This article describes general information on IPv6 Support on MR access points. Please see IPv6 Device Compatibility documentation for more information on compatible devices.

Overview

This document describes the functionality, configuration, and caveats of the IPv6 feature set on MR access points.

Note: Only IPv6 functionality that is explicitly listed in this document is currently supported.

Note: The mandatory DHCP option (Wireless > Configure > Access Control) must be disabled for IPv6-only or dual-stack (IPv4/IPv6) clients connected to a Bridge mode SSID to have IPv6 connectivity.

Minimum Firmware Requirements

IPv6 support on MR access points was added in MR 28.1 firmware, with minimal IPv6 support in MR 27.X. Therefore, the minimum firmware for the IPv6 support on MR access points is MR 28.1. As new IPv6 features are developed, they might have different minimum firmware requirements. This document breaks down IPv6 MR features supported in specific MR firmware releases.

Note: Since most of the IPv6 features listed in this document are firmware-dependent and require MR 28.1 or newer firmware, We suggest that you create and modify your wireless Meraki networks to ensure that all APs can run MR 28.X firmware. For example, if you have an older AP in the network that cannot run MR 28 firmware, some features might not work. Please refer to Product Firmware Version Restrictions for details on maximum runnable firmware on MR access points.

Warning: If a network where any MR IPv6 features are configured (for example, Layer 3 IPv6 firewall rules) is downgraded to MR 27.X or older firmware, this might result in a loss of IPv6 configuration or functionality on MR access points.

MR 27.X and Older Firmware Releases

Wireless IPv6 Bridging

Network-wide > Configure > General > Wireless IPv6 Bridging has two options - Disabled and Enabled.

When set to “Enabled”, MR will pass IPv6 traffic to clients connected to a Bridge mode SSID, MR Tools like Ping and Traceroute will work for IPv6 traffic, and MR will be able to use its IPv6 management address to check-in to the Dashboard over an IPv6-only upstream network.

When set to “Disabled”, MR will not pass IPv6 traffic to clients connected to a Bridge mode SSID, and MR Tools like Ping and Traceroute will not work for IPv6 traffic. However, MR will be able to use IPv6 on the uplink for management and Meraki dashboard connectivity purposes.
