예: 레이어 3 네트워크의 SRX 시리즈 방화벽에서 멀티노드 고가용성 구성
이 예는 레이어 3 구축에서 멀티노드 고가용성 설정을 구성하고 확인하는 방법을 보여줍니다.
개요
멀티노드 고가용성에서는 참여하는 SRX 시리즈 방화벽이 레이어 3 네트워크에서 독립적인 노드로 작동합니다. 노드는 서로 다른 네트워크에 속한 인접 인프라에 연결됩니다. 암호화된 논리적 섀시 간 링크(ICL)는 라우팅된 네트워크를 통해 노드를 연결합니다. 참여 노드는 시스템 또는 하드웨어 장애 발생 시 빠른 동기화된 페일오버를 보장하기 위해 서로 백업합니다.
멀티노드 고가용성에서 활성은 서비스 중복 그룹(SRG) 수준에서 결정됩니다. SRG1이 활성화된 SRX 시리즈 방화벽은 유동 IP 주소를 호스팅하고 유동 IP 주소를 사용하여 트래픽을 유도합니다. 페일오버 중에 유동 IP 주소는 이전 활성 노드에서 새 활성 노드로 이동하고 통신 클라이언트 디바이스를 계속합니다.

토폴로지 개요
그림 1 은 이 예에서 사용되는 토폴로지를 보여줍니다.
그림 1: 레이어 3 구축 
의 멀티노드 고가용성
의 멀티노드 고가용성
이 레이어 3 멀티노드 고가용성(MNHA) 구축에서는 두 개의 SRX 방화벽(SRX-01 및 SRX-02)이 라우팅된 인터페이스를 통해 업스트림(R2) 및 다운스트림(R1) 라우터에 연결된 독립적인 라우팅 노드로 작동합니다.
- 각 SRX는 신뢰 및 언트러스트 측에 고유한 인터페이스 IP 주소를 가지고 있습니다.
- 노드는 라우팅된 네트워크(HA 링크)를 통해 섀시 간 링크(ICL)를 통해 상호 연결됩니다.
- 유동 루프백 IP 주소(10.11.0.1/32)는 두 노드 모두에서 구성되며 서비스 중복 그룹(SRG)의 활성 노드가 소유합니다.
- R1(신뢰 측) 및 R2(신뢰할 수 없는 측)의 트래픽은 라우팅 결정(예: BGP 정책)에 따라 활성 노드로 라우팅됩니다.
- 활성 노드는 트래픽을 전달하는 동안 백업 노드는 트래픽을 전달할 준비가 된 상태로 유지됩니다.
- 페일오버 중:
- 유동 IP가 백업 노드로 이동합니다.
- 라우팅 업데이트(예: BGP 메트릭을 통해)는 트래픽을 새 활성 노드로 리디렉션합니다.
- 트래픽은 최소한의 중단으로 계속됩니다.
일반적인 고가용성 구축에서는 네트워크의 노스바운드 및 사우스바운드 양에 여러 라우터와 스위치가 있습니다. 이 예시에서는 SRX 시리즈 방화벽의 양쪽에 있는 두 개의 라우터를 사용하고 있습니다.
이 예시에서는 SRX 시리즈 방화벽 간에 고가용성을 구축하고 HA 링크 암호화를 활성화하여 터널 트래픽을 보호합니다.

의미
명령 출력은 MNHA ICL 링크를 암호화하는 데 사용되는 IPsec SA를 제공합니다. SRX-01과 SRX-02 간의 제어, 라우팅 및 상태 동기화 트래픽을 보호합니다
주의:
명령 출력에 표시된 IP 범위(180.100.1.x)는 ICL IPsec 트래픽 선택기 역할을 합니다. 시스템은 이 IP 범위를 동적으로 할당하므로 변경하거나 수정하지 않는 것이 중요합니다. 또한 더 넓은 180.x.x.x IP 범위에 대해 BFD(Bidirectional Forwarding Detection)가 자동으로 활성화됩니다.
