The remote identification is configured globally. By default, the DHCPv6 relay agent type 3 DUID (system mac) is used as the
remote-ID value. You can optionally configure a customized string. In VLT cases, VLT MAC address is used to generate the
DUID.
The prefix is an optional parameter to be configured globally. You can configure hostname, VRF Name, hostname, and VRF name
or customized string as prefix. Optionally, you can configure DHCPv6 hostname.
The prefix and the remote identification are separated by the colon ( : ). For example, prefix : Remote Identification.
Following are the different formats of the remote-ID value with different configuration of the prefix.
Host name as prefix :
<Host name> : <Remote identification>
e.g.: DELL OS10:90b11cf4a65d
VRF Name as prefix :
<VRF Name of the interface> : <Remote identification>
e.g.: RED:90b11cf4a65d
Both Host name and VRF Name as prefix :
<Host name>-<VRF Name of the interface> : <Remote identification>
e.g.: DELL OS10-RED:90b11cf4a65d
