Hi Pragash, To update table[FWD] we use the ip6_fib_table_fwding* functions. Tp update table[NON_FWD] we use the ip6_fb_table_entry_* functions.
In both cases the key is the prefix (a/x in your example). In table[FWD] the value is the index of the load-balance object, in table[NON-FWD] the value is the index of the fib_entry_t. If you add this route; Ip route add a/x via b. You’ll first see additions to both tables for b/128 and then additions for a/x.

I have inserted a cuckoo_add code on "ip6_fib_table_fwding_dpo_update" function, but only the <b> ip is getting inserted into my cuckoo filter always. Which function does a/x call to insert into the fib?, i also tried a cuckoo_add inside "ip6_fib_table_entry_insert" but this didnt work as well. I came across this when i made a CLI to display my cuckoo filter, and im pretty sure there is nothing wrong with the cli.
