Detailed Description

IPv4 Deduplication Test.

Tests topology:

   /---- B ----\

A -— | -— D -— E ---- C -—/

This test case counts the number of packets received and dropped at each node across the topology. Every node is configured to forward the multicast packet which originates at node A.

With RFC 6621 de-duplication enabled, one 1 packet is received while some number of duplicate relayed packets are dropped by RFC 6621 at each node.

When RFC6621 is disabled, the original packet has TTL = 4. Multiple packets are received at each node and several packets are dropped due to TTL expiry at each node.
