I am having consisted bad performance from one of our routers. When trying to troubleshoot the problem I have looked at cpu usage both ends are a 5% on ave. Checked router tables and dialler configs and access list alike.
But when I connect to Route A and ping router B ave ping 30ms OK then connect to router B ping router A ave ping 200ms or more.
The other thing I have noticed that on looking at the dialler states it will often show that router B is putting out say txload 200/255, rxload 1/255 let say. Were as router a is receiving txload 1/255, rxload 100/255 on the corresponding dialler int. This seem to imply a bad line but I have had our telecommunication company check this out.
Have you any suggestions to what it may be and a place to look.
