All,

      Thanks to all those who helped me with my OT post last week. The 2500
with 2 serial and 2 ethernet ints is now running 12.0.17. Adding ip
route-cache policy and ip route-cache same-interface to the policy routing
interfaces (s0 and e0) made an outrageous improvement. My interface
statistics now look like this:

Ethernet0

                        Total 431227 155613385 429988 136691258

. Average utilization dropped from 30% down to 5%. Long live the mighty
2500...
