traceroutes showing originating IP

[Ernesto Borges]

When I do trace routes to this nexus switch, it lists at the end the originating IP, no matter from what other router or switch I am using to do the traceroute.  This is an example:

Ash-Core-SW1#trace 10.240.103.254

Type escape sequence to abort.

Tracing the route to 10.240.103.254

VRF info: (vrf in name/id, vrf out name/id)

  1 10.1.10.253 0 msec 0 msec 8 msec

  2 10.1.1.253 0 msec 0 msec 0 msec

  3 10.1.7.1 8 msec 9 msec 0 msec

  4 10.202.1.50 50 msec 59 msec 50 msec

  5 10.1.10.254 50 msec 58 msec 51 msec --> this is the interface originating the trace

Ash-Core-SW1#sh ip int bri

Interface              IP-Address      OK? Method Status  Protocol

GigabitEthernet1/0/22  10.1.10.254     YES NVRAM    up       up  

Any help is highly appreciated

Thank you

That is normal for Cisco IOS.

Hi, Ernesto,

There seems some looping issue, Can you please show us the full traceroute report?

Thank you for your reply, I am sorry I am not following you, what do you mean by full traceroute report? Just in case, here is an extended trace:

Ash-Core-SW1#trace

Hi,

Your second traceroute is different from the first one, please compare 5th hop in both.

In first, it is

  5 10.1.10.254 50 msec 58 msec 51 msec --> this is the interface originating the trace

In second, it is

5 192.168.1.254 59 msec 50 msec 50 msec

Second trace is what it should be and looks correct, did anything change?

Hello, no, I just used a different source IP for the trace
