                                 requires  (described above) 
                                 and gateway IP address
      -d|--del                   Delete route from the VMkernel. 
                                 Requires  (described above)
      -l|--list                  List configured routes for the VMkernel
      -n|--neighbor-list         Show Neighbor Cache entries for the VMkernel
      -f|--family  or    Address family to work on.
                                 Defaults to V4.
      -N|--netstack                Netstack Instance
      -r|--restore               Restore route setting to configured values

    If no options are specified then it will print the default IPv4 gateway.
    The default IPv4 gateway can be set directly as : esxcfg-route 
    Examples:
      To add a route to 192.168.100.0 network through 192.168.0.1
          esxcfg-route -a 192.168.100.0/24 192.168.0.1
          or
          esxcfg-route -a 192.168.100.0 255.255.255.0 192.168.0.1
      To set the VMkernel default gateway of 192.168.0.1
          esxcfg-route 192.168.0.1
          or
          esxcfg-route -a default 192.168.0.1
      To delete a 192.168.100.0 route from the VMkernel:
          esxcfg-route -d 192.168.100.0/24 192.168.0.1
      To view the IPv4 ARP table:
          esxcfg-route -n
      To add a route to  2001:10:20:253::/64 network through 2001:10:20:253::1
          esxcfg-route -f V6 -a 2001:10:20:253::/64 2001:10:20:253::1
      To set the VMkernel default gateway of 2001:10:20:253::1
          esxcfg-route -f V6 -a default 2001:10:20:253::1
      To delete a 2001:10:20:253:: route from the VMkernel:
          esxcfg-route -f V6 -d 2001:10:20:253::/64 2001:10:20:253::1
      To view the IPv6 Neighbor cache:
          esxcfg-route -f V6 -n
