2017-04-07MPLS McastNeale Ranns1-2/+14
1 - interface-DPO Used in the Data-plane to change a packet's input interface 2 - MPLS multicast FIB entry Same as a unicast entry but it links to a replicate not a load-balance DPO 3 - Multicast MPLS tunnel Update MPLS tunnels to use a FIB path-list to describe the endpoint[s]. Use the path-list to generate the forwarding chain (DPOs) to link to . 4 - Resolve a path via a local label (of an mLDP LSP) For IP multicast entries to use an LSP in the replication list, we need to decribe the 'resolve-via-label' where the label is that of a multicast LSP. 5 - MPLS disposition path sets RPF-ID For a interface-less LSP (i.e. mLDP not RSVP-TE) at the tail of the LSP we still need to perform an RPF check. An MPLS disposition DPO performs the MPLS pop validation checks and sets the RPF-ID in the packet. 6 - RPF check with per-entry RPF-ID An RPF-ID is used instead of a real interface SW if index in the case the IP traffic arrives from an LSP that does not have an associated interface.

2017-04-06BFD-FIB interactionsNeale Ranns1-2/+3
- single-hop BFD: attach a delegate to the appropriate adjacency - multi-hop BFD [not supported yet]: attach a delegate to the FIB entry. adjacency/fib_entry state tracks the BFD session state. when the state is down the object does not contribute forwarding hence and hence dependent objects will not use it. For example, if a route is ECMP via two adjacencies and one of them is BFD down, then only the other is used to forward (i.e. we don't drop half the traffic).

2017-03-08Proxy ND (RFC4389 - or a sub-set thereof). This allows the 'emulation' of ↵Neale Ranns1-0/+6
bridging. That is hosts in one sub-net reachable via differenet interfaces. Introducate a new API command: ip6 nd proxy <host-address> <interface> this indicates 2 things; 1) that host <host-address> is reachable out of interface <interface>. VPP will thus install that route. 2) NS requests sent to <host-address> will be responeded to (i.e. proxied).

2017-03-03python API: work towards python/vpp api separationKlement Sekera1-6/+6
This change improves vpp_papi behaviour by introducing alternate way of calling vpp APIs. The common code is the same: vpp = VPP(...) vpp.connect(...) Calling VPP API is different, instead of deprecated: vpp.show_version() # deprecated one should write vpp.api.show_version() this allows VPP messages like "connect" and "disconnect" to be used, once the old API is dropped (in 17.07). Also part of this patch is a check for name conflict, to prevent VPP object overwriting its own functionality with generated code based on json files.

DHCP additions: 1) DHCPv4 will only relay a message back to the client, if the Option82 information is present. So make this the default. 2) It is no longer possible to select via the API to "insert circuit ID" - since this is now default 3) Remove the version 2 API since it's now the same as version 1. 4) Adding the VSS option is now conditional only on the presence of VSS config (not the 'insert' option in the set API) 5) DHCP proxy dump via API Change-Id: Ia7271ba8c1d4dbf34a02c401d268ccfbb1b74f17 Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-01-27IP Multicast FIB (mfib)Neale Ranns1-1/+33
- 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.
