hi all, i am facing a very strange issue in my remote office. I have 1841 installed with a DXX link terminated on serial interface. IOS is 12.3(11)T5. When i ping any of routers local interface (incl lan and wan IPs), i am getting delays in 800-1500 ms, but at the same time if i ping to any machine on this routers lan, i am getting reply in 100-200 ms. Why is this so ? there is only one link to this router so there is no possibility of assymetric routing. What i am feeling is that router is not responding properly to its local traffic but behaving properly for transient traffic ? what can be the issue. I have checked and cpu utilization is also like 5%-6%. On serial interface reliablity is perfect but i am seeing some CRC but again why only router self packets are suffering ?
