[Olsr-users] OLSR v1, v2, and virtual interfaces

VLAN interfaces. We have found that the only way to get OLSRv1 to work at
all is to give it its own interface. This makes single-port devices meshing
over the Ethernet interface impossible.

As Meta Mesh explores new ways of building the PittMesh network we're
looking for improvements and this would be a big one. We'd love to stick
with OLSR for awhile but is there a way to make this work?
