Costum Validtion for Prefix overlapping

[GSeiNet]

Hi all,

is it possible to define a costum validation to prevent overlapping prefixes.

For example:
10.10.10.0/24
10.10.10.0/25 is possible to create this prefix, it is a child from 10.10.10.0/24.

any example for this?

Thanks

Hi,

i have only one way to this, based on prefix info / _depth. In my enviroment i want to do this.

Prefix overlap

from extras.validators import CustomValidator

class MyValidator(CustomValidator):

def validate(self, instance):
    from ipam.models import Prefix
	
	"if instance._depth => '2' --> and vrf empty" 		
        self.fail("Prefix overlaps", field'prefix')
	
	or
    
	"if instance._depth => '3' --> and vrf not empty"  
        self.fail("Prefix overlaps", field'prefix')

CUSTOM_VALIDATORS = {
'ipam.prefix': (
MyValidator(),
)
}

I don´t know how i can define "if instance._depth => '3' --> and vrf not empty" .
I hope someone understand me, what i try to do

Best regards
