SPBM MULTICAST BETWEEN TWO FABRIC

[EF]

Hi Team,

I want to configure multicast between two fabric linked by legacy trunk of VLANs, they are two different fabrics not a multiarea fabric.

It´s multicast at L2, igmp snooping , the senders and receivers will be in both fabric distributed aleatory.

Is this topology supported? Any tips to configure it?

For ip igmp snooping inside a single fabric I configure:

At global level:

router isis
spbm 1 multicast enable

At VLAN level:

interface vlan XX
ip igmp proxy
ip igmp snooping

But I dont know how to inyect multicast traffic between them.

Regards

Thanks WillyHe,

but one question, and sorry in advance for my lack of knowledge. I understand PIM is used for multicast in L3 topologies and in this solution all members (senders and recivers) are in the same VLAN, or SPBM-PIM Gateway can acts in L2 topology?

Hi,

yes it works with statics groups, I was using the command incorrectly, GTAC give the solution, for example for 5 groups:

int vlan 200
ip igmp static-group 234.5.6.10 234.5.6.10 1/27 static
ip igmp static-group 234.5.6.11 234.5.6.11 1/27 static
ip igmp static-group 234.5.6.12 234.5.6.12 1/27 static
ip igmp static-group 234.5.6.13 234.5.6.13 1/27 static
ip igmp static-group 234.5.6.14 234.5.6.14 1/27 static
exit
