Routing on a stick configuration

Hi,

I was reading up CCNP switching guide and got this qns on configuring VLAN routing using external router and a switch.

Router A FA0/1 ---link--- Switch A FA0/1

Switch A has got a number of VLAN eg 10, 20, 30, 40

Router A has got subinterface according to VLAN number eg FA0/1.10=VLAN10, FA0/1.20=VLAN20 etc

1) The thing is i have got no idea how to configure Router A's subinterfaces to associate with the VLANs

2) The link shd be a trunk link right?

3) Switch A shd be a VTP Server or Transparent?

4) Router A shd be a VTP Server or Transparent?

how would u guys go abt configuration both devices so VLANs can route between each other...?

Thanks

Re: Routing on a stick configuration

Router doesnt participate in VTP. VTP is only between switches.

Configure The link on the switch to router as a trunk.

On Switch -configure the following

int fa0/1 ---> trunk port on switch

switchport mode trunk

switchport trunk encapsulation dot1q (or isl)

switchport trunk native vlan 1

On Router - configure the following

int fa0/1.10

encapsulation dot1q 10 (can use isl also)

ip add

int fa0/1.20

encapsulation dot1q 20 (can use isl also)

ip add

That should do it.
