Integrated Switch and VLAN on 871 routers

I am trying to set up an 871 router (1 FE WAN port, 4 FE LAN ports as an integrated switch) for a small business with classic internal, perimeter back rail, and perimeter front rail networks. Each of these networks is currently set up on a segregated, unmanaged switch. I'd like to use the VLAN function to segregate traffic from each of these switches through the LAN FE ports with ACL's to control the traffic as it comes together in the router part of the 871. Can anyone point me to sample of the statements required to set up this config? I know one thing is that I'll need the get the Advanced IP feature set to allow me to create more than the single administrative VLAN1. Also, how do you set up the trunking and subinterfaces. Is that done on a BVI interface?

Thanks in advance for any assistance.

Re: Integrated Switch and VLAN on 871 routers

Hi,

I presume that you are familiar with how to create VLANs on that platform.

Once you have created the VLANs, you can assign the ports to VLANs as follows:

interface fastethernet0

switchport access vlan 2

!

interface fastethernet1

switchport access vlan 3

!

interface fastethernet2

switchport access vlan 3

!

Then, you can create SVIs (Similar to BVIs) to enable inter-vlan routing as follows:

interface vlan2

ip address ....

!

interface vlan3

ip address...

Hope that helps - pls rate the post if it does.

Thanks Paresh. I'm waiting on the upgrade to the Advanced IP Services which will let me set up the additional VLANs, but this looks like it will do the trick for me.
