Goal

Validation for Layer 3 UDN functionality within Kiagnose, focusing solely on intra-cluster networking. The testing will be executed as part of a new checkup, specifically from namespaces where UDN is defined. This validation aims to ensure proper configuration and network isolation of Layer 3 UDNs without involving ingress or egress testing at this stage.

objectives

• Extend Kiagnose to validate the configuration and functionality of Layer 3 UDNs within cluster networking.
• Ensure network isolation and proper routing within namespaces using UDNs.
• Validate overlapping IP address ranges across namespaces, ensuring correct IP management without conflicts.

User Stories

• As a user, I want Kiagnose to validate the configuration of my Layer 3 UDN within my namespace and ensure no misconfigurations or IP conflicts are present.
• As a network administrator, I want Kiagnose to verify that pods within different Layer 3 UDNs in separate namespaces are isolated, ensuring no network traffic leakage.
• As a user, I want to ensure that overlapping IP address spaces across different namespaces using Layer 3 UDNs are handled correctly, with Kiagnose providing diagnostics for any issues.

Non-Requirements

• Ingress/egress traffic and any external network connectivity testing.
• Validation for Layer 2 UDNs or other network types beyond Layer 3.
