Which Cisco 1921 router modules are best ?

[miank]

I have PPPoE internet connection from my ISP and its terminating on (Optical Network Terminal) device. I want to connect RJ45 from my ONT to Cisco 1921 router, so that i can use my router as PPPoE dialer and as well as giving internet to other users in my network. I can use normal Linksys router with WAN port, BUT I want to use CISCO 1921/K9.

Kindly can anyone tell me that which modules i have to have with CISCO 1921/K9 ?

and sholud i need to have four port 10/100 ethernet module ???

thanks.

Before we continue further, what is the bandwidth of your ISP?

@ leolaohoo

Thanks for reply , for now its 2MB but in future it may go upto 10MB

Thanks

The 1921 has two GigabitEthernet ports.  One for your WAN, one for your LAN.

Why do you want four?

May be in future i'll have different networks... But for now only one required.

Ok .. you meant to say that i can simply put the RJ45 cable from my ONT to first interface (WAN) ? (NO any addtional module required)  and how can i use that WAN interface as PPPoE dialer , is there any IOS upgradation required ?

Thanks

Thanks for your support. actually i dont have much experties to work with CISCO routers, Linksys/Dlink no issue... that is why i am asking very basic things just to make sure by an experts.

so i have the following senerio,

I have 2mb PPPoE DSL connection from my ISP ( a fiber connection which terminates on (ONT) at my premises) this gives me one RJ45 cable to connect with my Linksys router's Internet (WAN) port, and i make PPPoE dialer through webbased console and give my user name and password to connect with internet also  there are addtional 4 LAN ports which i can use for my LAN users.

Now i want to replace my Linksys router with CISCO1921/K9 router. how shoud i conncet ?

Hope that above senerio is understaable....

thanks.

First of, the 1921 has two HWIC ports.  You can stick a one-port HWIC-1FE two-port HWIC-2FE FastEthernet card (maximum ONE per appliance).  If you want GigabitEthernet, then you can use EHWIC-1GE-SFP-CU (maximum ONE per appliance).   The modules stated here are Layer-3 capable.  If you want a Layer-2 capable then read on.

Now i want to replace my Linksys router with CISCO1921/K9 router. how shoud i conncet ?

I'm no expert in the Linksys/Cisco SME business line but just WHAT are you trying to achieve?   I mean if you just want a router with four Layer-2 ports then you should consider the EHWIC-4ESG module.

hi leolaohoo,

Thanks for your post. i am trying to achive to connect RJ45 (which is my existing PPPoE internet connection) with 1921 router. So if i connect this RJ45 Cable directly to 1921 integrated 10/100/1000 port. This will work or not ???

Or if you say in another words , that if i want to make 1921 as a PPPoE dialer, what should i need to have ????

thanks

Have you tried searching for guides and learning how things are done with cisco rotuers before asking ?

Otherwise you can contact a Cisco partner and they should be able to help.
