ostinato.protocols.ip4over4_pb2 module

Create IPv4 over IPv4 Ostinato streams by adding the protocol and customizing both outer and inner IPv4 attributes efficiently

Ip4over4 is a combination of Ip4 followed by Ip4.

To add and configure Ip4over4 in a stream, add a protocol to the stream, set the protocol id to ost_pb.Protocol.kIp4over4FieldNumber and access the Ip4over4 object from the Protocol object's Extensions dictionary using the key ip4over4_pb2.ip4over4. The outer and inner Ip4 objects can then be accessed using the Ip4over4 object's Extensions dictionary using the keys ip4over4_pb2.ip4_outer and ip4over4_pb2.ip4_inner respectively.

from ostinato.protocols import ip4over4_pb2
...
# stream is an object of type ost_pb.Stream
proto = stream.protocol.add()
proto.protocol_id.id = ost_pb.Protocol.kIp4over4FieldNumber
my_ip4over4 = proto.Extensions[ip4over4_pb2.ip4over4]
my_ip4_outer = my_ip4over4.Extensions[ip4over4_pb2.ip4_outer]
my_ip4_inner = my_ip4over4.Extensions[ip4over4_pb2.ip4_inner]

You can then set outer and inner Ip4 attributes using my_ip4_outer.<attribute> and my_ip4_inner.<attribute> respectively.
