2017-04-01MTRIE Optimisations 2Neale Ranns1-0/+1
1) 16-8-8 stride. Reduce trie depth walk traded with increased memory in the top PLY. 2) separate the vector of protocol-independent (PI) fib_table_t with the vector of protocol dependent (PD) FIBs. PD FIBs are large structures, we don't want to burn the memory for ech PD type 3) Go straight to the PD FIB in the data-path thus avoiding an indirection through, e.g., a PLY pool.

2017-03-17Attached hostsNeale Ranns1-0/+7
allow this config to function: set int ip address loop0 169.254.1.1/32 (the default GW address for attached hosts) set int unnumbered af_packet0 use loop0 ('enable' IP on the host interface) ip route add 192.168.1.1/32 via af_packet0 (where to find the host) repeat for each host and host interface. Inter-host communication is throught the /32 routes. To allow this: 1 - attached host routes have the ATTACHED flag set, so the ARP code accepts then as legitimate sources 2 - unnumbered interfaces inherit the source address from the IP interface Change-Id: Ib66c5f0e848c528f79372813adc3a0c11b50717f Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-01-27IP Multicast FIB (mfib)Neale Ranns1-29/+62
- 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.
