interesting because we just had a server being relocated to a different 
switch on a differekt xe port on the mx and after clearing the arp cache 
for the specific irb interface, the host was up immediately. We are 
running 11.4R2.14 and a

show arp

actually shows the xe interface instead of the irb interfaces as one 
would expect.
