Multicast PIM on Nexus 9000

[Ali.Allafzadeh1]

Hi Everyone,
I have a problem with Sparse-mode multicast configuration in Nexus 9000. 

I have 2 VLANs (Vlan 2 and 3) and we want to send multicast traffic between VLANs. I have implemented multicast routing (Feature Pim). Stream Server is in VLAN 2 and Receiver is in VLAN3.

I configured Static-RP once but it didn't work and after that I tried Auto-RP but it didn't work either. Could you please check our configuration and let us know if it's the correct configuration? 
Just for info, the multicast inside the VLAN can work without any problem.
Here is my configuration for Static RP and Auto-RP, Can anyone tell me What is the problems? 

Static RP Confiugration:
feature pim
ip pim rp-address 10.2.2.2 group-list 239.0.0.0/8
ip pim ssm range none

interface vlan 2
ip pim sparse-mode
ip igmp version 3
!
interface vlan 3
ip pim sparse-mode
ip igmp version 3

Auto-RP Configuration:
feature pim
ip pim auto-rp rp-candidate Vlan2 group-list 239.0.0.0/8
ip pim auto-rp mapping-agent Vlan2
ip pim ssm range none
ip pim auto-rp forward listen

interface vlan 2
ip pim sparse-mode
ip igmp version 3
!
interface vlan 3
ip pim sparse-mode
ip igmp version 3

Many Thanks,
Ali

Couple of question, is the interface vlan 3 and vlan2 has IP configuration not seen any IP configured, can you post show interface vlan2 and 3 to undertand

config looks ok for me to start with.,

Please also post below information

show run interface vlan 2

show run interface vlan 3

show ip pim interface

show ip pim group-range

THe Stream Server is in VLAN 2 with IP 192.168.2.100 and gatway 192.168.2.1 and Stream receiver is in VLAN 3 with ip 192.168.3.100 and gateway 192.168.3.1

Hello @Ali.Allafzadeh1 ,

you need igmp version 2 on SVI interfaces

igmp version 3 is for SSM and you have configured

>>>ip pim ssm range none

For the RP you can use a loopback interface

Hope to help

Giuseppe

[Ali.Allafzadeh1]

I have tested also with igmp version 2 but unfortunately it does not work 

[Ali.Allafzadeh1]

also I have tested with vlan IP for RP and also loopback IP for RP but it does not work! 

[balaji.bandi]

Can you post the config and output after changing to IGMP v2

What's the fix? Did anybody figure this out?
