I run with following configuration:
set int state GigabitEthernet0/4/0 up
set int state GigabitEthernet0/5/0 up
set int ip address GigabitEthernet0/4/0 2002::2/64
set int ip address GigabitEthernet0/5/0 192.168.5.2/24
ip route add ::/0 via 2002::1
set int nat64 in GigabitEthernet0/4/0
set int nat64 out GigabitEthernet0/5/0
nat64 add prefix 1:2:3::/96
nat64 add pool address 192.168.50.1 - 192.168.50.19
trace add dpdk-input 100
when nat64 is enabled, and I run *ping6 2002::2%3* in In inside node, the
traffic goes to nat64-in2out and drop packets.
sample trace:
00:00:34:663182: dpdk-input
GigabitEthernet0/4/0 rx queue 0
buffer 0x4839: current data 14, length 104, free-list 0, clone-count 0,

ICMP echo_request checksum 0x54dd
00:00:34:663204: error-drop
ip4-input: ip4 adjacency drop
I think it should go to ip6-lookup not ip4-lookup.
