Configuring the Layer 2 Mode IPv6 Querier Address

You can configure an IPv6 querier address for every VLAN. This functionality is available only for multicast snooping.

In releases prior to FastIron 08.0.50, you could not specifically configure a querier address per VLAN. Instead, in an IPv6 environment, a system MAC-dependent link local address was used as a querier address.

Starting with FastIron release 08.0.50, you can configure a Layer 2 mode querier IP address. You can now plan an elected querier location suitable for your network and use the most suitable querier location. This address can be configured regardless of whether the current multicast snooping mode is set to active or passive. Once the mode changes to active, the configured IP address is used as a querier address. You can configure a different querier IP address for every VLAN.

  1. Enter global configuration mode.
    device# configure terminal
  2. Enter VLAN configuration mode.
    device(config)# vlan 100
  3. Enter the multicast6 querier-address command followed by the IPv6 address.
    device(config-vlan-100)# multicast6 querier-address FE80::44

The following example configures an IPv6 address as the multicast querier address for the VLAN.

device# configure terminal
device(config)# vlan 100
device(config-vlan-100)# multicast6 querier-address FE80::44
