mld-router-show

Multicast Listener Discovery (MLD) is a Layer 3 multicast protocol used between IPv6 hosts and routers similar to how IGMP is used for IPv4. MLD snooping allows a switch to examine MLD packets and make forwarding decisions based on their content.

MLD snooping constrains IPv6 multicast traffic at Layer 2 by configuring Layer 2 LAN ports dynamically to forward IPv6 multicast traffic only to those ports that want to receive it.

If MLD Snooping is not configured, Netvisor forwards multicast traffic to all the switch ports, impacting switch performance.

Syntax   mld-router-show

node-ip ip-address

Specifies the name of the IP node for the MLD configuration.

vnet vnet-name

Specifies the name of the VNET assigned to the MLD configuration.

l2-net l2-net-name

Specifies the name of the Layer 2 network.

vlan vlan-id

Specifies the ID of the VLAN for the MLD configuration.

port port-number

Specifies the number of the port for the MLD configuration.

Defaults   None.

Access   CLI

History   

Version 2.3

Command introduced.

Version 2.4.1

The parameters, group-ip, source-ip, node-type, and expires, deprecated. The parameter, vnet, added.

Version 3.0.0

The parameter, l2-net, added.

Usage   Default behavior, when MLD Snooping is not configured, multicast traffic is forwarded to all the switch ports, impacting switch performance.

Examples  To display MLD router parameters for the local switch, use the following command:

CLI network-admin@switch > mld-router-show
