ipv6 dhcp relay
Enterasys C3 Configuration Guide 30-11
Example
This example configures routing interface VLAN 7 to be a DHCPv6 server, using the address pool
named PoolA.
C3(su)->router(Config)# interface vlan 7
C3(su)->router(Config-if(Vlan 7))# ipv6 dhcp server PoolA
ipv6 dhcp relay
This command configures an interface for DHCPv6 relay agent functionality.
Syntax
ipv6 dhcp relay {destination dest-addr [interface intf] | interface vlan vlan-id}
[remote-id {duid-ifid | user-defined-string}]
no ipv6 dhcp relay {destination dest-addr [interface intf] | interface intf}
Parameters
Defaults
If remote-id is not specified, the Relay Agent Information Option Remote-ID sub-option is not
added to relayed messages.
Mode
Router interface configuration: C3(su)->router(Config-if(Vlan 1))#
Usage
Use this command to configure a routing interface as a DHCPv6 relay agent.
An interface can be configured as either a DHCPv6 server or a DHCPv6 relay agent, but not both.
Use the no form of this command to remove DHCPv6 relay agent functionality from an interface.
destination dest-addr Specifies the IPv6 address of a DHCPv6 relay server. This IPv6 address
can be a global address, a multicast address, or a link-local address.
If the address is a multicast or link-local address, then you must specify
the interface to be used to contact the relay server with the interface
parameter.
interface intf (Optional) Specifies the interface to be used to contact the relay server if
the destination address is a multicast or link-local address. The interface
is identified by port type.unit number.port number. For example,
ge.3.1.
interface vlan vlan-id If destination dest-addr is not specified, then an interface must be
specified and the DHCPV6-ALL-AGENTS multicast address (FF02::1:2)
is used to relay DHCPv6 messages to the relay server.
remote-id {duid-ifid |
user-defined-string}
(Optional) Specifies that the Relay Agent Information Option
Remote-ID sub-option is to be added to relayed messages.
Specifying duid-ifid causes the remote ID to be derived from the relay
agent’s DUID and the relay interface number. Alternatively, you can
specify the remote ID as a user-defined-string of alpha-numeric
characters. Refer to RFC 3046 and RFC 4649 for more information about
the Remote-ID option.
