They are a different feature. In short VRFs are separate routing tables
to provide routing isolation. They are somewhat different with respect
to namespaces as the isolation is visible to userspace.

In the meantime I was able to find a workaround by setting the sysctl
variable:

net.ipv4.udp_l3mdev_accept=1

this way the socket that is created in the default VRF is automatically
visible in all VRFs.

A proper binding to the correct VRF would be a better approach, however.
