![#5. Multicast L3 Interface Policy 생성 (Border LEAF 구성)
5 Tenant – “Multicast-Tenant”-
Networking-VRF –”VRF”-Multicast
• L3 Out 인터페이스 그룹 선택
• L3 Out 인터페이스 그룹을 위한
IGMP Policy 및 PIM Policy 선택
[ 주의 ]
PIM Interface는 Routed Interface만
구성이 가능함 !!!
L3 Outside Interface Type 중 SVI
Interface에서는 지원하지 않음](https://image.slidesharecdn.com/acimcastconfig-180418015906/85/ACI-Multicast-6-320.jpg)

ACI Multicast 구성 가이드
- 1. ACI Multicast 구성가이드 2017.04.08 (version 1.0) Cisco Systems Korea / 최우형(whchoi@cisco.com)
- 2. #1. Multicast Enable 1Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • Multicast Enable
- 3. #2. Multicast BridgeDomain 생성 (Internal LEAF 내부 구성) 2 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • Multicast를 사용할 Bridge Domain을 추가
- 4. #3. Multicast IGMPPolicy 생성 3 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • IGMP Policy 생성 Control Parameter 선택 IGMPv2 또는 IGMPv3 선택 기타 Parameter 선택
- 5. #4. Multicast IGMPPolicy 생성 4 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • IGMP Policy 생성 Control Parameter 선택 IGMPv2 또는 IGMPv3 선택 기타 Parameter 선택
- 6. #5. Multicast L3Interface Policy 생성 (Border LEAF 구성) 5 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • L3 Out 인터페이스 그룹 선택 • L3 Out 인터페이스 그룹을 위한 IGMP Policy 및 PIM Policy 선택 [ 주의 ] PIM Interface는 Routed Interface만 구성이 가능함 !!! L3 Outside Interface Type 중 SVI Interface에서는 지원하지 않음
- 7. #6. Multicast IGMPPolicy 생성 (Border LEAF 구성) 6 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • L3 Out 인터페이스 그룹 선택 • L3 Out 인터페이스 그룹을 위한 IGMP Policy 및 PIM Policy 선택 • IGMP Policy 생성 IGMP Interface Policy Name 생성 Control Parameter 구성 IGMP version 선택 기타 Parameters 구성
- 8. #7. Multicast PIMPolicy 생성 (Border LEAF 구성) 7 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • L3 Out 인터페이스 그룹 선택 • L3 Out 인터페이스 그룹을 위한 IGMP Policy 및 PIM Policy 선택 • PIM Policy 생성 PIM Policy Name 생성 Control Parameter 구성 기타 Parameters 구성
- 9. #8. Multicast RP구성 8 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • RP 구성 Static RP 또는 Auto-RP 구성
- 10. #9. Multicast Policy적용 확인
- 11. Multicast Routing 제약사항 1 EX만 PIM Routing 지원 (Non EX 모델은 지원하지 않음) 2 L3 Outside Interface에서 SVI Interface는 PIM Routing을 지원하지 않음 3 PIM을 사용하는 BD를 위해 IGMP Snooping을 반드시 설정해야 함. 4 Multicast 제어를 위한 Contract 구성은 불가
