  The braneworld model of Dvali-Gabadadze-Porrati (DGP) provides an interesting
alternative to a positive cosmological constant by modifying gravity at large
distances. We investigate the asymptotic behavior of homogeneous and
anisotropic cosmologies on the DGP brane. It is shown that all Bianchi models
except type IX isotropize, as in general relativity, if the so called
$E_{\mu\nu}$ term satisfies some energy condition. Isotropization can proceed
slower in DGP gravity than in general relativity.
