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


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
