본 제품에 대한 문서 세트는 편견 없는 언어를 사용하기 위해 노력합니다. 본 설명서 세트의 목적상, 편견 없는 언어는 나이, 장애, 성별, 인종 정체성, 민족 정체성, 성적 지향성, 사회 경제적 지위 및 교차성에 기초한 차별을 의미하지 않는 언어로 정의됩니다. 제품 소프트웨어의 사용자 인터페이스에서 하드코딩된 언어, RFP 설명서에 기초한 언어 또는 참조된 서드파티 제품에서 사용하는 언어로 인해 설명서에 예외가 있을 수 있습니다. 시스코에서 어떤 방식으로 포용적인 언어를 사용하고 있는지 자세히 알아보세요.
Cisco는 전 세계 사용자에게 다양한 언어로 지원 콘텐츠를 제공하기 위해 기계 번역 기술과 수작업 번역을 병행하여 이 문서를 번역했습니다. 아무리 품질이 높은 기계 번역이라도 전문 번역가의 번역 결과물만큼 정확하지는 않습니다. Cisco Systems, Inc.는 이 같은 번역에 대해 어떠한 책임도 지지 않으며 항상 원본 영문 문서(링크 제공됨)를 참조할 것을 권장합니다.
이 문서에서는 Cisco vEdge 라우터의 다양한 BFD(Bidirectional Forwarding Detection) 플랩 사유에 대해 설명합니다.
Cisco는 Cisco SDWAN 솔루션에 대한 지식을 보유하고 있는 것이 좋습니다.
이 문서는 19.2.1을 실행하는 Cisco 클라우드 vEdge 라우터를 기반으로 합니다.
이 문서의 정보는 특정 랩 환경의 디바이스를 토대로 작성되었습니다.이 문서에 사용된 모든 디바이스는 초기화된(기본) 컨피그레이션으로 시작되었습니다.네트워크가 작동 중인 경우 모든 명령의 잠재적인 영향을 이해해야 합니다.
이 문서는 특정 토폴로지로 제한되지 않습니다.
이 문서에서 일부 중요한 구성 요소의 IP 주소 및 색상:
구성 요소 | 시스템-IP | VPN 0 IP/색상 | VPN 0 IP/색상 |
VEDGE-1 | 10.13.13.13 | 192.168.1.4 / mpls | 192.168.2.4 / mpls |
VEDGE-2 | 10.15.15.15 | 192.168.1.8 / 비즈니스 인터넷 | 192.168.2.8 / 비즈니스 인터넷 |
vSmart | 10.8.8.8 | 192.168.1.3 / 기본값 | 해당 없음 |
vManage | 10.7.7.7 | 192.168.1.1 / 기본값 | 해당 없음 |
Cisco vEdge 라우터에서 가능한 'flap-reason' 값은 다음과 같습니다.
1.bfd-deleted - 컨트롤 플레인이 삭제했으므로 BFD가 다운됩니다.
BFD가 삭제되면 두 개의 알림을 발생시킵니다.하나는 BFD가 다운되고 하나는 BFD가 삭제될 때 발생합니다.
2. 시간 초과 - 원격 끝으로부터 BFD 응답이 없습니다.
3. 원격 다운 - 원격 엔드가 BFD 패킷을 전송했으며, 이 패킷은 down-state.4로 이동했음을 나타냅니다.
4.na - 해당 없음이 설정은 BFD 세션이 처음 생성될 때와 BFD 세션이 시작될 때 설정됩니다.
VEDGE-1 라우터에서 포트 홉을 수행하고 다음 시나리오를 재현합니다.
