pd-unshare-only

Function

The pd-unshare-only command configures a delegation prefix pool for only DHCPv6 IA_PD prefix allocation.

The undo pd-unshare-only command cancels the configuration.

By default, a delegation prefix pool is used for DHCPv6 IA_PD prefix allocation and stateless address autoconfiguration in unshared mode.

This command is supported only on the NetEngine 8000 F1A.

Usage Guidelines

Usage Scenario

If the delegation prefix pools for ND prefix allocation need to be differentiated with the delegation prefix pools for DHCPv6 IA_PD prefix allocation on a device, run the **slaac-unshare-only ** command and the **pd-unshare-only ** command in the corresponding delegation prefix pools.

Configuration Impact

After the pd-unshare-only command is run for a delegation prefix pool, this prefix pool can be used only for DHCPv6 IA_PD prefix allocation and is preferred in DHCPv6 IA_PD prefix allocation.

Precautions

In VS mode, this command is supported only by the admin VS.

Multiple address pools can be configured in a domain, and the address pool with the highest priority is preferred. A remote prefix pool configured only for DHCPv6 prefix or address allocation has a priority over that without the preceding configuration.

Example

# Configure a delegation prefix pool for only DHCPv6 IA_PD prefix allocation.
