Model 1 Multicast Configuration
Let us configure a multicast service for model 1.
An STB, which works in VLAN 14, is connected to an ONT port in this example. Upstream IGMP packets
arrive at VLAN 14 though a GEM port and the OLT changes VLAN 14 to subscriber's VLAN 200.
As we have a multicast server in VLAN 98 in our example, we need to configure a proxy in switch to
translate IGMP packets from VLAN 200 to VLAN 98 (see 14.3). The multicast service comes downstream
to the ONT port in VLAN 98 and changes to VLAN 14.
For more details on general configuration principles of data communication channel refer to Chapter 20,
page 76.
Fig. 24.3. Model 1 Multicast
Step 1.
Specify ONT serial number in configuration.
LTP-8X# configure terminal
LTP-8X(config)# interface ont 0/0
LTP-8X(config)(if-ont-0/0)# serial ELTX01234567
LTP-8X(config)(if-ont-0/0)# exit
Step 2.
Assign a service model:
LTP-8X(config)# gpon olt model 1
Step 3.
Create a "UsIGMP" cross-connect profile to configure the service which will be used to send
IGMP requests upstream. Configure a bridged service and specify the bridged group (it equals 1 in our
example) the ONT port will be associated with. Specify U-VLAN 14:
LTP-8X(config)# profile cross-connenct UsIGMP
LTP-8X(config-cross-connect)("UsIGMP")# bridge
LTP-8X(config-cross-connect)("UsIGMP")# bridge group 1
LTP-8X(config-cross-connect)("UsIGMP")# user vid 14
LTP-8X(config-cross-connect)("UsIGMP")# do show profile cross-connect UsIGMP
