[j-nsp] Multicast Traffic over L2VPN

[Paul Stewart]

Hi Harry and thanks for the posting.

We converted the path from a routing-instance type of L2VPN to that of VPLS
and now things are working fine.  I read through some RFC docs etc to try
and better  understand why that made it work - came up with some reading
about VPLS multicast support that L2VPN didn't have and then my head hurt
trying to understand it LOL ;)

Thanks,

Paul

Yes, I believe for L2 mcast should just work. This assumes the mcast is not
using some reserved MAC value such as that used by spanning tree, which if
not in a L2 port mode might be consumed locally, rather than transported to
the far end. 

Perhaps post your config (more than one type of l2 service, vpls vs. l2 ckt,
for example) and folks can comment.

Hi there..

 

I'm confused about something and wanted to ask the list for help..;)

 

Is there anything special required to carry multicast traffic across a L2VPN
path?  We have a situation where multicast isn't working properly and
there's a L2VPN path in the middle.  I have found lots of documentation on
layer 3 VPN's in Juniper and all the steps involved to bring that up . but
with a layer2 VPN does this not just pass through?

 

Sorry if this seems like a basic question - my love for multicast is pretty
limited.

 

Paul
