Evolving SRv6 (Segment Routing for IPv6)
Implements: 1.- SR Policies with several (weighted) SID lists 2.- Binding SID 3.- SR LocalSIDs with support for the following functions - End - End.X - End.DX6 - End.DX4 - End.DX2 - End.DT6 - End.DT2 - End.B6 - End.B6.Encaps 4.- SR Steering policies (to steer a traffic through an SR Policy) - Support for IPv6 traffic (IPv6 Encapsulation / SRH insertion) - Support for IPv4 traffic (IPv6 Encapsulation) - Support for L2 traffic (T.Insert / T.Encaps) 5.- Doxygen documentation 6.- Framework (APIs) to allow the definition of new SR LocalSID behaviors by means of plugins 7.- Sample SRv6 LocalSID plugin Change-Id: I2de3d126699d4f11f54c0f7f3b71420ea41fd389 Signed-off-by: Pablo Camarillo <pcamaril@cisco.com>
