Bandwidth/router upgrade from a T3 (45Mb) to a higher pipe
I'm currently running a Cisco router 2951 with the serial interface connected to the ISP with a bandwith of 45Mb. I would like to upgrade the bandwidth to let's say 150 or 200 Mb. My understanding is that T3 can't handle that bandwidth. I also have 3 free gigaethernet interfaces available in the 2951 router and i was wondering if i could just use one of the gigaethernet to connect to the ISP for a bigger pipe? If that's possible, would i need any special requirement?
Also, what would be a good replacement for 2951, that allow a bigger bandwidth to the ISP and what type of interfaces/card would i use to make that happen?
You will most likely see 75 Mbps. It is time to upgrade to a higher throughput router. The 4331 will do 150 Mbps concurrent up/down with the additional throughput license. You might want to look at a higher router if you go with the 200 Mbps connection. You can definitely use the 2951 with one of the free gigabitethernet interfaces available as long as it is an Ethernet hand-off from the ISP.
