Configuring A Dhcpv6 Relay Address Pool; Specifying A Gateway Address For Dhcpv6 Clients - HPE FlexNetwork HSR6800 Configuration Manual

Configuring a DHCPv6 relay address pool

This feature allows DHCPv6 clients of the same type to obtain IPv6 addresses and other
configuration parameters from the DHCPv6 servers specified in the matching relay 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 address for
clients matching the same relay address pool.
Upon receiving a DHCPv6 Solicit or Request from a client that matches a relay address pool, the
relay agent processes the packet as follows:
•
Fills the link-address field of the packet with the specified gateway address.
•
Forwards the packet to all DHCPv6 servers in the matching relay address pool.
The DHCPv6 servers select an address pool according to the gateway address.
To configure a DHCPv6 relay address pool:
Step
1. Enter system view.
2. Create a DHCPv6 relay
address pool and enter its
view.
3. Specify gateway addresses
for the clients matching the
relay address pool.
4. Specify DHCPv6 servers
for the relay 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:
Step
1. Enter system view.
Command

Remarks
N/A
By default, no DHCPv6 relay
address pools exist.
This command is the same for
creating DHCPv6 address pools on
a DHCPv6 server. However, the
relay address pool name is not
necessarily the same as the server
address pool name.
By default, no gateway address is
specified.
You can specify a maximum of eight
gateway addresses, but only the first
one takes effect.
By default, no DHCPv6 server is
specified for the relay address pool.
You can specify a maximum of eight
DHCPv6 servers for one relay
address pool for high availability.
The relay agent forwards DHCPv6
Solicit and Request packets to all
DHCPv6 servers in the relay
address pool.
