Multicast and Unified Access

ERS 8800/8600 switches support multicast with Avaya VENA Unified Access enabled. However, the
number of IP multicast streams that the switch supports depends on the Unified Access
configuration.
In an ERS 8800/8600 switch, each IP multicast stream has a corresponding IpmcPep record that
indicates the following information:
• multicast stream incoming VLAN
• multicast group ID (MGID)
• outgoing port list
The switch uses these records to forward multicast traffic. In an SMLT environment, two IpmcPep
records are required for each multicast stream to handle the multicast traffic coming from IST and
SMLT links respectively.
Multicast stream support with Remote VLANs
The number of multicast streams that a WSP can support depends on the number of Remote
VLANs on the WSP. The following sections describe a configuration with one Remote VLAN and
another configuration with two Remote VLANs.
Important:
Network administrators must understand how IpmcPep records are used and how they affect
the total number of multicast streams that their network can support.
