DHCP relay agent for IPv6

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(config)# interface ethernet 2/3
BigIron(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.
BigIron RX#show ipv6 dhcp-relay
telnet@RX16-8120#sh
DHCPv6 relay agent RCV 0 packets,
telnet@RX16-8120#
Syntax: show ipv6 dhcp-relay
Enabling support for network-based ECMP load sharing for
IPv6
Network-based ECMP load sharing is supported. If this configuration is selected, traffic is
distributed across equal-cost paths based on the destination network address. Routes to each
network are stored in CAM and accessed when a path to a network is required. Because multiple
hosts are likely to reside on a network, this method uses fewer CAM entries than load sharing by
host. When you select network-based ECMP load sharing, you can choose either of the following
two CAM modes:
•
•

Displaying ECMP load-sharing information for IPv6

To display the status of ECMP load sharing for IPv6, enter the following command.

Dynamic Mode – In the dynamic mode, routes are entered into the CAM dynamically using a
flow-based scheme. In this mode routes are only added to the CAM as they are required. Once
routes are added to the CAM, they are subject to being aged-out when they are not in use.
Because this mode conserves CAM, it is useful for situations where CAM resources are
stressed or limited.
Static Mode – In the static mode, routes are entered into the CAM whenever they are
discovered. Routes are not aged once routes are added to the CAM and they are subject to
being aged-out when they are not in use.
