Hi, As far as I know, OpenFlow doesn't seem to support such feature. To modify some header fields, OpenFlow provide the SET-FIELD action, but this action can modify the fields definited as the match fields. So if there is no corresponding field in the match fields, you can't modify the IPv4 Option fields.
OpenFlow 1.3 standard match fields: https://ryu.readthedocs.io/en/latest/ofproto_v1_3_ref.html#flow-match-structure Optionally, Nicira extended match fields: https://ryu.readthedocs.io/en/latest/nicira_ext_ref.html#module-ryu.ofproto.nicira_ext Regards, Iwase 2019年7月30日(火) 21:15 Pynbiang Hadem <[email protected]>: > Hi, > > How can I write or update the IP Option field of IPv4 header of a packet > without changing the other header fields of the packet?. > > Thanks > Hadem > _______________________________________________ > Ryu-devel mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/ryu-devel >
