두 개의 콤보 인터페이스를 연결할 수 없습니다. 제안 사항이 있습니까?

두 개의 콤보 인터페이스를 연결할 수 없습니다. 제안 사항이 있습니까?

코드 작성을 시작하기 전에 상황을 설명하겠습니다. 두 개의 인터페이스를 설정하여 함께 결합한 다음 이 조합에서 브리지를 만들려고 합니다.

저는 RHCE에 대해 배워왔고 이것이 테스트에 나타날 수도 있다고 생각하여 내려놓으려고 노력했지만 모든 테스트에서 제대로 작동하지 못했습니다. 설정이 끝나면 브리지가 존재하는 것처럼 보이지만 브리지에 할당된 IP가 없으며 게이트웨이를 핑할 수 없습니다.

테스트 환경은 kvm의 가상머신이며 내부 네트워크를 사용해왔습니다.

답변1

  1. 이제 ifcfg-brteam0에 정의되어 있으므로 ifcfg-team0에서 IP 매개변수(BOOTPROTO, ...)를 제거할 수 있습니다.

    ifcfg-team0은 다음과 같이 짧을 수 있습니다.

    DEVICE=team0
    TEAM_CONFIG="{\"runner\": {\"name\": \"activebackup\"}}"
    DEVICETYPE=Team
    NAME=team0
    UUID=75299245-c21f-4bfc-8c21-1728378d5a33
    ONBOOT=yes
    BRIDGE=brteam0
    
  2. ifcfg-brteam0에서 DEVICE 값을 수정해야 합니다. 예를 들면 다음과 같습니다.

    DEVICE=brteam0
    

    ifcfg-team0은 이미 OP에서 team0 대신 이 값을 사용하고 있습니다.
