|
Datacenter provides an interface for special network-settings.
|
|
Networks in Datacenters are often based on this behaviour:
|
|
A Network has an ID like 99.
|
|
This defines the VLANs: 2099 for Layer2/3099 for Layer3.
|
|
The IPv4-Range would be 10.99.0.0/16, but container will be put static in 10.99.255.0/24.
|
|
IPv6 uses RADV, so we do not need to know the IPv6-Range => auto.
|
|
VMID can be generated by Network-ID, too: smallest unused VMID in 100*ID.
