 0.0.0.0 -failover address on the physical interface.
Address migration is a major wart in the IPMP design, and something that
Clearview is in the process of disposing of.
