IS-IS issue over ethernet subinterface

Hi GS,
I am having a issue setting up IS-IS over ethernet subinterfaces.

here is my setup:

R1 (trunk) ---(trunk) SW1 (trunk) ----(trunk) SW2 (trunk) ----- (trunk) R2

R1 Configs:

int fa0/0.12
encapsulation dot1q 12
ip address 10.10.10.1 255.255.255.0
ip router isis

router isis
net 47.0001.0000.0000.0001.00

SW1 configs:

fa0/1
switchport trunk encap dot1q
switch port trunk allowed vlan 12
switch mode trunk

vlan 12 is carried across the trunk link between SW1 and SW2

R2 configs:

Int fa0/0.12
encapsulation dot1q 12
ip address 10.10.10.2 255.255.255.0
ip router isis

router isis
net 49.0001.0000.0000.0002.00

SW2 configs:
int fa0/2
switchport trunk encap dot1q
switch port trunk allowed vlan 12
switch mode trunk

Please help.

Regards
