Displaying the DHCPv6 Relay information for an interface
Enter the show ipv6 dhcp-relay interface command to display the DHCPv6 relay information for a specic interface.
device#show ipv6 dhcp-relay interface ethernet 1/2/3
DHCPv6 Relay Information for interface e 1/2/3:
Destinations:
Destination OutgoingInterface
2001::2 NA
fe80::224:38ff:febb:e3c0 e 1/2/5
Options:
Interface-Id: Yes
Syntax: show ipv6 dhcp-relay interface interface-type port-num
Specify the interface-type as ethernet interface, tunnel interface, or VE interface. Specify the port-num as the port number.
The following table describes the
elds from the output of the show ipv6 dhcp-relay interface command.
TABLE 42 DHCPv6 relay information for an interface
Field Description
DHCPv6 Relay Information for interface interface-type port-num The DHCPv6 relay information for the specic interface.
Destination The congured destination IPv6 address.
OutgoingInterface The interface on which the packet will be relayed if the destination relay
address is a link local or multicast address.
Options The current information about the DHCPv6 relay options for the interface
Interface-Id The interface ID option indicating if the option is used or not.
DHCPv6 Relay Agent Prex Delegation Notication
DHCPv6 Relay Agent Prex Delegation Notication feature allows a DHCPv6 server to dynamically delegate IPv6 prexes to a
DHCPv6 client using the DHCPv6 Prex Delegation (PD) option. DHCPv6 prex delegation enables an Internet service provider (ISP) to
automate the process of assigning prexes to a customer premises equipment (CPE) network. The CPE then assigns IPv6 subnets from
the delegated IPv6 prex to its downstream customer interfaces.
This feature description is shown in Figure 17.
