Configuring IPv6 Discovery in Gaia Clish

Important - In a Cluster Two or more Security Gateways that work together in a redundant configuration - High Availability, or Load Sharing., you must configure all the Cluster Members in the same way.

To see the available "set" commands for IPv6 Discovery, enter in Gaia Clish The name of the default command line shell in Check Point Gaia operating system. This is a restricted shell (role-based administration controls the number of commands available in the shell).:

set ipv6 rdisc6[Esc][Esc]

To see the available "show" commands for IPv6 Discovery, enter in Gaia Check Point security operating system that combines the strengths of both SecurePlatform and IPSO operating systems. Clish:

show ipv6 rdisc6[Esc][Esc]

Parameters

Parameter	Description
`interface <Name of Interface>`	Specifies the name of the interface, on which to run IPv6 Router Discovery.
`interface <Name of Interface> {off \| on}`	Disables (`off`) or enables (`on`) the ICMPv6 Router Discovery on the specified interface. Range: `off`, or `on` Default: `on`
`address <IPv6 address>`	Optional. Configures the IPv6 address prefix, for which to configure advertisement options.
`address <IPv6 address> autonomous {off \| on}`	Disables (`off`) or enables (`on`) the use of the specified address prefix by ICMPv6 Router Discovery clients for autonomous address configuration. Range: `off`, or `on` Default: `on`
`address <IPv6 address> default`	Resets IPv6 Router Discovery configuration for the specified address to default. This can be useful when interface addresses have changed, because it removes all configuration for the specified address from the database.
`address <IPv6 address> on-link {off \| on}`	Disables (`off`) or enables (`on`) the specified IPv6 address prefix on the link. Range: `off`, or `on` Default: `on`
`address <IPv6 address> prefix-pref-lifetime {<0-4294967295> \| default}`	Configures the preferred lifetime of the specified IPv6 address prefix. This value is placed in the Preferred Lifetime field in the Prefix Information option in Router Advertisements. It conveys how long IPv6 addresses generated from the specified IPv6 address prefix through stateless address autoconfiguration should stay preferred. (Stateless address autoconfiguration is the mechanism used by ICMPv6 Router Discovery protocol, as opposed to stateful address autoconfiguration provided by DHCPv6.) That means the node can use the IPv6 address in existing connections, but it is not valid for new connections. This value must not be greater than the configured `prefix-valid-lifetime`. For more information, see RFC 4862. The designated value of 4294967295 represents infinity. Range: 0-4294967295 seconds Default: 604800 seconds (7 days)
`address <IPv6 address> prefix-valid-lifetime {<0-4294967295> \| default}`	Configures the lifetime of the specified IPv6 address prefix for on-link determination. This value is placed in the Valid Lifetime field in the Prefix Information option. This value must not be less than the configured `prefix-pref-lifetime`. The designated value of 4294967295 represents infinity. Range: 0-4294967295 seconds Default: 2592000 seconds (30 days)
`dnshost <FQDN> {off \| on}`	Optional. Disables (`off`) or enables (`on`) the recursive DNS domain hostname advertising. `<FQDN>` is the applicable fully qualified DNS hostname. When disabled, this configuration is removed from the database.
`dnshost <FQDN> dnshost-lifetime {<0-2147483647> \| default}`	Configures how long hosts should store the configured recursive DNS domain hostname. Range: from (`max-adv-interval`) to (2 x `max-adv-interval`) seconds Default: 1.5 * `max-adv-interval` seconds
`dnsserver <IPv6 Network Address> {off \| on}`	Optional. Disables (`off`) or enables (`on`) the recursive DNS server advertising. When disabled, its lifetime configuration is removed from the database.
`dnsserver <IPv6 address> dnsserver-lifetime {<0-2147483647> \| default}`	Configures how long hosts should store the configured recursive DNS server. Range: from (`max-adv-interval`) to (2 x `max-adv-interval`) seconds Default: 1.5 * `max-adv-interval` seconds
`hop-limit {<0-255> \| default}`	Optional. Configures the Cur Hop Limit field of the Router Advertisement message. This value is used by neighboring nodes as the Hop Count field of the IP header in outgoing IP packets. The value of 0 means it is unspecified by this router. Range: 0-255 Default: 64
`managed-config {off \| on}`	Optional. Disables (`off`) or enables (`on`) the stateful IP address autoconfiguration. Specifies whether to obtain global IPv6 addresses through DHCPv6 (as opposed to stateless address autoconfiguration provided by ICMPv6 Router Discovery). This option is placed in the Managed address configuration flag in the Router Advertisement message. Range: Selected, or Cleared Default: Cleared
`max-adv-interval {<4-1800> \| default}`	Optional. Configures the maximum time allowed between sending unsolicited multicast ICMPv6 Router Advertisements on this interface. Unsolicited Router Advertisements are not strictly periodic. The interval between two advertisements is randomized to decrease the probability of synchronization with the advertisements from other routers on the same links. When an unsolicited advertisement is sent, the timer is reset to a random value between the `min-adv-interval` and the `max-adv-interval`. Range: 4-1800 seconds Default: 600 seconds
`min-adv-interval {<3-1800> \| default}`	Optional. Configures the minimum time allowed between sending unsolicited multicast ICMPv6 Router Advertisements on this interface. Unsolicited Router Advertisements are not strictly periodic. The interval between two advertisements is randomized to decrease the probability of synchronization with the advertisements from other routers on the same links. When an unsolicited advertisement is sent, the timer is reset to a random value between the `min-adv-interval` and the `max-adv-interval`. Range: 3-1799 seconds Default: (Value of `max-adv-interval`) / 3 seconds
`other-config {off \| on}`	Optional. Disables (`off`) or enables (`on`) the stateful autoconfiguration to obtain other configuration information besides IP addresses. Stateful autoconfiguration is provided by DHCPv6, as opposed to stateless autoconfiguration provided by ICMPv6 Router Discovery. Examples of such information include information related to DNS, or information on other servers within the network. This option is placed in the Other configuration flag in the Router Advertisement message. Range: `off`, or `on` Default: `off`
`reachable-time {<0-3600000> \| default}`	Optional. Configures how long a node assumes a neighbor is reachable after having received a reachability confirmation. This value is used by the Neighbor Unreachability Detection. The reachable time is placed in the Reachable Time field in the Router Advertisement message. The value 0 means it is unspecified by this router. Range: 0-3600000 seconds Default: 0 seconds
`retransmit-timer {<0-2147483647> \| default}`	Optional. Configures the interval between retransmitted Neighbor Solicitation messages if the node does not receive a response. This value is used by address resolution and Neighbor Unreachability Detection. The retransmit timer is placed in the Retrans Timer field in the Router Advertisement message. The value 0 means it is unspecified by this router. Range: 0-2147483647 seconds Default: 0 seconds
`router-lifetime {<0-2147483647> \| default}`	Optional. Configures how long from receipt of a Router Advertisement message that a host considers this router to be valid. If the router lifetime expires with no refreshing Router Advertisement, the host stops using this router. The value is placed in the Router Lifetime field of the Router Advertisement message. A value of 0 means that the router is not used as a default router. Range: from `max-adv-interval` to 9000 seconds, or 0 seconds Default: 3 * (Value of `max-adv-interval`) seconds
`send-mtu {off \| on}`	Optional. Disables (`off`) or enables (`on`) the MTU options in Router Advertisement messages sent to neighboring nodes. Range: `off`, or `on` Default: `off`
