I am facing a serious matter with my networks, I have many sites connected with MPLS and I am using the infrastrucutre of one ISP, but since a few days I am not able from one branch( lets call it branch A) to reach four other branches lets say C D E F, but inside the router of this four branches I can reach branch A but not when I am inside the local network of those four branches, when I do a traceroute from branch A to one of those 4 branches, the first hop is one of the private IP address of branch C (which is not normal) and the traceroute doen succeed, normally I have to pass trough the router of the ISP.
please help me to sort out this issue, may be it can be a hacker so please help me.
