Hello Everyone,
I have a problem with a client complaining about assymmetric routing, I already performed a traceroute from source to destination and backward and for me all seems to be fine, but now the client is complaining about the hops 2 and 3 with IP: 172.31.234.166, he says there's a routing loop and that's why he has its conection with slowness.
Could please share an idea about why a router could answer twice to a traceroute. Thanks in advance.
Router1#tracer vrf vpn-1111 10.135.47.30
