traceroute error

nickchang

I login to AX1000 console.
And then, I traceroute 8.8.8.8

But, reply to me :
AX1000-11#traceroute 8.8.8.8
traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 40 byte packets

7 google-public-dns-a.google.com (8.8.8.8) 7.697 ms 7.630 ms 3.620 ms

I don't know why?? It's a wrong route.
But, If I ping 8.8.8.8

AX1000-11>ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=53 time=14.2 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=53 time=15.9 ms
64 bytes from 8.8.8.8: icmp_seq=3 ttl=53 time=15.9 ms

It's Ok.

Can everyone give me a suggest??

Thanks

Hi nickchang,
Do you have DNS server configured (ip dns primary x.x.x.x) on your AX1000? I guess it's something to do with it (or DNS setting). You may want to take a packet capture for traceroute transaction including name resolution.
Thanks.
