Hi,
I've tested nat64 functionality with ping6 in vpp 1807, the ping
responses after more than 60 seconds. it seems that the ipv6 neighbor
created with a long delay. how can I fixed it?
This is my configuration :
set interface nat64 in GigabitEthernet0/6/0
set interface nat64 out GigabitEthernet0/7/0
set interface ip address GigabitEthernet0/6/0 ::A00:1/64
set int ip address GigabitEthernet0/7/0 192.168.40.154/24
set interface state GigabitEthernet0/6/0 up
set interface state GigabitEthernet0/7/0 up
nat64 add pool address 192.168.40.10 - 192.168.40.100
in host:
ifconfig eth1 inet6 add ::A00:2/64
ip -6 route add 0:0:0:0:0:ffff:c0a8:28fe via ::A00:1
ping6 0:0:0:0:0:ffff:c0a8:28fe
and this is output of trace:
