union { ... } fib_path_t_::fp_nh

dpo_proto_t fib_path_t_::fp_nh_proto

The protocol of the next-hop, i.e.

the address family of the next-hop's address. We can't derive this from the address itself since the address can be all zeros

Definition at line 196 of file fib_path.c.

fib_node_t fib_path_t_::fp_node
