Abstract

Mechanisms and systems are provided to trace multiple Bit Forwarding Egress Routers BFERs of a Bit Index Explicit Replication BIER architecture in which multicast data packets are forwarded This allows detecting all Equal Cost Multi Paths ECMPs for a plurality of BFERs in the BIER architecture In addition failures such as black holes and data plane control plane inconsistencies ECMP inconsistencies in the BIER architecture can be detected The techniques described herein use a proxy mode to relay an echo request packet from node hop to node instead of using Time to Live TTL techniques
