Multicast ERS with PIM and VSP

[EF]

Hi team,

In a legacy network of ERS with SMLT we connect a new devies with fabric and this is the topology:

ERS8600 are the default gateways for both VLANs, for multicast transmitters and for receivers, and have PIM activated in their interfaces.

Now we move the recivers to the fabric and extend the VLAN Y (receivers) with I-SID.

All services works fine (DHCP, DNS, navigation, email, etc...) except multicast.

In the VSP7700 and VSP EDGE I configured :

router isis
spbm 1 multicast enable
interface vlan Y
ip igmp proxy

But it doesnt work.

Any idea?

Regards

EF

Refer for configuration examples to the following solution

Hello,

Two solutions are possible, the first is dynamically, the second (of course) statically.

As in a PIM network and a SPBM network MCAST's are only forwarded to ports were MCAST GROUP membership is requested (IGMP), the MCAST streams are not automatically forwarded (learned) between the PIM and SPBM networks.

Dynamic solution:
To connect a PIM MCAST network to an SPBM network, SPB-PIM Gateway nodes are needed, this is described the "VOSS User Guide v9.0_UG - 2023-10.pdf" document, see above link.

Static solution:
The static solution requires to configure IGMP static group membership on the link(s) between the PIM network and the SPBM network, static membership configuration is also described in the manual.
