I am the Service Provider.I have Connectivity between 2 PoP's through 4 No of 2 Mbps Links bundled in a Multilink.Whenever there is a problem like Errors or Reliability issue in any of those LL's I get errors when i Ping other end IP configured on Multilink and as a result my customers face problem and they inform us that they are finding RTO's in their End-to-End Ping Response.
I do monitoring of the Multilink by Polling its IP-Address.Is there a way by which i can monitor those 4 no of 2 Mb Links so that i come to know which Link is having problem,before the customer complains of slow response or RTO's.Can anybody suggest.
