I having a basic query in troubleshooting E1 link , here im facing packet drop in the link and we are testing by providing local loop and remote loop from the CSU/DSU at local point and at remote point . I have tried ping test while the loop is given at local point and remote point ie i have pinged my local serial interface IP address (eg 10.0.0.1 -local & 10.0.0.2 -remote ) in Remote Loop i could see no errors and drops and also the traffic on the interface output and input is the same(eg input rate 1000bps and output rate 1000bps) .My query is that when i am pinging the local interface IP does the icmp packet travels till the loop point and comes to the same interface(like a boomerang) .Also is this a proper way of testing the link .Kindly provide best practices in checking the issue .
R1 Local CSU/DSU | Remote CSU/DSU (remote loop given )
The link is having packet drop when i ping router A to Router B and it also had in past which was due to Telco end issue , my telco is involved and he did a bert test from router A to till the remote end (Router B )Mux and there was no error in his test so further we are checking the remote end MUx to router part . Also my question here is, when im pinging the self ip address of the router A which is recieving a loop from Remote end CSU /DSU does my packets are going like a boomerang and coming to me because im finding input rate and outrate as the same (also explained above in the diagram ) .
