Relay destination address. There are two types of relay destination address:
•
•
Specifies the relay destination when the relay destination is in the global
address space and when the relay source is in a virtual routing and
forwarding (VRF) instance.
Specifies the VRF instance associated with the relay destination IPv6
address.
(Optional) Interface type and number that specifies the 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.
(Optional) Specifies the DHCPv6 link address. The link-address must be an
IPv6 globally scoped address configured on the network interface where the
DHCPv6 relay is operational.
(Optional) Specifies the network interface source address. The
source-address can be any IPv6 global-scoped address on a device.
Modification
This command was introduced on the Catalyst 4500 series switches in a release
prior to Cisco IOS Release 152(5)E2.
Link-scoped unicast or multicast IPv6 address. User must specify an
output interface for this kind of address.
Global or site-scoped unicast or multicast IPv6 address.
