Name: loopback subnet
Intent: is a /32
Description: This check iterates through all subinterfaces and filters the results to return loopback interfaces where the assigned IP subnet is bigger than a /32.
Query:
foreach device in network.devices
foreach iface in device.interfaces
where iface.loopbackMode
foreach subIface in iface.subinterfaces
foreach addr in subIface.ipv4.addresses
where addr.prefixLength < 32
select { deviceName: device.name,
ifaceName: iface.name,
subIfaceName: subIface.name,
ip: addr.ip,
prefixLength: addr.prefixLength
}
