New Developer Resources in Release 1.2.4

• VRF developer guide

• Implement “VLAN device model” instead of convoluted decision tree

• VLAN integration test cases

Bug Fixes in Release 1.2.5

• VyOS BGP configuration syntax changed local-as to system-as in release 1.4.

• Set VLAN mode on routed virtual links, not on parent interfaces

• Copy VLAN data into routed subinterfaces

• Use parent interface and subinterface data to create subinterface name (needed to get VLAN ID into subinterface name)
