Usage Guidelines

The display dhcpv6 relay prefix-delegation command is used on DHCPv6 relay agents. This command displays routing information that DHCPv6 relay agents learn from DHCPv6 PD terminals, including the destination IPv6 address, next hop address, outbound interface, and protocol type of each route. You can also use this command to view DHCPv6 PD routing information forwarded by the DHCPv6 Relay.
