VxLAN tunnel local and remote tunnel IP address change is not supported.
The user must delete and recreate the VxLAN tunnel in order to change the tunnel local and/or remote address. Tunnel deletion also requires removing references to the tunnel, for example the tunnel self IP address and routes pointing to the tunnel, before the tunnel can be deleted. Those self IP addresses and routes must be re-added after recreating the tunnel with changed IP address parameters. This can be error-prone, especially if the number of tunnels is extremely large.
If a user tries to change the local and/or remote tunnel IP address, the configuration handler will fail the configuration change.
Delete existing VxLAN tunnel, and add a new tunnel with the modified tunnel IP address parameters.
Modifying VxLAN tunnel IP addresses now works. Only tunnels that have been created with a multicast flooding type and have a multicast remote IP address are supported.
