목차
소개
이 문서에서는 Cisco IOS® XR에서 mVPN(Multicast VPN) 프로파일 14의 문제를 해결하는 방법을 설명합니다.
사전 요구 사항
Multicast profile14 및 그 동작에 대한 지식이 있어야 합니다.
요구 사항
MVPN BGP 자동 검색을 구성하는 것이 좋습니다.
또한 다음 항목에 대해 아는 것이 좋습니다.
- 프로파일 - 14
- 코어 트리 - mLDP
- 서비스 - IPv4 VPN
- C-Overlay Signaling - BGP
- 자동 검색 - BGP
- 모델 - BGP AD를 사용하는 파티션 MDT P2MP
- 캡슐화/전달 - MPLS
사용되는 구성 요소
이 문서는 특정 소프트웨어 및 하드웨어 버전으로 한정되지 않습니다.
이 문서의 정보는 특정 랩 환경의 디바이스를 토대로 작성되었습니다. 이 문서에 사용된 모든 디바이스는 초기화된(기본) 컨피그레이션으로 시작되었습니다. 현재 네트워크가 작동 중인 경우 모든 명령의 잠재적인 영향을 미리 숙지하시기 바랍니다.
mLDP 개념
코어 트리 - mLDP
- 다중 지점 LDP = LDP + 확장
- P2MP 트리 - 수신기 기반 - 라우팅을 통해 학습된 루트
- MP2MP 트리 - 구성 중심 - 루트 구성됨
- MPLS TE 또는 LFA(Loop-Free Alternate)에 의한 보호
- PHP 없음 - 트리를 식별하는 상위 레이블
- 코어 라우터에서 멀티캐스트 복제
- FEC elements hold: Type of tree + Root + Opaque 값: (S, G), MDT 번호, LSP ID
mLDP
MP2MP LSP 대 P2MP LSP
PE 간에 트래픽을 전송하는 방법은 두 가지가 있습니다.
1. MP2MP - 정적 기본 MDT가 해당 특정 사용자에 대한 모든 PE에서 생성되며, 이는 해당 사용자에 대한 모든 PE가 동일한 LAN 세그먼트에 연결된 것처럼 작동합니다.
2. P2MP - 구성 가능한 임계값에 도달하면 발신자 PE가 새 LSP를 생성하여 해당 통신에 관여하는 PE만 트래픽을 볼 수 있도록 합니다. 이 LSP는 스트림에 합류하지 않은 PE로 트래픽을 전송하는 대역폭을 불필요하게 낭비하지 않도록 합니다. 이 LSP는 사용자 네트워크의 (S, G) 항목에 대해서만 생성되며, 구성된 임계값을 초과하는 트래픽을 (*, G) 항목을 통해 전송할 경우 새로운 P2MP가 생성되지 않습니다(leaf가 루트로 작동할 경우 이 시나리오에서 PHP의 개념을 사용할 수 없으며, 그렇지 않으면 해당 트래픽이 속한 사용자를 알지 못함).
mLDP는 루트라는 개념으로 작동하며 PIM-SM 시나리오의 Rendezvous Point와 다소 유사하지만, mLDP에서는 PIM-free MPLS 코어가 언급되고 PIM은 사용자 대면 인터페이스에서만 활성화된다는 점에 유의하십시오.
MP2MP 트리에서 루트는 leaf에서 트래픽을 수신하고 직접 연결된 모든 인접 디바이스에 복제합니다.
모든 PE는 둘 이상의 루트를 구성할 수 있으며 메트릭이 동일하면 메트릭을 기반으로 활성 루트를 선택합니다. 가장 높은 IP 주소가 해당 특정 PE의 루트로 선택됩니다.
P2MP 트리에서 루트는 항상 트래픽을 전송하는 디바이스입니다(이 문서에서는 루트라는 용어가 지정되지 않는 한 MP2MP 트리를 참조하는 데 더 많이 사용됩니다).
P2MP 및 MP2MP
재귀적 전달
재귀적 전달은 mLDP 제어 평면에서 전달 평면에 대한 (다운스트림 ID, 발신 레이블)만 프로그래밍하는 것을 의미합니다. 다운스트림 ID는 일반적으로 다운스트림 노드의 LDP 라우터 ID입니다. 포워딩 플레인에서는 다운스트림 디바이스에 대한 연결성을 재귀적으로 확인하고 실제 발신 인터페이스 및 nexthop를 계산합니다. 재귀적 포워딩은 ECMP/LAG 로드 밸런싱, LFA, RSVP-TE 보호 등의 기능을 활성화합니다. 안타깝게도 모든 플랫폼이 이를 지원하는 것은 아닙니다.
비재귀 포워딩을 사용하면 mLDP는 다운스트림 라우터에 대한 발신 인터페이스 및 NH를 결정하고 포워딩 플레인에서 명시적으로 프로그램(Intf, NH, Outgoing label)합니다.

이 개념은 문제 해결 섹션에서 설명합니다. 이 컨피그레이션은 MID 및 BUD 라우터에 필요합니다.
Head/Root = 이 라우터에 연결된 멀티캐스트 소스가 있음
Tail/Leaf = 이 라우터에 멀티캐스트 수신기가 있음
Bud = 이 라우터는 전송 중이며 일부 수신기가 연결되어 있습니다.
Mid = 이 라우터가 전송 중입니다.
LSM(Label Switch Multicast)/NG mVPN
- Leverage MPLS encapsulation(MPLS 캡슐화 활용) > 유니캐스트로 제어 및 데이터 평면 공유
- 새로운 코어 트리 프로토콜 활용 > mLDP, P2MP TE, BIER
- FRR(빠른 경로 재지정)
- 검증된 기능 활용: 기본 및 데이터 MDT
- VPN당 더 유연한 설계
- 관리 용이성: VPN/기본/데이터 MDT당 멀티캐스트 그룹을 추적할 필요가 없음
BGP
AF IPv4 mVPN
NG 프로파일을 지원할 수 있도록 AF IPv4 mVPN이 추가되었습니다. 이를 MCAST-VPN NLRI라고 합니다.
이 주소 패밀리의 두 가지 주요 기능은 다음과 같습니다.
- 자동 검색(AD)
- 오버레이의 고객 신호
자동 탐색은 PE 라우터가 자동 방식으로 서로 학습함을 의미합니다. PE 라우터는 어떤 다른 PE 라우터가 VPN용 멀티캐스트에 대해 활성화되었는지 파악합니다. 따라서 모든 PE 라우터에서 수동으로 구성할 필요가 없습니다.
오버레이의 사용자 시그널링은 (*, G) 또는 (S, G) 정보의 시그널링이지만, 지금은 PIM이 아닌 BGP에 있습니다.
그림 A에서 BGP AD IPv4 MVPN의 개요를 확인하십시오.
그림 A - BGP IPv4 AD MVPN
AF IPv4 MVPN에는 BGP에서 수행하는 두 가지 중요한 정보가 있습니다. 정보의 첫 번째 부분은 NLRI 자체에 있습니다. 경로 유형을 나타내는 1~7의 숫자가 있습니다. 각 경로 유형에는 특정 기능이 있습니다. 처음 5는 BGP-AD에 사용됩니다. Route Type 3은 실제로 S-PMSI(Data MDT) 시그널링에도 사용됩니다.
마지막 두 가지 유형인 6과 7은 C 멀티캐스트 시그널링에 사용됩니다. Route Type(경로 유형) 옆에는 RD(VPN 컨텍스트가 사용되는 경우), 특정 C-멀티캐스트 정보(소스, 그룹) 및 발신자의 IP 주소(PE)와 관련된 특정 경로 유형 정보도 포함됩니다.
두 번째 부분은 PMSI 터널 특성(PTA)입니다. 이 PTA는 사용되는 코어 트리 터널과 관련된 정보를 보유합니다. 터널 유형은 터널을 구축하는 데 사용되는 코어 트리 프로토콜의 수를 나타냅니다. 터널 식별자는 특정 코어 트리 프로토콜 필드별로 터널을 고유하게 설명하는 필드 집합입니다.
