hi,
I want to test 464XLAT feature of VPP19.04 . I tried to build and configure the
NAT and MAP plugin using this guide:
https://wiki.fd.io/view/VPP/NAT#464XLAT
But some CLI command changed , So I using this Configuration :
client (Linux):
sudo ifconfig enp0s8 up sudo ifconfig enp0s8 192.168.5.1/24 sudo ip route add
192.168.50.0/24 via 192.168.5.2
server (Linux):
sudo ifconfig enp0s10 up sudo ifconfig enp0s10 192.168.50.1/24 sudo ip route
add 192.168.40.0/24 via 192.168.50.2
CE (VPP):
set int state GigabitEthernet0/8/0 up set int state GigabitEthernet0/9/0 up set
int ip address GigabitEthernet0/8/0 192.168.5.2/24 set int ip address
GigabitEthernet0/9/0 9::1/64 ip route add ::/0 via 9::2
map interface GigabitEthernet0/9/0 map-t map interface GigabitEthernet0/a/0
map-t map add domain ip4-pfx 0.0.0.0/0 ip6-pfx 1:2:3::/96 ip6-src 2001:db8::/96
ea-bits-len 0 psid-offset 0 psid-len 0 mtu 9206
PE (VPP):
set int state GigabitEthernet0/9/0 up set int state GigabitEthernet0/a/0 up set
int ip address GigabitEthernet0/9/0 9::2/64 set int ip address
GigabitEthernet0/a/0 192.168.50.2/24 ip route add ::/0 via 9::1 set int nat64
in GigabitEthernet0/9/0 set int nat64 out GigabitEthernet0/a/0 nat64 add prefix
1:2:3::/96
nat64 add pool address 192.168.40.1 - 192.168.40.254
I have some problems on VPP19.04 but VPP18.10 works
*first* : coredump on " show map domain " commands
vpp# show map domain index 1
show map domain: MAP domain does not exists 1
vpp# show map domain index 0

*Second* : MAP-T plugin can not translate IP6 to IP4
at " /vpp/src/plugins/map/ ip6_map_t.c " file , line 537 and " ip6_map_t "
function
p0 = vlib_get_buffer (vm, pi0);
ip60 = vlib_buffer_get_current (p0);
d0 =
ip6_map_get_domain (&ip60->dst_address,
&vnet_buffer (p0)->map_t.map_domain_index,
&error0);
if (!d0)
{ /* Guess it wasn't for us */
vnet_feature_next (&next0, p0);
goto exit;
}
ip6_map_get_domain function can not find map and return 0, so next_node will be
ip6-lookup and icmp6 packet route to PE again !!!
It is a bug , or I used bad configuration ??
