I have dual 100MB circuits to a production site. Each circuit is connected back to a 3845 router on a gigabit interface. These routers are in turn connected back to 2 core switches 6506E sup720.
When I do a ping test I am getting an average latency of 2ms. The carriers tell me that the delay across the circuit should be <1ms.
I run OSPF across the links and evrything is fine in terms of routing. Its just this delay that seems to be confusing me. The configuation for the interaface is as follows:
description BT 100MB Circuit
ip address 192.168.x.x 255.x.x.x
ip nbar protocol-discovery
ip pim sparse-dense-mode
ip route-cache flow
Is there anything that I can do to troubleshoot the delay?
