Hi

Invalid source address usually means that the router does not have an interface with that address.

With the addresses yu are entering traceroute would report nothing as they are on the same subnet.

Hi,

You must use IP address of existing IP interface (either physical or Vlan).

e.g.

interface gi 1/1

ip address 10.10.10.10 255.255.255.0

exit

So in traceroute Source address use IP address 10.10.10.10.

Please rate this post if You find it helpful.

Hi,

I just hit some similar issue, with a vrf configuration:

traceroute vrf xxxx ip

Target IP address: 1.1.1.1

Source address: 1.1.1.2

and so on, vrf won't be defined with an ip option but before "ip"

Hope that help.
