Description Andrey Mazo 2009-12-22 09:20:02 UTC

CreateTap () method tries to get IP address and Mac address from underlying NetDevice.
If IP address is not assigned to the underlying NetDevice, CreateTap () will die even if that IP address is not really required (not in CONFIGURE_LOCAL mode).

Currently it is possible to create a tap bridge only for an interface with an IP address.

Although it's always possible to assign address to all interfaces, it may be rather difficult to introduce additional stub IP subnets in complex topologies.
