Inter-VLAN Multicast Routing on NEXUS 3000 Series

Hyunho Cho
Level 1
Level 1

Hello, I bought nexus 3064-T switch for studying of copper-based 10G ethernet deployment recently.

There are five VLANs in a switch - VLAN 1(default), VLAN 10, VLAN 20, VLAN 30 and VLAN 40

and assigned every ports to VLAN 10 ~ 40,

There's no physical router so I configured "IGMP snooping querier & IGMP snooping" for each VLAN

and so IGMP snooping works well in each VLAN (multicast traffic well pruned except for interested ports)

Inter-VLAN unicast routing is also OK!

But inter-VLAN multicast routing is not working at all.

 

in global configuration,

"feature pim" is already added

and in each interface (VLAN 10~40)

"ip pim sparse-mode" is also added.

 

Should I do additional config?

For example RP(Rendezvous Point) should be added for each VLAN? Where is the RP in this case?

What am I suppose to do for inter-VLAN multicast routing?

Please, Help me!!
