EVE-NG Diagram
สิ่งที่เราปรับปรุงในคราวนี้
1. ที่ BNG เปลี่ยนการใช้ Physical Loop เป็นการใช้
Port cross connect (PXC) คือการใช้แค่พอร์ทเดียวในการทำ Loop ประหยัดพอร์ทได้ 1 พอร์ท สามารถใช้แทน physical loop แบบเดิมได้เลย ถ้ามีคนไปดูหน้าการ์ด คงบอกว่าพอร์ทว่างมีไว้ทำไม
Pseudowire Port (PW-Port) คือการผูก physical port เข้ากับ vc-id ประหยัดได้ 2 พอร์ท ไม่ต้องใช้ Loop เลย แต่มีข้อเสียคือต้อง tag-vlan เข้ามาตั้งแต่ต้นทาง และ traffic ต้องเข้าออกทาง physical พอร์ทนี้เท่านั้น ประหยัดแต่ไม่ยืดหยุ่น
2. ทำ Primary/Secondary Radius โดย
PPPoE Radius Primary=Radius1 และ Secondary=Radius2
IPoE Radiuss Primary=Radius2 และ Secondary=Radius1
3. ใช้ Python Script สำหรับ PPPoE access-accept ในตัวอย่างนี้เอาไว้ปรับแต่ง message ที่คุยกับ Radius เพราะบางที Radius ก็ไม่ได้รับส่งด้วย Attribute ของ NOKIA
4. ใช้ Mikrotik Router ซึ่งเป็นเร้าเตอร์ที่บ้านผมเองในการทำ NAT ออกเน็ต แทนการใช้ NAT-PC
5. แบ่ง MPLS domain ออกเป็นส่วน คือส่วนที่รันด้วย OSPF กับ ISIS และ ปรับปรุง L2VPN Architecture ใหม่

NOKIA-AGG(10.10.10.3) คอนฟิก Infra-structure ด้วย OSPF, ISIS, MPLS LDP
ที่โหนดนี้ได้ทำ Redistribute System IP address จาก OSPF ไป ISIS เพื่อให้โหนดไซต์ Access เห็น การ Redistribute ควรระวังเรื่อง Routing Loop. ในตัวอย่างนี้ Huawei จะ learn NOKIA-AGG system(10.10.10.3) จาก OSPF และ ISIS แต่จะเลือก OSPF เป็น best route เพราะค่า Preference

3. ฝั่ง Core สำหรับ Internet และ Radius โดยใช้ BGP
ใช้ IP ขา Wan ในการทำ bgp peer.
BNG จะประกาศ loopback radius และประกาศ subscriber address ที่ track srrp state เพื่อใช้ในการควบคุมทราฟฟิกที่มาจาก Internet ให้ลงมาที่ BNG ที่สถานะเป็น Master เพื่อให้ทราฟฟิกขาขึ้นและขาลงจะได้เป็นทางเดียวกัน (symmetric route) ส่วนการคอนฟิก srrp, group-interface , subscriber-interface จะแสดงไว้ในส่วนของ BNG Subscriber management
Mikrotik เป็นอุปกรณ์จริงที่อยู่ที่บ้าน ทำหน้าเป็น NAT และทางออก Internet โดยจะประกาศ default-route ให้ vSRX

อาจใช้ winscp เพื่อ ftp file หรือ vi หรือ วิธีอื่นๆ ตามสะดวกนะครับ
Python นี้จะทำหน้าที่เปลี่ยนจาก reply message จาก radius ที่มาด้วยค่า SUB-PPPOE-10M|SLA-PPPOE-10M จากนั้นก็แยก sub profile กับ sla profile ออกกันด้วยเครื่องหมาย "|" แล้วเซ็ตค่านั้นให้ให้กับ BNG เลย
file location: cf3:\python-script\cotton_accept.py
# Cotton NOKIA Radius python script
from alc import radius
# reply_msg = "SUB-PPPOE-10M|SLA-PPPOE-10M"
if radius.attributes.isSet(18):
print "REPLY_MSG = ", radius.attributes.get(18)
reply_msg = radius.attributes.get(18).split("|")
if len(reply_msg) == 2:
sub_profile = reply_msg[0]
sla_profile = reply_msg[1]
radius.attributes.setVSA(6527, 12, sub_profile)

Diagram สำหรับ SRRP และ Redundant interface
redundant interface เอาไว้สำหรับ รับส่งทราฟฟิกระหว่าง group-interface BNG1, BNG2 ในกรณ์ที่ ทราฟฟิกที่ลงมาจาก Internet มาเข้าที่ BNG (backup)
BNG (backup) จะส่งทราฟฟิกให้ BNG(master) ผ่านทาง redundant interface ก่อน
จากนั้น BNG master ค่อยส่งทราฟฟิกไปให้ subscriber user
แต่ในแล็บนี้ Redundant ในภาวะปกติจะไม่ได้ใช้งาน เพราะเรา control traffic ให้ลงตัว Master เท่านั้นด้วยการ track srrp

PPPoE message path ใช้ pw-1:11 โดย pw-1 คอนฟิกได้ที่ BNG1 sdp 103, BNG2 sdp 204 โดยผูกกับ port 1/1/2 vc-id 110 ในที่นี้ design ให้ srrp ใช้ vc-id เดียวกันกับทราฟฟิก และให้วิ่งผ่าน NOKIA-AGG vpls 110 และ Huawei vsi id 110 ที่ BNG จะไม่มีคอนฟิก epipe หรือ vpls เพิ่ม

สำหรับ PPPoE sync-lost ที่ BNG2 ผมยังไม่รู้ว่าปัญหาอยู่ที่ใหน ถ้าแก้ได้หรือรู้ว่าอยู่ตรงใหนผมจะกลับมาอัพเดทอีกทีครับ ตอนนี้ show log ไว้ก่อนละกัน
สิ่งที่ลองเทสแก้ปัญหาไปแล้วคือ เปลี่ยนตัว Master ก็ยัง sync-lost , เพิ่ม physical Link BNG1-BNG2 ก็ยัง sync-lost และลองคอมมานอื่นๆ ก็ยังไม่ได้ เลยไม่แน่ใจว่าเป็นเพราะลองในแล็บหรือป่าว ถ้ามีโอกาสผมจะลองเอาคอนฟิกชุดนี้ใช้กับอุปกรณ์จริงแล้วมาเล่าให้ฟังครับ

แล็บนี้ไม่ใช่ดีไซน์ที่ดีที่สุด เพียงแต่อยากนำเสนอวิธีการคอนฟิกพื้นฐาน ความหลายของ solution และ อุปกร์ที่ใช้ครับ สำหรับแล็บ BNG ผมคงหยุดไว้เพียงเท่านี้ รอบหน้าอาจเจอกันที่ MPLS L3VPN, HoVPN และ RSVP-TE ครับ
