when I configure multiple subinterfaces on a router ,
the system prompt:
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.

and, my desireble configurtion like this:

interface FastEthernet0/0.1
description link-vlan2
encapsulation dot1Q 1 native
ip address 172.16.26.2 255.255.255.0
ip access-group 100 in
!
interface FastEthernet0/0.2
description link-vlan3
encapsulation dot1Q 2
ip address 132.115.75.222 255.255.255.224
ip access-group 100 in


then what's the matter ,what should i do? thanks a lot.
