  The H2 and optical (Ha, [NII]) morphology of NGC 6881 are very different.
Here we present a preliminary report of the analysis of new optical (Ha and
[NII]) and near-IR (Brg and H2) images and intermediate resolution JHK spectra
of this nebula. Our observations confirm the association of the H2 bipolar
lobes to NGC 6881 and reveal that H2 is predominantly shock excited in this
nebula. We conclude that NGC 6881 has multiple bipolar lobes that formed at
different phases of the nebular evolution and that the collimation conditions
or even the collimating agent changed from one ejection to the other.
