At least you could do that; you're probably working with 
classic platforms prior to the purchase from Brocade.

In their newer platforms (which I can't name since we're 
still lab'ing), v6 is still unsupported. So you have no 
choice but to disable v6 support for IS-IS on JUNOS, or 
disable adjacency checks on Brocade, if available.

Cheers,

Mark.
