CASE:
Network - AR3200 - RE:Multicast support over DSVPN


HUAWEI ANSWERED:
RiskofSolution:Non-RiskOperation
We talked to R&D. We can not provide.


Why Not? You have solved split horizon issues over DSVPN, why not about PIM? Because of this issue instead using DSVPN, we have to create over hundred of thousands individual P2P GRE tunnels.
Thanks

Other well known vendors have solved this cavitie with solution of "pim nbma mode". The other problem is that, Huaweis answer is not explanatory. In Hub&Spoke topology where the problem is about PIM, they have to explained it well. Instead

This post was last edited by jumbox at 2018-12-24 12:01. I was expecting more explanation from huawei multicast support over DSVPN but they just said that we dont support. But I ve tested the stuation and find out hub<->spoke multicast stream bidirectionaly working fine. In additionaly spoke<->spoke multicast is not working meanning not supported. For testing i did used ping and along side NTP Multicast Mode to distribute ntp information entire network.

As a summary huawei does support multicast over DSVPN between hub and spokes but not spoke to spoke.
 
From now Case solved and closed. In the future expecting that huawei to solve and implement spoke to spoke multicast support.

Thanks for yor deep knowledge and sharing it with us dear HUAWEİ :(

Hi @jumbox
the static mGRE tunnel established between hub and spoke, the multicast stream bidirectionaly could work fine on such tunnel due to the GRE tunnel could carry multicast traffic. But for mGRE tunnel established between spoke and spoke, it's no longer a static mGRE instead of dynamic mGRE tunnel, so, I would be more inclined to the multicast cannot transceived on the dynamic mGRE tunnel rather than the horizon-split causing the multicast traffic discarded.
As you know, in DSVPN network, the traffic between two spoke sites are transceived on the temporary dynamic mGRE tunnel, they wouldn't be sent to hub site, so your explanation about the reason of multicast traffic discarded between two spoke sites are the horizon split might be incorrect.

Thanks for your explanation @chenhui. But This answer and explanation came out too late for me. Because of your support told us multicast is not supported over dsvpn, along the side we already deployed the network with p2p gre. However ive tested dsvpn supportion of multicast, and success.
Spoke-to-spoke doesnt work because there is no direct connection between spokes. So whenever L3 to L2 resolution happens it fails because spokes doesnt directly connected.

So we only needed to hub and spoke multicast of course it depends how you design Mapping Agent and Randevu Point..If you put both role on hub everything works fine...
take care
