2 ISP Handoffs on single Router

[Lee Dress]

I have 2 ISP 50 MB Fiber/Ethernet Handoffs. 

Currently I'm using 2 881 routers one for each handoff.

These are barely sufficient if not throttling my connections right now, and certainly don't allow me to upgrade my circuits to 100 or better.

each ISP gives me a /28 block of internet addresses that I need to be able to use, and each one of those blocks needs to be able to route 0.0.0.0 back to the ISP.

I would like to know if anyone is doing this, and what equipment you are using.

I've been told by some Cisco sales support guys that I can use a 2921 with a SFP/1GE EHWIC card, and a 4 PORT Ethernet Switch card.  

I need to be sure that each subnet can route all traffic back to their respective ISP, or I'll just  go with 2 smaller routers

I apologize if this was discussed before, I could not find anything when I searched.

Thanks in advance,

Lee

Attachment might help in selecting a suitable router.

Thank you.

From that chart, what I'm using is sufficient for basic Ethernet handoff,

but is there a router that can handle 2 ISP handoffs?

My Current routing on each router is basically like this:

ISP ------- FE/0------ROUTER------FE/1-----ISP /28 block

ip route 0.0.0.0 "FE/0 address"  for /28 block from ISP

I'd like something like this:

ISP-A ---GE/0                     GE/1--- ISP A /28 block

                |-----ROUTER -----|

ISP-B ----GE/2                    GE/3--- ISP B /28 Block

IP route 0.0.0.0 GE/0 address for ISP-A block

IP route 0.0.0.0 GE/2 address for ISP-B block

Of course I would need 4 ports for something like this, but the routing to each is the most important piece.

From a packet forwarding aspect, number of ISPs (when not pulling full Internet tables), or interfaces, doesn't make much of a difference, it's the aggregate volume of packets being forwarded that's usually most important.

On ISRs, module port can be limited by the module interface (and can be difficult to find what those interfaces actually support).
