PIMD on 2.7.2-Release does not route multicast - IGMP Snooping Checksum error

viren_d_patel0

I am new to Multicasting.

Multicasting work on IGMP3 switch without PIMD.

I want to try to route Multicasting but no success.

I did try LAN and OPT interface and only LAN interface in both case same error in switch

I did check Packet capture through Wireshark and verify packet checksum error. Switch Log is reporting same error.

Switch Error log.
Sep 07, 2024, 12:30:26 Notice MCAST-5-PKT_CHKSUM_DROP: Received IGMP snooping checksum error: VLAN 1, interface Ethernet1/0/24(merged 1)

Any help highly appreciated.

How are you testing this? What are you using to generate or receive traffic? What errors do you see there?

I did use VLC steaming.

@stephenw10

On VLC receiver side not video.

Ok What do you see logged?

Do you see states opened for traffic?

Setting is simple

WAN - Router - LAN ---- IGMPv3 Switch --- comp1
|-- comp2

Only one interface LAN enabled.

Here is the Log from PIMD.

Let me know I am doing testing right way.

So the server is comp2 in the WAN subnet and the client in comp1 in the LAN subnet?

The switch is a layer 2 device?

viren_d_patel0

@stephenw10

No it is connected on LAN. I try to draw but did not post it right.

viren_d_patel0

@stephenw10
yes

viren_d_patel0

@stephenw10
Grand stream GWN7803

stephenw10

Hmm both test machines are connected to LAN? They are both in the LAN subnet?

viren_d_patel0

@stephenw10
yes

stephenw10

Hmm, then they should be able to talk directly. That traffic does not go through pfSense so pimd wouldn't be doing anything.

@stephenw10

Following test is with SINGLE LAN port.

Grandstream switch has IGMP V3. If you enable that it talks to router and supposed to connect based on IGMP reports. ( If router disabled PIMD switch control wiht out any problem )

It does work for few mins on single LAN connect but after few mins it gives error in Switch and Switch stop ccontrolling IGMP v3 trafic on that port with error.

My PC1 send multicast (SSM) three video 232.1.1.30 / 31 /32. PC2 receive no problem but after few sec it stops working.
