- 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>
2017-09-11FIB table add/delete APINeale Ranns1-3/+95
part 2; - this adds the code to create an IP and MPLS table via the API. - but the enforcement that the table must be created before it is used is still missing, this is so that CSIT can pass. Change-Id: Id124d884ade6cb7da947225200e3bb193454c555 Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-04-07MPLS McastNeale Ranns1-0/+1
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.

use a 32bit mask in the adjacency to AND with the IP address and OR into the rewrite. Change-Id: I80b0f246c18fd74f3e43c5d49e25833412f34665 Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-03-17Fix IP feature ordering.Neale Ranns1-18/+2
Drop comes before lookup when enabled. is_first_or_last is not required when setting a feature, the anchor is added in find_config_with_features(). Don't make the PG interfaces automatically L3 enabled, this way we can have tests that check the L3 protocol disbaled behaviour.

2017-01-27IP Multicast FIB (mfib)Neale Ranns1-0/+612
- 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.
