Multicast over VPLS link

‎04-18-2017 12:40 AM

Hello All,

 

Hoping to find some help here. I have 2 ex3300's switches connected together via VPLS. They are connected via VPLS because they are a few thousand miles apart.

 

I've enable PIM and IGMP snooping on both switches. Both switches see each other, I can ping across and PIM neighbor adjacencies are formed.

 

I turn on a multicast source on switch B but the multicast route does not show up on switch A. If I set a static group on both switches then then route shows up and I and join the group and watch the video.

 

But manually inputting the groups is not something I want to do and it's time consuming.  PIM should propgate the multicast route automagically yes?

 

What does this have to do with routing? Well I'm thinking maybe I'm missing something in my VPLS config? Here's my routing-instance config:

 

set routing-instances A_to_B_video_link instance-type vpls

set routing-instances A_to_B_video_link interface xe-0/0/1.1005

set routing-instances A_to_B_video_link protocols vpls interface xe-0/0/1.1005

set routing-instances A_to_B_video_link protocols vpls no-tunnel-services

set routing-instances A_to_B_video_link protocols vpls vpls-id 202

set routing-instances A_to_B_video_link protocols vpls neighbor xxx.xxx.xxx.xxx

 

Do I need to put any pim or igmp configurations in the routing instance? Let me know if you want to see the PIM stuff on the EX's. 

 

Any nuggets of info is greatly apprecated.

 

Thanks

Ben

Hello,

Is this PIM-SM or PIM-DM? Also, do You have IGMP enabled (in addition to "IGMP snooping")?

Do You have IGMP Join coming to switch from the device You are trying to watch the video on?

HTH

Thx
Alex

Please add the below command and check if it works:

 

set routing-instances A_to_B_video_link protocols pim-snooping

 

You can verify if it works by checking below commands:

 

show pim snooping neighbors detail 

 

-This will display two Ex switches as neighbors

 

show pim snooping statistics

 

- Displays pim control plane packets/message like Pim Join/Prune received .

 

You can check Below two commands  as well :

 

show pim snooping join extensive
 
show multicast snooping route extensive instance A_to_B_video_link group <x>

Hi Vincy,

 

Thanks for your suggeston. Unfortunally one of the PE's is running 10.4 and does not have pim-snooping avaialble, it only has igmp-snooping. It will be a while before i can schedule upgrading it. 

 

Still looking.

 

Thanks

Ben
