IPv6 Support on Flex and Mesh

IPv6 support on FlexConnect + mesh deployment

A FlexConnect and mesh deployment is a wireless network configuration that

  • enables IPv6 as the primary backhaul transport for service provider

  • supports IPv6 clients connecting via WLANs on the Cisco Catalyst 9800 series wireless controller and Cisco Embedded Wireless controller on Catalyst APs, and

  • forwards IPv6 client traffic efficiently to the network core.

Configure IPv6 support for FlexConnect + Mesh (CLI)

Follow these steps to enable IPv6 routing and multicast features for FlexConnect and Mesh on a controller using commands.

Procedure

Step 1

Enter the global configuration mode.

Example:

Device# configure terminal

Step 2

Create an interface and enter the interface configuration mode.

Example:

Device(config)#interface vlan vlan-interface-number

Step 3

Disable the interface configuration.

Example:

Device(config-if)#shutdown

Step 4

(Optional) Enable IPv6 on the interface.

Example:

Device(config-if)#ipv6 enable

Step 5

Configure IPv6 address on the interface using the IPv6 prefix option.

Example:

Device(config-if)#ipv6 address X:X:X:X::X/<0-128>

Step 6

Enable the IPv6 address.

Example:

Device(config-if)#no shutdown

Step 7

Enable the PIM dense-mode operation.

Example:

Device(config-if)#no shutdown

Step 8

Return to the privileged EXEC mode.

Example:

Device(config-if)#end

Step 9

Verify your entries and check the gateway connectivity.

Example:

Device# show ipv6 interface brief
Device# ping ipv6 destination-address or hostname

Configure preferred IP address as IPv6 (GUI)

Set the preferred IP address mode to IPv6 for APs joining the controller using the GUI.

Procedure

Step 1

Choose Configuration > Tags & Profiles > AP Join.

Step 2

Click the AP Join Profile Name. The Edit AP Join Profile window is displayed.

Step 3

Choose CAPWAP > Advanced.

Step 4

Select IPV6 from the Preferred Mode drop-down list.

Step 5

Click Update & Apply to Device.

Configure preferred IP address as IPv6 (CLI)

Set the AP to use IPv6 as its preferred IP address when joining the controller using commands.

Procedure

  Command or Action Purpose

Step 1

Enter the global configuration mode.

Example:

Device# configure terminal

Step 2

Enter the AP profile configuration mode.

Example:

Device(config)# ap profile default-ap-profile

Step 3

Use IPv6 to join the controller .

Example:

Device(config-ap-profile)# preferred-mode ipv6

Step 4

Exit the configuration mode and return to the privileged EXEC mode.

Example:

Device(config-ap-profile)# end

Verify IPv6 on FlexConnect + Mesh

To verify the IPv6 configuration on the controller , use this show command: 

Device# show ip interface brief
