Let us say Network A has a peering Agreement with Network B. Now let us say Network X wants to reach Network B. X and B do not have a peering agreement. Can Network A use the peering Link between A nd B to route the traffic of network X.
In the most common sense of the word "peering", no, it cannot.
What are the mechanisms in place in B's network to detect that Network A is transiting the data( in this case network B looser) from Network X?
Network monitoring, statistics, sometime actual packet filters fed from RADB. Sometimes pure luck: one day, a traceroute will reveal the trick.
Basically what I am trying to arrive at is: Suppose the peering arrangement between A and B were to be for data originating from A and B only(and not transited). Can A or B misuse the peering agreement by masquerading transit data as if its originating from its own n/w?
Technically yes (some technical measures can be used against that). But it is a violation of the typical peering agreement and it will raise trouble :-)
