Cisco 106 - Configure native VLAN on a router

Two methods to configure native VLAN on a router:

1)Set the VLAN ID on a sububinterface:
(config)#int g0/0.10
(config-subif)#encapsulation dot1q 10 native

2)Config the IP address for the native VLAN on the router's physical interface. The encapsulation dot1q command is not necessary with this option.
First remove the subinterface:
(config)#no interface g0/0.10
Then configure the IP address of the physical interface:
(config)#interface g0/0
(config-if)#ip address 192.168.1.62 255.255.255.192

Here is the running config of a router with the physical interface using the native VLAN and two sub-interfaces configured for other VLANs:

!
interface GigEthernet0/0
 ip address 192.168.1.62 255.255.255.192
!
interface GigEthernet0/0.20
 encapsulation dot1Q 20
 ip address 192.168.1.126 255.255.255.192
!
interface GigEthernet0/0.30
 encapsulation dot1Q 30
 ip address 192.168.1.190 255.255.255.192
!
