ostinato.protocols.gre_pb2 module

Configure GRE protocol attributes to encapsulate and tunnel network traffic within Ostinato streams using the GRE object

To add and configure Gre in a stream, add a protocol to the stream, set the protocol id to ost_pb.Protocol.kGreFieldNumber and access the Gre object from the Protocol object's Extensions dictionary using the key gre_pb2.gre

from ostinato.protocols import gre_pb2
...
# stream is an object of type ost_pb.Stream
proto = stream.protocol.add()
proto.protocol_id.id = ost_pb.Protocol.kGreFieldNumber
my_gre = proto.Extensions[gre_pb2.gre]

You can then set Gre attributes using my_gre.<attribute>
