Hi you guys,
I have one problem with NAT-PT, so i need yr help, you guys.
My topology as below:
R4(S0/1)------------ppp----------------(S0/1)R1(S0/0)-----------------FR------------------(S0/0)R2
<----------ipv6
only-----------------------------><----------------------ipv4
only---------------------->
14::4/64............................14::1/64 |||||||
172.16.123.1/24......................172.16.123.2
My configuration:
R4:
!
!
interface Serial0/1
no ip address
ipv6 address 14::4/64
ipv6 address FE80::14:4 link-local
ipv6 rip RIPng enable
clock rate 2000000
!
R1:
!
interface Serial0/0
ip address 172.16.123.1 255.255.255.0
encapsulation frame-relay
ipv6 nat
clock rate 2000000
frame-relay map ip 172.16.123.2 102 broadcast
no frame-relay inverse-arp
!
interface Serial0/1
no ip address
ipv6 address 14::1/64
ipv6 address FE80::14:1 link-local
ipv6 nat
ipv6 rip RIPng enable
clock rate 2000000
!
ipv6 router rip RIPng
redistribute connected metric 1
!
ipv6 nat v4v6 source 172.16.123.2 1414::1
ipv6 nat v6v4 source 14::4 172.16.123.100
ipv6 nat prefix 1414::/96
!
R2:
!
interface Serial0/0
ip address 172.16.123.2 255.255.255.0
encapsulation frame-relay
clock rate 2000000
frame-relay map ip 172.16.123.100 201
frame-relay map ip 172.16.123.1 201 broadcast
no frame-relay inverse-arp
!
Testing my configuration
R4#ping 1414::1 repeat 200
Type escape sequence to abort.
Sending 200, 100-byte ICMP Echos to 1414::1, timeout is 2 seconds:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
It hadn't any problem with my above configuration, but when I had a little
bit change, it was not good.
My change as below:
R1:
!
no ipv6 nat v6v4 source 14::4 172.16.123.100
ipv6 nat v6v4 source 14::4 10.10.10.100
!
R2:
!
ip route 10.10.10.0 255.255.255.0 172.16.123.1
!
!
Problem: R4 ping ipv6 NAT address 1414::1, success rate is 50% as below:
R4#ping 1414::1 repeat 100
Type escape sequence to abort.
Sending 100, 100-byte ICMP Echos to 1414::1, timeout is 2 seconds:
!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.
!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.
Success rate is 50 percent *(50/100*), round-trip min/avg/max = 84/169/284
ms
I didn't understand why i have received that result (success 50/100), give
me some explanations.
Thanks in advance,
