Figure 23: Switching Device Acting as an Extended Relay Server
DHCPv6 Options
NOTE: MX Series routers do not support DHCPv6.
DHCPv6 provides several options that can be used to insert information into the DHCPv6
request packets that are relayed to a server from a client. These options are equivalent
to the sub-options of DHCP option 82.
•
Option 37—Identifies the remote host. Option 37 is equivalent to the remote-id
sub-option of DHCP option 82.
•
Option 18—Identifies the interface on which the DHCP request packet was received
from the client. Option 18 is equivalent to the circuit-id sub-option of DHCP option 82.
•
Option 16—Identifies the vendor of the hardware on which the client is hosted. Option
16 is equivalent to the vendor-id sub-option of DHCP option 82.
DHCPv6 options are not enabled automatically when DHCPv6 snooping is enabled on
a VLAN. They must be configured using the dhcpv6-options statement.
