multicast-replication

Syntax

Hierarchy Level

Description

Configure the mode of multicast replication that helps to optimize multicast latency.

Note:

The multicast-replication statement is supported only on platforms with the enhanced-ip mode enabled.

Default

This statement is disabled by default.

Options

Note:

The ingress and local-latency-fairness options do not apply to EVPN configurations.

ingress

Complete ingress replication of the multicast data packets where all the egress Packet Forwarding Engines receive packets from the ingress Packet Forwarding Engines directly.

local-latency-fairness

Complete parallel replication of the multicast data packets.

evpn irb local-only

Enables IPv4 inter-VLAN multicast forwarding in an EVPN-VXLAN network with a collapsed IP fabric, which is also known as a edge-routed bridging overlay.

evpn irb local-remote

Enables IPv4 inter-VLAN multicast forwarding in an EVPN-VXLAN network with a two-layer IP fabric, which is also known as a centrally-routed bridging overlay.

Note:

Selective multicast forwarding is only supported with local-remote.

  • Default: evpn irb local-remote

smet-nexthop-limit smet-nexthop-limit

Configures a limit for the number of SMET next hops for selective multicast forwarding. SMET next hops is a list of outgoing interfaces used by a PE device in selectively replicating and forwarding multicast traffic. When this limit is reached, no new SMET next hop is created and the PE device will send the new multicast group traffic to all egress devices.

  • Range: 10,000 through 40,000

  • Default: 10,000

Required Privilege Level
