IPv6 Support on Flex and Mesh

IPv6 Support on Flex + Mesh Deployment

IPv6 is the backhaul transport of the Service Provider. The IPv6 support over flex + mesh feature is now supported on the Cisco Catalyst 9800 Series Wireless Controller . WLAN accepts IPv6 clients and forward the traffic.

Configuring IPv6 Support for Flex + Mesh

Follow the procedure given below to enable the IPv6 routing on the controller :

Procedure

  Command or Action Purpose

Step 1

configure terminal

Example:

Device# configure terminal

Enters global configuration mode.

Step 2

interface vlan vlan-interface-number

Example:

Device(config)#interface vlan 89

Creates an interface and enters the interface configuration mode.

Step 3

shutdown

Example:

Device(config-if)#shutdown

Disables the interface configuration.

Step 4

ipv6 enable

Example:

Device(config-if)#ipv6 enable

Optional. Enables IPv6 on the interface.

Step 5

ipv6 address X:X:X:X::X/<0-128>

Example:

Device(config-if)#ipv6 address 1:1:1:1::1/64

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

Step 6

no shutdown

Example:

Device(config-if)#no shutdown

Enables the IPv6 address.

Step 7

no shutdown

Example:

Device(config-if)#no shutdown

Enables the PIM dense-mode operation.

Step 8

end

Example:

Device(config-if)#end

Returns to privileged EXEC mode.

Step 9

show ipv6 interface brief

Example:

Device#show ipv6 interface brief

Verifies your entries.

Step 10

ping ipv6 destination-address or hostname

Example:

Device#ping ipv6 1:1:1:1::10

Checks the gateway connectivity.

Configuring Preferred IP Address as IPv6 (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

From the Preferred Mode drop-down list, select IPV6.

Step 5

Click Update & Apply to Device.

Configuring Preferred IP Address as IPv6

Procedure

  Command or Action Purpose

Step 1

Configure Terminal

Example:

Device# configure terminal

Enters global configuration mode.

Step 2

ap profile default-ap-profile

Example:

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

Enters AP profile configuration mode.

Step 3

preferred-mode ipv6

Example:

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

Uses IPv6 to join the controller .

Step 4

end

Example:

Device(config-ap-profile)# end

Exits the configuration mode and returns to privileged EXEC mode.

Verifying IPv6 on Flex+Mesh

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

Device#show ip interface brief
