10 (Optional) On the IPv6 settings page, select an option for obtaining IPv6 addresses.
Option Description
Obtain IPv6 addresses automatically
through DHCP
Use DHCP to obtain IPv6 addresses. A DHCPv6 server must be present on the
network.
Obtain IPv6 addresses automatically
through Router Advertisement
Use router advertisement to obtain IPv6 addresses.
In ESXi 6.5 and later router advertisement is enabled by default and supports the
M and O flags in accordance with RFC 4861.
Static IPv6 addresses a Click Add IPv6 address to add a new IPv6 address.
b Enter the IPv6 address and subnet prefix length, and click OK.
c To change the VMkernel default gateway, click Override default gateway for
this adapter.
The VMkernel Default Gateway address for IPv6 is obtained from the selected
TCP/IP stack.
11 Review your settings selections on the Ready to complete page and click Finish.
After you create a VMkernel adapter on the vMotion TCP/IP stack, you can use only this stack for vMotion
on this host. The VMkernel adapters on the default TCP/IP stack are disabled for the vMotion service. If a
live migration uses the default TCP/IP stack while you are configuring VMkernel adapters with the
vMotion TCP/IP stack, the migration completes successfully. However, the involved VMkernel adapters on
the default TCP/IP stack are disabled for future vMotion sessions.
What to do next
Assign a default gateway, and configure the DNS settings, congestion control, and maximum number of
connections for the vMotion TCP/IP stack. For more information on how to change the configuration of a
TCP/IP stack on a host, see the vSphere Networking documentation.
Place Trac for Cold Migration, Cloning, and Snapshots
on the Provisioning TCP/IP Stack
Use the provisioning TCP/IP stack to isolate traffic for cold migration, VM clones, and snapshots, and to
assign a dedicated default gateway, routing table, and DNS configuration for this traffic. To enable the
Provisioning TCP/IP stack, assign it a new VMkernel adapter.
By using a separate TCP/IP stack, you can handle vMotion and cold migration traffic according to the
topology of the network and as required for your organization:
n
Route the traffic for migration of powered on or powered off virtual machines by using a default
gateway. The gateway must be different from the gateway assigned to the default stack on the host.
By using a separate default gateway, you can use DHCP for IP address assignment to the VMkernel
adapters for migration in a flexible way.
n
Assign a separate set of buffers and sockets.
n
Avoid routing table conflicts that might otherwise appear when many features are using a common
TCP/IP stack.
