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.

| union { ... } |
| union { ... } |
| ip46_address_t fib_route_path_t_::frp_addr |
The next-hop address.
Will be NULL for attached paths. Will be all zeros for attached-next-hop paths on a p2p interface Will be all zeros for a deag path.
Definition at line 350 of file fib_types.h.
| mpls_eos_bit_t fib_route_path_t_::frp_eos |
EOS bit for the resolving label.
Definition at line 361 of file fib_types.h.
| u32 fib_route_path_t_::frp_fib_index |
The FIB index to lookup the nexthop Only valid for recursive paths.
Definition at line 379 of file fib_types.h.
| fib_route_path_flags_t fib_route_path_t_::frp_flags |
flags on the path
Definition at line 393 of file fib_types.h.
| mpls_label_t* fib_route_path_t_::frp_label_stack |
| mpls_label_t fib_route_path_t_::frp_local_label |
The MPLS local Label to reursively resolve through.
This is valid when the path type is MPLS.
Definition at line 357 of file fib_types.h.
| u8 fib_route_path_t_::frp_preference |
A path preference.
0 is the best. Only paths of the best preference, that are 'up', are considered for forwarding.
Definition at line 389 of file fib_types.h.
| dpo_proto_t fib_route_path_t_::frp_proto |
The protocol of the address below.
We need this since the all zeros address is ambiguous.
Definition at line 341 of file fib_types.h.
| fib_rpf_id_t fib_route_path_t_::frp_rpf_id |
The RPF-ID.
Definition at line 373 of file fib_types.h.
| u32 fib_route_path_t_::frp_sw_if_index |
| u8 fib_route_path_t_::frp_weight |
[un]equal cost path weight
