Configuring DHCPv6 Server and Relay Settings 1279
Configuring DHCPv6 Interface Information
Beginning in Privileged EXEC mode, use the following commands to
configure an interface as a DHCPv6 server or a DHCPv6 relay agent. The
server and relay functionality are mutually exclusive. In other words, a VLAN
routing interface can be configured as a DHCPv6 server or a DHCPv6 relay
agent, but not both.
Command Purpose
configure Enter Global Configuration mode.
interface {tunnel
tunnel-id
| vlan
vlan-id
}
Enter interface configuration mode for a tunnel or VLAN
routing interface to configure as a DHCPv6 relay agent.
ipv6 dhcp relay
{destination
relay-
address
[interface vlan
vlan-id
] | interface vlan
vlan-id
} [remote-id
{duid-ifid |
user-
defined-string
}]
Configure the interface for DHCPv6 relay functionality.
•
destination

address.
•
relay-address
— An IPv6 address of a DHCPv6 relay
server.
•
interface

relay interface number, or it can be specified as a user-
defined string.
