Hello,
Dear
I checked the previous same thread "dec_ttl not working", however, there was no
clear answer for me.
I need your help in this
I am using mininet v 2.0 and OVS 1,10
I run wireshatk in the background to check the IP-TTL value, however it isn't
decremented
I have used the following commands in riplpox to decrement the IP_TTL in
reactive mode
def install(self, port, packet, buf = None, idle_timeout = 0, hard_timeout =
0,
priority = of.OFP_DEFAULT_PRIORITY):
# msg = of.ofp_flow_mod()
msg = nx.nx_flow_mod()
# msg.match = match
msg.match.eth_src = packet.src
msg.match.eth_dst = packet.dst
msg.idle_timeout = idle_timeout
msg.hard_timeout = hard_timeout
msg.priority = priority
msg.actions.append(nx.nx_action_dec_ttl())
msg.actions.append(of.ofp_action_output(port = port))
msg.buffer_id = buf
self.connection.send(msg)
