• rapid-commit — Is an option that allows for an abbreviated exchange
between the client and server.
• pref-value — Preference value — used by clients to determine preference
between multiple DHCPv6 servers. (Range: 0-4294967295)
Default Configuration
The default preference value is 20. Rapid commit is not enabled by default.
Command Mode
Interface Configuration (VLAN, Tunnel) mode
User Guidelines
An IP interface (VLAN) can be configured in DHCP relay mode or DHCP
server mode. Configuring an interface in DHCP server mode overwrites the
DHCP relay mode configuration and vice-versa.
An interface in server mode cannot be configured as a DHCP client (ip
address dhcp).
Example
The following example configures DHCPv6 server functionality.
console(config)#interface vlan 15
console(config-if-vlan15)#ipv6 dhcp server pool
prefix-delegation
Use the prefix-delegation command in IPv6 DHCP Pool Configuration mode
to define multiple IPv6 prefixes within a pool for distributing to specific
DHCPv6 Prefix delegation clients.
Syntax
prefix-delegation ipv6-prefix/prefix-length client-DUID [name hostname ]
[valid-lifetime { valid-lifetime | infinite}] [preferred-lifetime { preferred-
lifetime | infinite}]
no prefix-delegation ipv6-prefix/prefix-length
