  Yes, I understand.  But I don't think the *server* has a problem,
other than the sizeof(filter) in the CVS head.

  I'll fix that.

  Ah... then it's a bug in the Juniper code.

  Ascend created these things, and the Ascend boxes support 32-byte
filters.  If Juniper has re-implemented support, they probably are
more restrictive than Ascend.

  In any case, a module could hack the attributes to have the correct
length, and do so for specific clients.
