Use this command to enable the addition of sub-option 5 (link selection) and sub-option 11 (server ID override) in option 82 of the DHCP packet received from the DHCP Client. The command can be used in both Global Config mode and Interface Config mode.
The bootpdhcprelay server-override command, when issued in Global Config mode, enables the server-override globally. All routing interfaces then have the feature enabled. Any DHCP packet received from a DHCP client will have sub-option 5 and sub-option 11 for option 82 added to the packet.
When this command is issued in Interface Config mode, server-override is enabled for that interface only.
| Default | server-override is disabled globally and on all interfaces |
| Format | bootpdhcprelay server-override |
| Mode |

Example: The following example enables server-override globally.
(Routing)#configure (Routing)(Config)#bootpdhcprelay server-override (Routing)(Config)#
Example: The following example enables server-override on interface 0/26.
(Routing)#configure (Routing)(Config)#interface 0/26 (Routing)(Interface 0/26)#bootpdhcprelay server-override (Routing)(Interface 0/26)#
