Description

config utility allows configuration of interfaces with invalid values :

1. network (first address from subnet) and broadcast (last address of subnet) addresses
2. mask lower then 8
3. ip address from reserved special ranges (0.0.0.0/8, 127.0.0.0/8, 224.0.0.0/4, 240.0.0.0/4)
4. values with leading zeros

Steps to reproduce the issue:

1. configure interfaces with ip addresses
   config interface ip add Ethernet32 198.18.32.0/24
config interface ip add Ethernet34 198.18.34.255/24
config interface ip add Ethernet40 10.0.0.0/7
config interface ip add Ethernet42 0.0.0.1/24
config interface ip add Ethernet50 127.0.10.12/32
config interface ip add Ethernet52 100.000.000.001/024
config interface ip add Ethernet56 100.000.000.001/00000
config interface ip add Ethernet58 240.0.0.1/4

2. verify via show run interface

{
    "Ethernet32": {}, 
    "Ethernet34": {}, 
    "Ethernet40": {}, 
    "Ethernet42": {}, 
    "Ethernet50": {}, 
    "Ethernet52": {}, 
    "Ethernet56": {}, 
    "Ethernet58": {}, 
    "Ethernet32|198.18.32.0/24": {}, 
    "Ethernet34|198.18.34.255/24": {}, 
    "Ethernet40|10.0.0.0/7": {}, 
    "Ethernet42|0.0.0.1/24": {}, 
    "Ethernet50|127.0.10.12/32": {}, 
    "Ethernet52|100.000.000.001/024": {}, 
    "Ethernet56|10.10.10.001/00": {}, 
    "Ethernet56|100.000.000.001/00000": {}, 
    "Ethernet58|240.0.0.1/4": {}
}

Describe the results you received:
config utility insert into db invalid ip setting for interface

Describe the results you expected:
config utility should return error and doesnt update db
