IPv6 ready logo support for clusters

Last published : Sep 24, 2026
You can test clustered appliances for IPv6 Ready Logo certification. Modified commands for testing IPv6 core protocols, such as for ND test cases, Router Solicitation processing, and sending route advertisement and router redirection messages are available in a clustered setup. Following are the IPv6 functionalities available for testing the IPv6 core protocols.
Following are the modified functionalities available to pass IPv6 core protocols, such as ND test cases, Router Solicitation processing and sending Route advertisement and router redirection messaging in the IPv6readylogo phase2 test suite.
  • Link Local SNIPs
  • Address Resolution and Neighbor Unreachability
  • Router and Prefix Discovery
  • Router Redirection
  • DoDAD
With these modified commands, the following configurations are supported in a clustered appliance.

Supportable configurations for testing IPv6 core protocols

For a clustered setup to pass IPv6 Ready Logo test cases, you can run the following configurations on the Cluster Management IP address (CLIP).
  • global IP6 configuration
  • basic IPv6 configuration
  • more IPv6 configurations

Global configuration

A global IPv6 configuration enables you to set the global IPv6 parameters (such as relearning, routeRedirection, ndBasereachTime, nRetransmissionTime, natprefix, td, and doodad) to run the basic IPv6 configuration.
At the command prompt, type the following:
set ipv6 [-ralearning ( ENABLED | DISABLED )] [-routerRedirection (ENABLED | DISABLED )] [-ndBasereachTime<positive_integer>][-ndRetransmissionTime <positive_integer>] [-natprefix <ipv6_addr|*>[-td<positive_integer>]] [-doDAD ( ENABLED | DISABLED )]

Basic IPv6 configuration

The basic IPv6 configuration enables you to create an IPv6 address and bind to a VLAN interface. You can perform the following configurations to test the IPv6 core protocols.
To add a VLAN to the clustered setup by using the CLI
At the command prompt, type:
add vlan <id>
To add another VLAN to the clustered setup by using the CLI
At the command prompt, type:
add vlan <id>
To bind an interface to a VLAN by using the CLI
At the command prompt, type:
bind vlan <id> -ifnum <interface_name>
To bind an interface to a VLAN by using the CLI
This command adds the global prefix as on-link prefix into RA information for subsequent Router Advertisements. At the command prompt, type:
bind vlan <id> -ifnum <interface_name>
To add the IPv6 SNIP address on a VLAN by using the CLI
At the command prompt, type the following:
add ns ip6 <IPv6Address>@ [-scope ( global | link-local )][-type <type>
To add the IPv6 address on VLAN by using the CLI
At the command prompt, type the following:
add ns ip6 <IPv6Address>@ [-scope ( global | link-local )][-type <type>
To bind IPv6 address to VLAN by using the CLI
At the command prompt, type the following:
bind vlan &lt;id> [-ifnum &lt;interface_name> [-tagged]][-IPAddress <ip_addr|ipv6_addr|
To bind the IPv6 address to VLAN by using the CLI
At the command prompt, type the following:
bind vlan &lt;id> [-ifnum &lt;interface_name> [-tagged]][-IPAddress <ip_addr|ipv6_addr|
To display the link local IPv6 address attached to VLAN by using the CLI
At the command prompt, type the following:
sh VLAN

Example 1

add vlan 2
add vlan 3
bind vlan 2 -ifnum 1/2
bind vlan 3 -ifnum 1/3
add ip6 fe80::9404:60ff:fedd:a464/64 -vlan 2 -scope link-local -type SNIP
add ip6 fe80::c0ee:7bff:fede:263f/64 -vlan 3 -scope link-local -type SNIP
add ip6 3ffe:501:ffff:100:9404:60ff:fedd:a464/64 -vlan 2
add ip6 3ffe:501:ffff:101:c0ee:7bff:fede:263f/64 -vlan 3
bind vlan 2 -ipAddress 3ffe:501:ffff:100:9404:60ff:fedd:a464/64
bind vlan 3 -ipAddress 3ffe:501:ffff:101:c0ee:7bff:fede:263f/64

Example 2

sh vlan
1)      VLAN ID: 2      VLAN Alias Name:
        Interfaces : 1/6
        IPs :
             3ffe:501:ffff:100:2e0:edff:fe15:ea2a/64
3)      VLAN ID: 3      VLAN Alias Name:
        Link-local IPv6 addr: fe80::9404:60ff:fedd:a464/64
        Interfaces : 1/5
        IPs :
             3ffe:501:ffff:101:2e0:edff:fe15:ea2b/64
 Done

More IPv6 cluster configuration

To test IPv6 core protocols, you can use the following new or modified IPv6 configurations.
To set VLAN specific Router Advertisement parameters by using the CLI
At the command prompt, type:
set nd6RAvariables -vlan &lt;positive_integer> [-ceaseRouterAdv ( YES | NO)] [-sendRouterAdv ( YES | NO )] [-srcLinkLayerAddrOption ( YES | NO )][-onlyUnicastRtAdvResponse ( YES | NO )] [-managedAddrConfig ( YES | NO)] [-otherAddrConfig ( YES | NO )] [-currHopLimit &lt;positive_integer>][-maxRtAdvInterval &lt;positive_integer>] [-minRtAdvInterval&lt;positive_integer>] [-linkMTU &lt;positive_integer>] [-reachableTime&lt;positive_integer>] [-retransTime &lt;positive_integer>] [-defaultLifeTime&lt;integer>]
