Problem to use traceroute to VS

Hello all,

 

 

I have a viprion with version 10.0.1 and when I try use traceroute (using TCP protocol) to any VS, I have loop.

 

 

[infra@afrodite ~]$ traceroute www.terra.com.br -U

 

traceroute to www.terra.com.br (200.154.56.80), 30 hops max, 40 byte packets

 

1 terra-v-204-dsw01-poa.tc.terra.com.br (200.176.6.61) 0.461 ms 0.493 ms 0.552 ms

 

2 200.154.63.52 (200.154.63.52) 0.436 ms 0.353 ms 0.597 ms

 

3 200.154.63.50 (200.154.63.50) 0.993 ms 0.909 ms 1.017 ms

 

4 200.154.63.52 (200.154.63.52) 0.401 ms 0.749 ms 0.727 ms

 

5 200.154.63.50 (200.154.63.50) 0.613 ms 0.996 ms 0.661 ms

 

6 200.154.63.52 (200.154.63.52) 0.825 ms 0.353 ms 1.103 ms

 

7 200.154.63.50 (200.154.63.50) 0.575 ms 0.610 ms 1.045 ms

 

:

 

 

But when I use TCP is ok:

 

 

[root@afrodite ~] traceroute www.terra.com.br -T

 

traceroute to www.terra.com.br (200.154.56.80), 30 hops max, 40 byte packets

 

1 terra-v-204-dsw01-poa.tc.terra.com.br (200.176.6.61) 0.539 ms 0.424 ms 0.406 ms

 

2 www.terra.com.br (200.154.56.80) 0.462 ms 0.463 ms 1.797 ms

 

 

Someone have this problem?

 

 

Best regards

    im not sure the F5 is causing this, in the original case i assume the device first hit ( terra-v-204-dsw01-poa.tc.terra.com.br (200.176.6.61) ) is doing some redirect for UDP (probably DNS according to the manpage).

     

    is there also something not working LEO or is this just something you observed?

     

    is it possible you provide similar traceroute output (feel free to obfuscate IPs) and then three times, so with -U / -I and -T ?
