    • How do you determine the most specific network route ONTAP 9.2 and later versions will use for network traffic?

The process is similar in IPv6, but instead of a specifiying a netmask (or more formally, a subnet mask) to define a subnet it use a network prefix; the larger the prefix the smaller the subnet.
    • LIF is unable to reach gateway

      LIF is unable to reach gateway, it is timing out. [  6067] TCP connection to ip 172.xx.xx.xx, port 445 failed: No route to host.

[  6067] TCP connection to ip 172.xx.xx.xx, port 445 failed: No route to host. [  6069] TCP connection to ip 172.xx.xx.xx, port 445 failed: No route to host. [  6072] TCP connection to ip 172.xx.xx.xx, port 445 failed: No route to host. Note: In the above examples, Gateway is configured to be on 192.168.1.1, LIF is configured for 192.168.1.0/24 network, indicating it should be in the same subnet, thus a subnetting mistake is ruled out.
