Configuration of VLAN IP Addresses
When using IEEE 802.1Q VLANs these are isolated from each other and cannot reach
especially the system IP address. Therefore a so-called VLAN interface with one IP address can
set up VLANs under which this device is reachable in this VLAN (up to 16 VLANs).
For each VLAN interface an IP address and a subnet mask and optionally a gateway IP address
can be set. When setting the IP addresses take care that the ranges of the VLAN IP addresses
are not in the same subnet as the other IP addresses of the same device.
To migrate an existing system IP address to a specified VLAN use the command <set system
vlan {1-4094}>. The system IP address and the system gateway are deactivated and the
formerly set IP address and gateway for the specified VLAN interface are activated. The other
way round, the configuration of an individual VLAN interface can be adopted as system IP
address and gateway with the command <set system vlan none>.

Configuration of Unnumbered Interfaces
Unnumbered interfaces are used for IP routing to avoid to equip a point-to-point connection
with an individual IP subnet but to re-use the IP address of another (local) IP interface. This
can drastically reduce the number of configured IP sections.
The two IP addresses of the WAN/point-to-point connection are not in the same subnet.
