If you want a fixed amount of bandwidth, do the following on R1:
!
access-list 150 permit ip 1.2.3.0 0.0.0.255 any
access-list 150 permit ip host 4.3.2.1 any
!
interface Serial4/1/0
ip address 1.2.3.4 255.255.252.0 (or ip unnumbered Loopback0, whatever)
rate-limit output access-group 150 15000000 24000 32000 conform-action transmit exceed-action continue
rate-limit output 20000000 24000 32000 conform-action transmit exceed-action drop
ip route-cache distributed
!
This reserves 15 Mbps for anything in ACL 150. Don't use this on a
VIP2-40 if the total port speed of all adapters in it exceeds 45 Mbps,
or if you're not using dCEF (which this won't work without).
If you only want DiffServ-style priority queuing, follow the suggestions
by other posters.
