Inter-AS mVPN Option C Pattern-4 - ASBR로 RR 기능 이동 - StaticRP를 BSR로 변경

13738 단어 multicastVPN시스코

우선



이 검증 내용은 2011년에 MPLS VPN에 대해 실험실에서 확인한 결과를 로컬 위키 서버에 저장했습니다. 그 후, 누군가의 참고가 되었는지 어떨지는 모릅니다만, 이제 wiki 서버도 움직이고 있지 않기 때문에, 아무도 이 내용을 보는 것도 없다고 생각합니다. 그렇지만, 최근이 되어 스스로도 재검토하는 일이 있었으므로, 조금이라도 참고가 된다고 생각해, 이쪽에 올리기로 했습니다.

그림-2


  • 각 AS에서 BSR 사용. (SSM을 사용하지 않음)
  • 각 라우터의 루프백 주소를 AS간에 BGP를 사용하여 광고
  • R1과 R2 사이의 msdp 피어 설정
