Configuration Procedure; Configuring Ipv6 Address Assignment - HP FlexNetwork MSR2003 Configuration Manual

Configuration procedure

To configure IPv6 prefix assignment:
Step
1. Enter system view.
2. (Optional.) Specify the
IPv6 prefixes excluded
from dynamic
assignment.
3. Create a prefix pool.
4. Create a DHCPv6
address pool and enter
its view.
5. Specify an IPv6 subnet
for dynamic
assignment.
6. Configure static prefix
assignment, dynamic
prefix assignment, or
both.

Configuring IPv6 address assignment

Use one of the following methods to configure IPv6 address assignment:
•
Configure a static IPv6 address binding in an address pool.
If you bind a DUID and an IAID to an IPv6 address, the DUID and IAID in a request must match
those in the binding before the DHCPv6 server can assign the IPv6 address to the requesting
client. If you only bind a DUID to an IPv6 address, the DUID in a request must match the DUID
in the binding before the DHCPv6 server can assign the IPv6 address to the requesting client.
•
Specify a subnet and address ranges in an address pool.
Non-temporary address assignment—The server selects addresses from the
non-temporary address range specified by the address range command. If no
non-temporary address range is specified, the server selects addresses on the subnet
specified by the network command.

Remarks
N/A
By default, no IPv6 prefixes in
the prefix pool are excluded from
dynamic assignment.
If the excluded IPv6 prefix is in a
static binding, the prefix still can
be assigned to the client.
To exclude multiple IPv6 prefix
ranges, repeat this step.
This step is required for dynamic
prefix assignment.
By default, no prefix pool is
configured.
By default, no DHCPv6 address
pool is configured.
By default, no IPv6 subnet is
specified for dynamic
assignment.
By default, static or dynamic
prefix assignment is not
configured for an address pool.
To add multiple static IPv6 prefix
bindings, use the static-bind
prefix command multiple times.
