Time to live exceeded for some IPs on switch

[Andrei_Tunes]

Hello! We have a problem with two switchs.

So, we have a switch (IP 172.16.35.254) extreme x440 that is a gateway and in a port 20 of this switch we have a proxy server (IP 172.16.32.51) and in another port 48 we have other switch extreme x440 (IP 172.16.35.211). When I try to ping the proxy server on gateway switch, I received this:
SW-DataCenter.24 # ping 172.16.32.51
Ping(ICMP) 172.16.32.51: 4 packets, 8 data bytes, interval 1 second(s).
44 bytes from 172.16.35.254: icmp_seq=0 Redirect Host
44 bytes from 172.16.35.254: icmp_seq=0 Redirect Host

44 bytes from 172.16.35.254: icmp_seq=3 Redirect Host
44 bytes from 172.16.35.254: icmp_seq=3 Time to live exceeded

And, when I run a traceroute I have this:
SW-DataCenter.25 # traceroute 172.16.32.51

What is happening? Someone can help to solve this?

Thanks!!!

Hello Andrei

Do both 440s have ipforwarding turned on for that segment? Can you do a show IPR and past the information of both switches here?

It looks like they are pointing to each other or to another router that has a route to each of them allowing for them to just pass the packet back and forth.

The redirect is when one router knows that there is a second router with that route and redirects it to that second router.

Thanks

No, it is not. I saw this topic, but my problem is different...
