ipv6 dhcp relay destination

ipv6 dhcp relay destination IPV6-ADDRESS [VLAN-INTERFACE]
no ipv6 dhcp relay destination
Syntax Description
IPV6-ADDRESS
VLAN-INTERFACE
Default
Command Mode
Usage Guideline
CLI Reference Guide
These commands are used to enable or disable the DHCP relay function.
Relay destination address.
This argument must be in the form documented in RFC 2373 where the address
is specified in hexadecimal using 16-bit values between colons.
Relay to which VLAN-interface.
Valn-interface specifies output interface for a destination. If this argument is
configured, client messages are forwarded to the destination address through
the link to which the output interface is connected.
DHCP relay: Disabled
IPV6-ADDRESS: None
VLAN-INTERFACE: NULL.
Interface configuration
The ipv6 dhcp relay destination command specifies a destination address to
which client messages are forwarded and it enables DHCP for IPv6 relay service
on the interface. When relay service is enabled on an interface, a DHCP for IPv6
message received on that interface will be forwarded to all configured relay
destinations. The incoming DHCP for IPv6 message may have come from a
client on that interface, or it may have been relayed by another relay agent.
The relay destination can be a unicast address of a server or another relay
agent, or it may be a multicast address. The following are the two types of relay
destination addresses:
• A link-scoped unicast or multicast IPv6 address, for which, a user must
specify an output interface
• A global or site-scoped unicast or multicast IPv6 address, for which, a
user CANNOT specify the output interface. The output interface will
determined by routing table.
If no output interface is configured for a destination, the output interface is
determined by routing tables. In this case, it is recommended that a unicast or
multicast routing protocol be running on the router. Multiple destinations can be
configured on one interface, and multiple output interfaces can be configured for
one destination. When the relay agent relays messages to a multicast address, it
sets the hop limit field in the IPv6 packet header to 32.
