[NSX] Network Namespace in NSX

haewon83 2024. 4. 25. 20:59

Namespace 기술은 NSX에서도 사용됩니다.

내부 LAB 환경에서 실제로 어떻게 구성되어 있고 이를 확인하는 방법을 알아보겠습니다.

우선 Network Namespace의 정의는 Wiki에 다음과 같이 기술되어 있습니다.

https://en.wikipedia.org/wiki/Linux_namespaces

Network (net)
Network namespaces virtualize the network stack. On creation, a network namespace contains only a loopback interface.
Each network interface (physical or virtual) is present in exactly 1 namespace and can be moved between namespaces.
Each namespace will have a private set of IP addresses, its own routing table, socket listing, connection tracking table, firewall, and other network-related resources.
Destroying a network namespace destroys any virtual interfaces within it and moves any physical interfaces within it back to the initial network namespace.

1. ip 명령어를 이용하여 Network Namespace 정보 확인
LAB 환경에는 총 4개의 Network Namespace가 확인되며,
2개는 Load Balancer,
하나는 Tier-0,
나머지 하나는 Tunnel VRF 용도로 확인
