I have 6513 switch in my core location which is connected to 7613 router. Router has many WAN links with MPLS and p2p connectivity. If i have load on network like when there is Video conference session then i m getting too much delay from our LAN. It doesnt matter if i ping from my pc or from 6513. In same case if i ping from 7613 then there is no delay. When i checked the interfaces both on router and switch connected to each other , there are drops and also tx and rx load is high. My MPLS connectivity is on router with 10 Mbps link. I m having delay only on those locations which are connected with MPLS . Other locations which are on p2p link , those are working fine. I have changed all my modules and interfaces on both devices but no results. I m doubtful abt my ISP's MPLS . My ISP is BSNL. and BSNL provide us different IP for peering with them on MPLS. We are on private AS peering with Public AS. Now when i tried to ping from router to all locations of MPLS with different source IP then there is also delay on router .so what i saw that when i use source of my own network then i m getting delay but when i use provider's IP as source then there is no problem in latency. Sometimes it seems to me as MPLS problem ,coz there are also big number of drops on this MPLS interface and tx and rx load is high. One very important point is that there are also drops and high tx and rx load on all remote locations which are connected to MPLS.
so plz help me to rectify this issue, its very urgent to me.
thanx and regards,
