Hi all,

I have the folowing nat configuration on my catalyst 6509-E with a sup720-10G that does not work, and gives a erros messague:

ip vrf testes

rd 6900:5

interface Vlan1111

description liga

ip vrf forwarding testes

ip address 192.168.63.91 255.255.255.248

ip nat inside

interface GigabitEthernet2/30

switchport mode access

switchport access vlan 1111

interface GigabitEthernet2/30

ip vrf forwarding testes

ip address 192.168.63.173 255.255.255.248

ip nat outside

ip nat pool teste_pool 192.168.63.173 192.168.63.173 prefix-length 29

ip nat inside source list 16 pool teste_pool vrf testes overload

access-list 16 permit 128.2.21.0 0.0.0.255

ip route vrf testes 192.168.63.185 255.255.255.255 192.168.63.174

This configuration generates the folowing error:

NAT: translation failed (A), dropping packet s=128.2.21.21 d=192.168.63.185

If i change the nat overload to a static nat, everything

Is there any wrong with this configuration ?

Thanks

Try using "interface g2/30" instead of "pool test_pool".

Also for a single IP, pool prefix-length should be /32
