Hello Mikhail:
"max_tunid" is a read only parameter set by OVN (Neutron can only read it). It is used to determine the capacity of the cluster depending on the tunnel types enabled for encapsulation.
This option is useful only when VXLAN is enabled, due to limitations in the protocol header. For more info, please read [1].
In a nutshell, if you allow VXLAN, then the "max_tunid" value will be reduced to 4095. If not, the value will be 16711680 (0xFF0000).
Regards.
