I replied to Tejal privately; here is my answer in case anyone else was
wondering... Better solutions welcome... ;-)

The way to guarantee 512kbps to an IP address block is to rate limit the rest of your address space to "Link-Bandwidth - 512K"...
For example, if you had a 2Mbps circuit, and 192.168.0.0/23 as your address block, with 192.168.1.0/24 for your premium customers, you would do something like:
! interface serial 2/0 rate-limit input access-group 190 1536000 8000 8000 conform-action transmit exceed-action drop ! access-list 190 permit ip any 192.168.0.0 0.0.0.255 access-list 190 deny ip any any !
which will rate-limit inbound traffic to 192.168.0.0/24 to 1536kbps - which means 512kbps guaranteed for 192.168.1.0/24...
Note that this may not work as well as you hope - your upstream provider will still try and send the traffic - it will come across your link, and be thrown away when it comes into your router. So you may have to do some outbound rate limiting too. Best is to experiment to try and get what you want... There is no "command" you can run to do this. If you had control over the router at the other end, you could do a lot more.
