features:
|
||
|
- By default, the DHCP agent provides a network MTU value to instances using
|
||
|
the corresponding DHCP option if core plugin calculates the value. For ML2
|
||
|
plugin, calculation mechanism is enabled by setting [ml2] path_mtu option
|
||
|
to a value greater than zero.
|
||
|
upgrade:
|
||
|
- To disable, use [DEFAULT] advertise_mtu = False.
|
||
|
other:
|
||
|
- For overlay networks managed by ML2 core plugin, the calculation algorithm
|
||
|
subtracts the overlay protocol overhead from the value of [ml2] path_mtu.
|
||
|
The DHCP agent provides the resulting (smaller) MTU to instances using
|
||
|
overlay networks.
|
||
|
- The [DEFAULT] advertise_mtu option must contain a consistent value on all
|
||
|
hosts running the DHCP agent.
|
||
|
- Typical networks can use [ml2] path_mtu = 1500.
