DHCP relay agent for IPv6
44
Syntax: [no] ipv6 load-sharing [ | default-route]
This command enables host-based ECMP load sharing on the device. The command also disables
network-based ECMP load-sharing at the same time.
DHCP relay agent for IPv6
A client locates a DHCP server using a reserve, link-scoped multicast address. For this reason, it is
a requirement for direct communication between the client and the server that they be attached by
the same link. However, in some situations in which ease of management, economy, and scalability
is a concern, it is useful to allow a DHCP client to send a message to a DHCP server by using a
DHCP relay agent. A DHCP relay agent, which may reside on the clients link, is used to relay
messages between the client and the server. A DHCP relay agent is transparent to the client.
When the relay agent receives a message to be relayed from a client to another relay agent, it
creates a new Relay-forward message, puts the original DHCP message to relay forward option, and
includes its only address and the address it received is in the same option.
Configuring DHCP for IPv6 relay agent
You can enable the DHCP for IPv6 relay agent function and specify the relay destination addresses
on an interface by entering the command at the interface level.
BigIron RX(config)# interface ethernet 2/3
BigIron RX(config-if-e10000-2/3)#ipv6 dhcp-relay-dest 2001::2
Syntax: ipv6 dhcp-relay-dest < ipv6-address >
Select the ipv6-address to specify a destination address to which the client messages are
forwarded and enables DHCP for IPv6 relay services on the interface.
Displaying DHCP relay information
Use the show ipv6 dhcp-relay command to determine what DHCP relay agent packets have been
received or transmitted on the device.
Syntax: show ipv6 dhcp-relay
BigIron RX#show ipv6 dhcp-relay
telnet@RX16-8120#sh ipv6 dhcp-relay
DHCPv6 relay agent RCV 0 packets, TX 0 packets
telnet@RX16-8120#
