Hello, >From reading the routing data model: https://fdio-vpp.readthedocs.io/en/latest/gettingstarted/developers/fib20/routes.html#id2 I understand that when I add a static route (using the "ip route add" command) to an attached next hop, VPP will resolve that route, which is triggered (in my case of plain ol' routing) by a successful ARP learning event. What I want is to perform some logic on each of the routes that their attached next-hop is a recently learned neighbor.
Taking the example from the doc: if I use ip route add table 1 64.10.1.0/24 10.0.0.2 GigabitEthernet2/0/1 ip route add table 1 64.10.2.0/24 10.0.0.2 GigabitEthernet2/0/1 then upon learning the MAC of 10.0.0.2 neighbor, I want to be able to programmatically fetch the 64.10.1.0/24 and 64.10.2.0/24 prefixes in that context of neighbor resolution. I've traced down the neighbor learning logic to `ip_neighbor_add` function in `vnet/ip-neighbor/` but I couldn't figure out where VPP performs the route resolution following a neighbor learning event. If I understand the model correctly, a new neighbor IP and MAC triggers a change to the adjacency table. In order to fetch the matching prefixes, I need to be able to iterate over entries of fib_entry_t , for each entry checking the fib_path_t it has, and whether the path's ip_adjancency_t is matching the IP and MAC of the recently learned neighbor. Is my perception correct? Thanks, David
