need an inexpensive way to eavesdrop on MPLS connection

Unanswered Question
Jan 25th, 2008

We have a customer that needs to feed the data flowing over an MPLS connection into a software package that audits the content. They want to be able to see if inappropriate content is flowing and if so, to be able to take action on it. Any ideas on the lowest cost way to do this would be appreciated.

This client requirement raises issues about policies, but I'm not here to question policies, but to solve technical problems.

I have this problem too.

You will make the traffic over the core to flow via switche i.e.---> PE-Switch-P.. and enable SPAN and mirror the traffic to a software (ethereal/wireshark) and monitor the data flowing. Those software has the capability to capture the packets with the help of Outer Label(IGP), Inner Label(VPN) and Source/Destination IP address. So you can get the label values in the PE routers and map the values in the software which will show the data flow...
