HiCoins as reward： 0 (problem unresolved)

Hello,

I have GPON MA6500T.
I want to send multicast from ONT via OLT to switch PIM.
Unfortunately, OLT blocks multicast and other packages work.
Is there any configuration that will enable multicast transmission

Thanks.

Hello, friend!

The MA6500T that you mentioned does not exist. It should be the MA5600T.

You can create a multicast group in the following ways:

1. Create a multicast VLAN and VLAN of the upstream PIM interface, and add the upstream port to the VLAN of the PIM interface.

a. Run the VLAN command to create a multicast VLAN and VLAN of the upstream PIM interface.

b.Run the port VLAN VLAN-list frameid/slotid portlist to add the upstream port to the VLAN of the PIM interface.

2. Enable the multicast function.

Run the multicast routing-enable command to enable multicast or run the multicast ipv6 routing-enable command to enable IPv6 multicast.

3.Set upstream multicast mode to PIM.

If PIM-SM is used in the upstream direction, run the multicast upstream-mode pim-sm command to set the upstream multicast exchange mode to PIM-SM.

If PIM-SSM is used in the upstream direction, run the multicast upstream-mode pim-ssm command to set the upstream multicast exchange mode to PIM-SSM.

4. Create the VLAN interface of the upstream PIM interface, configure the IP address of the Layer 3 interface, and enable PIM on this Layer 3 interface.

a. Run the interface vlanif command to create the VLAN interface of the upstream PIM interface.

b.Run the IP address or ipv6 address command to configure the IP addresses of the Layer 3 interface.

c.Run the pim sm or pim ipv6 sm command to enable PIM on the Layer 3 interface.

5. Create the multicast VLAN interface, configure the IP address of the Layer 3 interface, and enable multicast on this Layer 3 interface.

Run the interface vlanif command to create a multicast VLAN interface.

Run the IP address or ipv6 address command to configure the IP addresses of the Layer 3 interface.

Run the igmp enable command to enable multicast on the Layer 3 interface or run the mld enable command to enable Multicast Listener Discovery (MLD) on the Layer 3 interface.

6.(Optional) If PIM-SM is enabled in the upstream direction, static RPs need to be configured.

Run the tatic-rp command to configure static RPs.

7. Configure multicast programs.

Run the igmp program add command to configure a multicast program.

8. Configure multicast users.

Run the igmp user add command to configure a multicast user.

I hope this helps you.

Thanks!

I want multicast entering ONT to be transferred by OLT.
In the standard configuration this function is blocked.
I did this configuration but it doesn't work.

Hello Yogson！
The process of configuring multicast does not appear in your description.
You can refer to the following configuration examples:

Gateway ONT Network Scenario (GPON and 10G GPON Access)

Bridging + Voice ONT Network Scenario (GPON and 10G GPON Access)

If you cannot open the link, please leave your email address.

Thank you!
