How to enable routing between HWIC-4ESW and Onboard FE on cisco 1841 router..?


We have a cisco 1841 router, recently i have purchased HWIC-4ESW slot for my router. The module is working fine i could able to see additional FE ports(fe0/0/0,fe0/0/1...).Now problem comes in routing i.e. these HWIC-4ESW ports and Onboard FEs are not communicating.If any bode knows the solution kindly let me know the configuration details.

Configuration steps
  1. Create your layer 2 vlans in the vlan database .
  2. Configure the corresponding layer 3 SVI on the router itself .
  3. On the 4 port hwics you cannot make them a routed port like some of the other hwics , SVI's must be used for the layer 3 definition.
router# vlan database
vlan 2
conf t
int vlan 2
ip address
