<div style="font-family: Consolas; font-size: medium;">Hello,</div>
<div style="font-family: Consolas; font-size: medium;"><br>
</div>
<div style="font-family: Consolas; font-size: medium;">Can you tell me exactly how to change the br-tun and br-int in its config file?</div>
<div style="font-family: Consolas; font-size: medium;">Which file and where?</div>
<div style="font-family: Consolas; font-size: medium;"><br>
</div>
<div style="font-family: Consolas; font-size: medium;">I’m using OVS which by default also has the Linux bridge. How to take care of it?</div>
<div style="font-family: Consolas; font-size: medium;"><br>

<div style="font-family: Consolas; font-size: medium;">Thanks,</div>

<div>Hello all is there any way we can change MTU of all relevant</div>
<div>interfaces of instances,if i set</div>
<div>dhcp-option-force=26,1400 will it change MTU of all relevant</div>
<div>interfaces like qbr qvo br-int etc etc</div>
<div>is there any way to change MTU of all neutron interfaces.</div>

<div>Hello,</div>
<div><br>
</div>
<div>There is an option "network_device_mtu" on nova.conf. When tap,qvo,qbr bridges</div>
<div>are setup, it will use this setting to set MTU. However, from my experience,</div>
<div>there is no setting to set br-tun, br-int MTU setting.</div>
<div><br>
</div>
<div>I need to note that DHCP option will only cause MTU setting inside VMs.</div>
<div><br>
</div>
<div>You can follow the bug report about setting MTUs on br-int, br-tun interfaces.</div>
