Abstract
The subject matter of this specification can be implemented in, among other things, a method that includes receiving, at a first network device that is associated with an MVPN, an mtrace message that identifies a source device that is associated with the MVPN and that is separated from the first network device by an MPLS network. The method further includes determining an LSP from the first network device to a second network device that is associated with the MVPN and that is separated from the first network device by the MPLS network. The method further includes adding an IP header to the mtrace message, the IP header including a destination address set to a localhost loopback IP address. The method further includes encapsulating the mtrace message with an MPLS label stack that causes the encapsulated mtrace message to reach an instance of the MVPN on the second network device.
