If you turn on gateway HA, the traffic should move to another host.

There is no expiration of MAC_Binding entries.  This needs to be improved.

[ovs-discuss] [ovn] Chassis Table or MAC_Binding Table in ovn-sb have aging?

[Guoshuai Li]

Hi All


When the chassis node power off, the south of the database to the 
Chassis table also exists.


For example, the gateway node power off, but the chassis information 
still exists, the traffic continues to forward the package to the chassis.



When an external IP address is destroyed, MAC_Binding also has this IP.

For example, the MAC address of the device of the external gateway 
changes (changed one). If there is no external ARP packet, MAC_Binding 
will not be updated.



Is there a good way to solve this problem?

please help

Thanks
