I need urgent help on this. I have a brand new cisco 2811 with 2 FE ports. The port f0/0 is connected to the internet and the f0/1 will be connected to the switch which has 4 vlans configured on it. I have no idea how to go about doing this. Can someone please help me with the configuration on the router. My responsibility is to configure the following:
* A trunk on the router for the vlans.
* 4 sub interfaces with IP address on the router.
* Route this vlans out of the network.
Our devices are hosted in a datacentre.Now we are going to place a cisco 2811 in the datacentre which will be uplinked to the backbone switch of the upstream provider.The cisco 2811 should carry vlans from a remote NOC to the internet.It is something like this:-
Backbone switch---->(f0/0)-Cisco 2811(f0/1)--(trunk)--(Remote switch)[vlan1,vlan2,vlan3,vlan4]
Now my queries are
*On the f0/1 do I configure anything or I directly create start creating sub-interfaces with the IP Addresses?
* What kind of encapsulation do I use on the vlans?
* For this network we have a class 'C'(/24), I want to subnet them into 4 subnets.
* Do I use static routes on the router? but can someone please tell me what will be my next hop?Will it be the f0/0 or the IP address of the back bone switch.

1st thing ... NEVER connect your switch to an open internet connection unless it is a Point-to-Point dedicated connection to your NOC.
2nd thing ... Although you can do packet filtering on most layer 2 and up switches they are not designed to run as a firewall. Run your switch to a PIX and your PIX to your internet router. I say PIX because you are already using Cisco equipment and it's best to stick with them.
3rd thing ... Buy SmartNet on all of your Cisco equpiment and use Cisco TAC to get your help 24x7. They will tell you everything you need Step-by-Step.
4th thing ... It will help to take some Cisco training classes.
Not meaning to sound crass or ugly but if you are being put in charge of managing your routers and switches you need to know, at the very least, the basics of routing and switching protocols and configuration techniques.

I am sorry … I misread you question. I see you have the 2811 hooked to the internet connection.
Important question … What switch are you using?
