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

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:

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?
