interfaces dataplane <interface-name> vif <vif-id> dhcp-options no-rfc3442

Disables support for the classless static route option for DHCP on a virtual interface.

set interfaces dataplane interface-name vif vif-id dhcp-options no-rfc3442
delete interfaces dataplane interface-name vif vif-id dhcp-options no-rfc3442
show interfaces dataplane interface-name vif vif-id dhcp-options

The classless static route option for DHCP is enabled.

interface-name

The vRouter can only use interfaces that are available to the operating system kernel (that is, interfaces that physically exist on the system) and have been created in the configuration tree and configured with an IP address.

The vRouter automatically creates configuration nodes for all available physical interfaces on startup.

If you want to use an interface with a specific function (say, BGP) the interface must be enabled within the configuration node for that function (for example, within the BGP configuration node).

vif-id
Multinode. The ID of a virtual interface. The ID ranges from 1 through 4094.
no-rfc3442
Removes the classless static route option (121) from the parameter request list that a DHCP client sends to the DHCP server. For further information, refer to RFC 3442 at https://tools/ietf.org/html/refc3442.

Configuration mode


interfaces {    
   dataplane interface-name {
      vif vif-id {
         dhcp-options {
            no-rfc3442
         }
      }
   }
}
Note: This command is relevant only if the dhcp option has been set by using interfaces dataplane <interface-name> vif <vif-id> address.
Note: Normally, this command is not required. It would be used only if the remote DHCP server is configured to provide classless static routes, but these routes are not required on the router that is configured to use the DHCP address.

Use the set form of this command to disable support for the DHCP classless static route option on a virtual interface.

Use the delete form of this command to re-enable support for the DHCP classless static route option on a virtual interface.

Use the show form of this command to display the status of the DHCP classless static route option on a virtual interface.
