hi everybody i have a cisco router 1910 i need create a new vlan in that router, but it display that error when i create a new subinterface.
% Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q,
or ISL vLAN.
How can i resolved that trouble?
(that scenario is for a interfaz WAN)

Have you configured the encapsulation *before* the IP address?
interface GigabitEthernet0/0.901 encapsulation dot1Q 901 ip address 192.0.2.10 255.255.255.240
