- see draft-ietf-bier-mpls-encapsulation-10 - midpoint, head and tail functions - supported payload protocols; IPv4 and IPv6 only. Change-Id: I59d7363bb6fdfdce8e4016a68a9c8f5a5e5791cb Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-11-07UDP Encapsulation.Neale Ranns1-2/+10
A UDP-encap object that particiapates in the FIB graph and contributes DPO to teh output chain. It thereofre resembles a tunnel but without the interface. FIB paths (and henace routes) can then be created to egress through the UDP-encap. Said routes can have MPLS labels, hence this also allows MPLSoUPD. Encap is uni-directional. For decap, one still registers with the UDP port dispatcher. Change-Id: I23bd345523b20789a1de1b02022ea1148ca50797 Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-10-19Remove unused 'not_last' parameter from ip_add_del_routeMarek Gradzki1-3/+0
Vat supports setting value for the parameter, but 'not_last' is ignored by ip_add_del_route handler, so can be removed. This patch - updates ip.api, - removes vat handlers - updates vpp_papi_provider.py (also mpls_route_add_del with unused not_last) Change-Id: Ife15de123db4bc8247103a29b90bce1988e46534 Signed-off-by: Marek Gradzki <mgradzki@cisco.com>
2017-10-15Revert "Enforce FIB table creation before use"Florin Coras1-0/+3
This reverts commit f9342023c19887da656133e2688a90d70383b0c5. Reverting to unblock master. No idea why jjb +1ed this patch! On closer inspection it looks like it -1ed it and subsequently changed opinion. CSIT tests should be fixed before re-merging.

2017-10-05Distributed Virtual Router SupportNeale Ranns1-0/+1
A distributed virtual router works by attmpeting to switch a packet, but on failing to find a local consumer (i.e. the packet is destined to a locally attached host) then the packet is sent unmodified 'upstream' to where the rest of the 'distributed' router is present. When L3 switching a packet this means the L2 header must not be modifed. This patch adds a 'l2-bridge' object to the L3 FIB which re-injects packets from the L3 path back into the L2 path - use with extreme caution.

2017-07-18FIB path preferenceNeale Ranns1-1/+4
Paths are given a preference, lowest value is 'best'. Only paths that are up are up contribute to fprwarding - that's unchanged. What's new is that of the path's that re up only those that have the best preference contribute. A poor man's primary and backup. It's not true primary/backup function because the FIB must converge before the lower preference paths are used.

2017-04-07MPLS McastNeale Ranns1-0/+3
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.

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).

2017-02-13Augment IP_DETAILS, IP_ADDRESS_DETAILS with a few context fields.Jon Loeliger1-0/+3
When handling the IP_DETAILS and IP_ADDRESS_DETAILS replies, it is almost certainly going to require having both the is_ipv6 and sw_if_index context to handle them properly. Placing these values in an essentially global location as the current VAT does isn't thread-safe. Fruthermore, rather than forcing every API user to hoop-jump to establish these context values, simply provide them in their DETAILS reply messages.

2017-01-27IP Multicast FIB (mfib)Neale Ranns1-0/+53
- 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.
