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.
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.
