Hi Vladimir,
I have been using rte_fib for a while and stumbled upon a few quirks.
I was wondering if you would answer some questions:
1) Is it OK/safe to share the same fib to perform route lookups from
multiple lcores in parallel? So far my observations seem to validate
that assumption but I would like your opinion :)
2) Is it OK/safe to modify a fib from a control thread (read/write)
while it is used by data path threads (read only)?
3) There is no public API to list/walk all configured routes in a fib.
Would that be possible/easy to implement?
4) In rte_fib, every IPv4 address (route *and* next hop) needs to be in
host order. This is not consistent with fib6 where addresses are
stored in network order. It took me quite a while to figure out what
was wrong with my code.
I assume this is because DIR24 needs host order integers and not
TRIE. Why was this not hidden in the API?
Could we add a flag to rte_fib_conf to change the behaviour? This
would avoid error prone ntohl/htonl juggling.
Thanks in advance for your replies :)
