Configuring A Dhcpv6 Address Pool On The Dhcpv6 Relay Agent; Specifying A Gateway Address For Dhcpv6 Clients - HPE FlexNetwork 10500 Series Configuration Manual

Step
3. Specify a padding mode for
the Interface-ID option.
Configuring a DHCPv6 address pool on the
DHCPv6 relay agent
This feature allows DHCPv6 clients of the same type to obtain IPv6 addresses, IPv6 prefixes, and
other configuration parameters from the DHCPv6 servers specified in the matching DHCPv6
address pool.
It applies to scenarios where the DHCPv6 relay agent connects to clients of the same access type
but classified into different types by their locations. In this case, the relay interface typically has no
IPv6 address configured. You can use the gateway-list command to specify the gateway addresses
for clients matching the same DHCPv6 address pool.
Upon receiving a DHCPv6 Solicit or Request from a client that matches a DHCPv6 address pool, the
relay agent processes the packet as follows:
•
Fills the link-address field of the packet with a specified gateway address.
•
Forwards the packet to all DHCPv6 servers in the matching DHCPv6 address pool.
The DHCPv6 servers select a DHCPv6 address pool according to the gateway address.
To configure a DHCPv6 address pool on the DHCPv6 relay agent:
Step
1. Enter system view.
2. Create a DHCPv6 address
pool and enter its view.
3. Specify gateway addresses
for the clients matching the
DHCPv6 address pool.
4. Specify DHCPv6 servers
for the DHCPv6 address
pool.

Specifying a gateway address for DHCPv6 clients

By default, the DHCPv6 relay agent fills the link-address field of DHCPv6 Solicit and Request
packets with the first IPv6 address of the relay interface. You can specify a gateway address on the
relay agent for DHCPv6 clients. The DHCPv6 relay agent uses the specified gateway address to fill
the link-address field of DHCPv6 Solicit and Request packets.
To specify a gateway address for DHCPv6 clients:
Command
ipv6 dhcp relay interface-id
{ bas | interface }
Command
system-view
ipv6 dhcp pool pool-name
gateway-list
ipv6-address&<1-8>
remote-server ipv6-address
[ interface interface-type
interface-number ]
210
Remarks
By default, the relay agent fills the
Interface-ID option with the interface
index of the interface.
Remarks
N/A
By default, no DHCPv6 address
pools exist.
By default, no gateway address is
specified.
By default, no DHCPv6 server is
specified for the DHCPv6 address
pool.
You can specify a maximum of eight
DHCPv6 servers for one DHCPv6
address pool for high availability.
The relay agent forwards DHCPv6
Solicit and Request packets to all
DHCPv6 servers in the DHCPv6
address pool.
