Hi all,
I have setup a simple NAT-PT & it didnt work. any help
R1 -ipv6-------R2----ipv4----R4
R1 config:
--------------
interface FastEthernet0/0
ip address 10.1.12.1 255.255.255.0
duplex auto
speed auto
ipv6 address 2001:DB8:3002::1/64
ipv6 enable
Rack1R1#sh ipv6 interface fas0/0
FastEthernet0/0 is up, line protocol is up
IPv6 is enabled, link-local address is FE80::209:7CFF:FE72:4780
Global unicast address(es):
2001:DB8:3002::1, subnet is 2001:DB8:3002::/64
Joined group address(es):
FF02::1
FF02::2
FF02::1:FF00:1
FF02::1:FF72:4780
MTU is 1500 bytes
ICMP error messages limited to one every 100 milliseconds
ICMP redirects are enabled
ND DAD is enabled, number of DAD attempts: 1
ND reachable time is 30000 milliseconds
ND advertised reachable time is 0 milliseconds
ND advertised retransmit interval is 0 milliseconds
ND router advertisements are sent every 200 seconds
ND router advertisements live for 1800 seconds
Hosts use stateless autoconfig for addresses.
R2 Configs:
--------------------
interface FastEthernet0/0
ip address 10.1.12.2 255.255.255.0
service-policy input policypolicetest
duplex auto
speed auto
ipv6 address 2001:DB8:3002::2/64

!
interface FastEthernet0/1
ip address 10.1.4.2 255.255.255.0
duplex auto

ipv6 nat
end
R4 config:
---------------
Rack1R4#sh run inter e0/0
Building configuration...
Current configuration : 92 bytes
!
interface Ethernet0/0
ip address 10.1.4.4 255.255.255.0
half-duplex
no cdp enable
end
problem:
----------------
Ping from R4 to 10.1.12.1 ...does not work.. ??????
Debugging:
--------------
Rack1R2#ping 10.1.12.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.12.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
Rack1R2#ping 2001:db8:3002::1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:DB8:3002::1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
