Typedef Documentation

fib_forward_chain_type_t

typedef enum fib_forward_chain_type_t_ fib_forward_chain_type_t

FIB output chain type.

When a child object requests a forwarding contribution from a parent, it does so for a particular scenario. This enumererates those sceanrios

Configuration for each label value in the output-stack.

fib_mpls_lsp_mode_t

MPLS LSP mode - only valid at the head and tail.

fib_node_index_t

typedef u32 fib_node_index_t

we make this typedef so the code becomes easier for a human to parse.

Protocol Type.

packed so it consumes a u8 only

fib_route_path_flags_t

typedef enum fib_route_path_flags_t_ fib_route_path_flags_t

Path flags from the control plane.

fib_route_path_t

typedef struct fib_route_path_t_ fib_route_path_t

A representation of a path as described by a route producer.

These paramenters will determine the path 'type', of which there are: 1) Attached-next-hop: a single peer on a link. It is 'attached' because it is in the same sub-net as the router, on a link directly connected to the route. It is 'next=hop' since the next-hop address of the peer is known. 2) Attached: the next-hop is not known. but we can ARP for it. 3) Recursive. The next-hop is known but the interface is not. So to find the adj to use we must recursively resolve the next-hop. 3) deaggregate (deag) A further lookup is required.

fib_rpf_id_t

typedef u32 fib_rpf_id_t

An RPF-ID is numerical value that is used RPF validate.

An entry has-a RPF-ID, when a packet egress from (e.g. an LSP) it gains an RPF-ID, these two are compared for the RPF check. This replaces the interfce based chack (since the LSP has no associated interface.

fib_special_type_t

typedef enum fib_special_type_t_ fib_special_type_t

Enurmeration of special path/entry types.

Enumeration Type Documentation

fib_forward_chain_type_t_

enum fib_forward_chain_type_t_

FIB output chain type.

When a child object requests a forwarding contribution from a parent, it does so for a particular scenario. This enumererates those sceanrios

Enumerator
FIB_FORW_CHAIN_TYPE_UNICAST_IP4	Contribute an object that is to be used to forward IP4 packets.
FIB_FORW_CHAIN_TYPE_UNICAST_IP6	Contribute an object that is to be used to forward IP6 packets.
FIB_FORW_CHAIN_TYPE_MPLS_NON_EOS	Contribute an object that is to be used to forward non-end-of-stack MPLS packets.
FIB_FORW_CHAIN_TYPE_BIER	Contribute an object that is to be used to forward BIER packets.
FIB_FORW_CHAIN_TYPE_MPLS_EOS	Contribute an object that is to be used to forward end-of-stack MPLS packets. This is a convenient ID for clients. A real EOS chain must be pay-load protocol specific. This option is converted into one of the other three internally.
FIB_FORW_CHAIN_TYPE_MCAST_IP4	Contribute an object that is to be used to forward IP4 packets.
FIB_FORW_CHAIN_TYPE_MCAST_IP6	Contribute an object that is to be used to forward IP6 packets.
FIB_FORW_CHAIN_TYPE_ETHERNET	Contribute an object that is to be used to forward Ethernet packets.
FIB_FORW_CHAIN_TYPE_NSH	Contribute an object that is to be used to forward NSH packets. This is last in the list since it is not valid for many FIB objects, and thus their array of per-chain-type DPOs can be sized smaller.
