Conformément à la section 7.2.3.6 Spécifications du champ de correspondance de flux, section 1.3.5 (Spécifications du commutateur OpenFlow version 1.3.5 (version de protocole 0x04), section 7.2.3.8 Champs de correspondance d'en-tête, le flux permettant de modifier l'adresse IP ( dst_ip ou src_ip ) doit:

1. définir ethernet-destination-mask sur ff:ff:ff:ff:ff:ff
2. définir ethernet-type à 0x0800 .
3. définir le masque de ipv4 à 255.255.255.255 ou ip_addr/32
