IPv6 multicast architecture
How UPMC site is accessing to the IPv6 multicast service for transmitting with DVTS ?
Logical path for IPv6 multicast from France to Asia The M6Bone network : (http://www.m6bone.net)
– What is the M6Bone ?• An IPv6 Multicast test network
• M6Bone started in July 2001 (Aristote association, G6 and RENATER)
• 28 networks & 50 sites
– Goals• To offer IPv6 Multicast connectivity to interested sites
• Test and develop soft and equipments related to IPv6 Multicast technologies
• Be active in IPv6 multicast standardization
• To deploy an advanced service on IPv6, in order to participate in the dissemination of the protocol
2018/04/06 SOI Asia/AI3 joint Meeting 2006’ Spring, 18-20 April, Hua Hin, Thailand
M6Bone Connectivity
– IPv6 multicast is deployed natively in more and more networks– Need to bypass the routers not supporting IPv6 multicast (IPv6-in-IPv6, IPv6-in-IPv4,
GRE tunnels) Topology routing
– MBGP– Static IPv6 multicast routes
PIM – multicast trees– PIM-SMv2 (requires MLDv1) and PIM-SSM (requires MLDv2)– Global RP in RENATER
Interdomain multicast– No MSDP available in IPv6– Embedded RP under deployment
Applications and services :– Every IPv6 stack supports MLD and few applications use MLDv2– Videoconferencing and diffusion : VIC/RAT, Videolan, DVTS, Isabel, WM player 9– Radio broadcast : Freeamp– Others : NTE, WB, MAD, SDR– Reflectors
Monitoring– Connectivity / Traffic : ping, SNMP– Routing : AS-Path-Tree– PIM – Multicast topology : beacon and dbeacon

DVTS tests and results on french side
UPMC : – DVTS Sender is connected to RAP by a VLAN (MLDv1, rtadvd)
RAP :– IPv6-in-IPv6 tunnel MTU between RAP and RENATER is configured at 1280 Bytes :
• No possible change
– In IPv6 multicast, pMTU implementation fails on some equipments or isn’t available :• Problem if packet > 1280 Bytes :
– Dropped by router because fragmentation should be made by the host using pMTU if necessary
• Adjusting of packets size to transmit by DVTS with DIF Block paremeter :– By default : DIF Block = 17, packet size = 1360 Bytes
– In our case : DIF Block = 14, packet size = 1120 Bytes
RENATER :– ipv6 mfib cef output enabled : reduction of M6Bone router’s CPU charge
After these adjustements : DVTS transmission OK!! It’s possible to increase tunnel MTU between RAP and RENATER by changing
the tunnel end-point on RAP side
