Did you setup the key size of the map and the prefixlen field of bpf_lpm_trie_key correctly ? Because the unit of key_size is in-bytes and it should be the maximal length of these strings, but the unit of prefixlen is in-bits and it is the length of string expressed in bits. And could you share the steps on how you used it ? > Thanks & Regards, > Dominic > > .
