Abstract
A method and apparatus for network monitoring using a proxy are disclosed. In one embodiment, a method generally comprises receiving at a proxy, path information for a label switched path (LSP) from a forwarding device located in the LSP, generating a connectivity verification message based on the path information, adding a proxy label to the connectivity verification message, and transmitting the connectivity verification message to the forwarding device. The proxy label is configured to inject the connectivity verification message into a forwarding plane at the forwarding device and the connectivity verification message is configured for transmittal from the forwarding device over the LSP to a destination node to verify a forwarding path associated with the path information received from the forwarding device.
