Configuring DHCPv6 in Gaia Portal

Step

Instructions

1

Open Gaia Portal and do the steps below.

2

 In the Network Management section, click the DHCPv6 page.

3

 In the DHCPv6 Server Subnet Configuration section, configure the applicable subnet from which to assign IPv6 addresses to network hosts:

3A

Click Add.

3B

At the top, select Enable DHCPv6 Subnet.

Next, configure the applicable settings on the Subnet tab.

3C

In the IPv6 address field, enter the IPv6 address of the subnet from which Gaia OS assigns IPv6 addresses to network hosts.

In the Mask length field, enter the applicable IPv6 mask length.

Note - To automate the process, click Get from interface, select the applicable interface, and then click OK to confirm your selection.

3D

Optional:

In the Address Pool section, configure the applicable IPv6 address pools from which Gaia OS assigns these IPv6 addresses to network hosts:

  1. Click Add.

  2. In the Type field, select Include or Exclude.

    This specifies whether to include or exclude this range of IPv6 addresses in the IPv6 address pool.

  3. In the Status field, select Enable or Disable.

    This enables or disables the DHCPv6 Server for this subnet, or the DHCPv6 Server process (depending on the context).

  4. In the Start field, enter the first IPv6 address of the range.

  5. In the End field, enter the last IPv6 address of the range.

  6. Click OK.

3E

Optional:

In the Lease Configuration section, configure the applicable lease time:

  1. In the Default lease field, enter the default lease time for all addresses in this IPv6 subnet.

    This applies only if DHCPv6 clients do not request a unique lease time.

    The default value in this field is 43,00 seconds.

    Valid values in this field are from 1 to the Maximum lease time.

  2. In the Maximum lease field, enter the maximum lease time for all address in this IPv6 subnet.

    The default value in this field is 86,400 seconds.

    Valid values in this field are from 1 to 4,294,967,295 seconds.

3F

Optional:

On the DNS tab, define routing and DNS parameters for DHCP clients:

  • In the Domain Name field, enter the domain name for the DHCPv6 clients (for example, example.com).

  • In the Primary DNS Server field, enter the IPv6 address of the Primary DNSv6 server for the DHCPv6 clients.

  • In the Secondary DNS Server field, enter the IPv6 address of the Secondary DNSv6 server for the DHCPv6 clients (to use if the primary DNSv6 server does not respond).

  • In the Tertiary DNS Server field, enter the IPv6 address of the Tertiary DNSv6 server for the DHCPv6 clients (to use if the primary and secondary DNSv6 servers do not respond).

3G

Click OK at the bottom.

4

 In the DHCPv6 Server Configuration section, select Enable DHCPv6 Server and click Apply.

Step

Instructions

1

In the DHCPv6 Client Configuration section, configure how Gaia OS interfaces receive their IPv6 addresses and click Apply:

  • Normal - Receive IPv6 address and configuration from a DHCPv6 server.

  • Prefix-delegation - Receive only IPv6 prefix from a compatible DHCPv6 server.

Note - Router discovery is automatically configured for the users.

2

Note - This step applies only if you select Prefix-delegation in step 1 above.

In the DHCPv6 Prefix-Delegation Configuration section, configure the applicable DHCPv6 Prefix settings:

2A

In the DHCPv6 Prefix-Delegation Requesting Interface section, leave the default option as None or select the applicable interface.

2B

In the DHCPv6 Prefix-Delegation Method section, select the applicable option:

  • Manual - Only calculate IPv6 addresses from the prefix and assign them to the interfaces configured to receive IPv6 through Prefix-Delegation.

  • Router Discovery - In addition to IPv6, automatically configure Router Discovery protocol on the configured interfaces.

  • DHCPv6 - In addition to IPv6, automatically configure the DHCPv6 Server feature on the new subnets and configure the Router Discovery protocol with the "Managed Configuration" flag on.

2C

In the DHCPv6 Prefix-Delegation - Suffix Pools for DHCPv6 Server Method section, configure the IPv6 address pools.

  1. Click Add.

  2. In the Type field, select Include or Exclude.

    This specifies whether to include or exclude this range of IPv6 addresses in the IPv6 address pool.

  3. In the Start field, enter the first IPv6 address of the range.

  4. In the End field, enter the last IPv6 address of the range.

  5. Click OK.

At the bottom of the page, click Apply.
