Use
ipv6 dhcp advertise address-route
to enable the DHCPv6 relay agent to advertise
host routes for IPv6 addresses assigned to DHCP clients.
Use
undo ipv6 dhcp advertise address-route
to disable the DHCPv6 relay agent from
advertising host routes for IPv6 addresses assigned to DHCPv6 clients.
Syntax
ipv6 dhcp advertise address-route

Usage guidelines
In a network where ND cannot resolve global unicast addresses, network devices cannot generate
ND entries for all global unicast addresses. If a DHCPv6 client obtains a global unicast address, the
neighboring devices do not have the ND entries for this global unicast address, thus cannot forward
the packets destined for the client. To resolve this problem, enable the DHCPv6 relay agent to
advertise host routes for assigned IPv6 addresses in DHCP replies. The advertised route information
is as follows:
•
The destination IP address is the assigned IPv6 address.
•
The next hop is the link-local address of the DHCPv6 client.
•
The output interface is the interface that forwards the reply.
After the relay agent receives a packet destined for the assigned IPv6 address, the relay agent looks
up the routing table for the next hop. ND resolution can succeed because the next hop is the
link-local address of the client. The relay agent searches the ND table for the MAC address of the
client based on the next hop and then forwards the packet.
Before using this command on the DHCPv6 relay agent, enable the DHCPv6 relay agent to record
DHCPv6 relay entries first.

# Enable the DHCPv6 relay agent to advertise host routes for IPv6 addresses assigned to DHCPv6
clients.
