Hướng dẫn cấu hình PBB với Multihomed EVPN

Ví dụ này trình bày cách tích hợp Provider Backbone Bridging (PBB) với Ethernet VPN (EVPN). Với sự tích hợp này, hoạt động của control plane trong lõi mạng sẽ được đơn giản hóa, giúp tăng tốc độ hội tụ (faster convergence) và cải thiện khả năng mở rộng (scalability) so với EVPN thông thường. Ứng dụng điển hình của mô hình PBB-EVPN bao gồm: Kết nối liên trung tâm dữ liệu (Data Center Interconnect – DCI). Các dịch vụ Ethernet dạng E-LAN cho nhà cung cấp dịch vụ (Carrier Ethernet E-LAN services)

Yêu cầu hệ thống

Ví dụ này sử dụng các thành phần phần cứng và phần mềm sau:

4 thiết bị PE (Provider Edge) kết nối đến 2 site khách hàng dạng multihomed, mỗi PE cũng được kết nối đến một host.
2 thiết bị CE (Customer Edge) cấu hình dạng multihomed.
Tất cả các thiết bị PE chạy Junos OS phiên bản 17.2R1 hoặc cao hơn.

Chuẩn bị trước khi triển khai

Trước khi cấu hình, cần thực hiện các bước sau:

Cấu hình các cổng giao tiếp trên thiết bị.
Cấu hình giao thức định tuyến IGP (ví dụ OSPF) trên tất cả thiết bị PE.
Thiết lập phiên BGP nội bộ giữa các thiết bị PE.
Kích hoạt RSVP trên các thiết bị PE.
Cấu hình MPLS và thiết lập đường chuyển mạch nhãn (Label-Switched Paths – LSPs) giữa các PE.

Tổng quan và Mô hình mạng

Bắt đầu từ phiên bản Junos OS 17.2R1, PBB được tích hợp với EVPN nhằm giảm đáng kể quá trình học tập MAC trong control plane của mạng core. Điều này cho phép hỗ trợ một số lượng lớn dịch vụ lớp 2 (Layer 2), chẳng hạn như kết nối trung tâm dữ liệu, với thiết kế mạng đơn giản hơn.

Trong mô hình PBB-EVPN, thiết bị Backbone Core Bridge (BCB) trong lõi PBB được thay thế bằng mạng MPLS, trong khi vẫn giữ lại khả năng mở rộng dịch vụ nhờ vào thiết bị Backbone Edge Bridge (BEB). Thành phần B (hay provider routing instance) sẽ được quảng bá qua BGP bằng signaling EVPN và được đóng gói bên trong MPLS thông qua các thiết bị PE và P. Tóm lại, PBB-EVPN kết hợp khả năng mở rộng vượt trội của PBB với sự đơn giản của mạng MPLS truyền thống, giúp giảm đáng kể lượng trạng thái cần duy trì trong toàn mạng — điều mà EVPN thuần túy không làm được.

Hình 1: PBB với Multihoming EVPN ở chế độ Active/Standby

Trong Hình 1, PBB được tích hợp với EVPN, nơi các thiết bị CE được cấu hình multihomed theo chế độ Active/Standby.
Thiết bị CE1 được multihomed đến các thiết bị PE1, PE2 và PE3, trong khi thiết bị CE2 được multihomed đến các thiết bị PE3 và PE4.

Cấu hình

Cấu hình nhanh bằng CLI (CLI Quick Configuration)

Để cấu hình nhanh ví dụ này, hãy thực hiện các bước sau: Sao chép các lệnh sau đây và dán vào một tệp văn bản. Xóa các ngắt dòng nếu cần. Chỉnh sửa thông tin phù hợp với cấu hình mạng thực tế của bạn (ví dụ: tên interface, địa chỉ IP, ASN...). Sao chép và dán toàn bộ lệnh vào CLI tại cấp độ [edit]. Sau đó, nhập lệnh commit từ chế độ cấu hình để áp dụng.
