From 32e1c010b0c34fd0984f7fc45fae648a182025c5 Mon Sep 17 00:00:00 2001 From: Neale Ranns Date: Tue, 22 Nov 2016 17:07:28 +0000 Subject: IP Multicast FIB (mfib) - IPv[46] mfib tables with support for (*,G/m), (*,G) and (S,G) exact and longest prefix match - Replication represented via a new replicate DPO. - RPF configuration and data-plane checking - data-plane signals sent to listening control planes. The functions of multicast forwarding entries differ from their unicast conterparts, so we introduce a new mfib_table_t and mfib_entry_t objects. However, we re-use the fib_path_list to resolve and build the entry's output list. the fib_path_list provides the service to construct a replicate DPO for multicast. 'make tests' is added to with two new suites; TEST=mfib, this is invocation of the CLI command 'test mfib' which deals with many path add/remove, flag set/unset scenarios, TEST=ip-mcast, data-plane forwarding tests. Updated applications to use the new MIFB functions; - IPv6 NS/RA. - DHCPv6 unit tests for these are undated accordingly.
