Abstract

See full text

Methods, apparatus, systems and articles of manufacture (e.g., physical storage media, such as storage devices and/or storage disks) to implement label stack identification for lawful interception of virtual private network traffic are disclosed. Example methods disclosed herein can include detecting a trigger that is to cause synchronization of label stack data associated with first virtual private network traffic to be intercepted, the label stack data used to route the first virtual private network traffic in a network. Such example methods can also include, in response to detecting the trigger, initiating execution of a first command on a first router in the network to determine a first label used to route the first virtual private network traffic in the network. Such example methods can further include determining a current label stack for the first virtual private network traffic based on the first label.
