qrouter but it doesn't working.<br>
<br>
default MTU setting on neutron router interface is 1450 MTU  i want to<br>
change to 1500<br>
<br>
[root@controller neutron(keystone_admin)]# ip netns exec<br>
qrouter-b17c9641-27f7-4328-<wbr>82b0-c3132cccdcf1 ifconfig | grep mtu<br>
...<br>
qr-edb341ca-ac: flags=4163<UP,BROADCAST,<wbr>RUNNING,MULTICAST>  mtu 1450<br>
<br>
<br>
I have changed following file<br>
<br>
neutron.conf   ->  global_physnet_mtu = 1550<br>
ml2_conf.ini    ->  path_mtu = 1550<br>
<br>
and restarted following services<br>
<br>
systemctl restart neutron-openvswitch-agent<br>
systemctl restart neutron-l3-agent.service<br>
systemctl restart neutron-server.service<br>
<br>
<br>
Now i am creating new router and attaching subnet but still its using<br>
1450 MTU what is the solution for it? do i need to reboot BOX??<br>
