Enabling/Disabling RDP

Configuring RDP

page 29-8

OmniSwitch AOS Release 6 Network Configuration Guide

RDP is included in the base software and is available when the switch starts up. However, by default this 
feature is not operational until it is enabled on the switch.

To enable RDP operation on the switch, use the following command:

-> ip router-discovery enable

Once enabled, any existing RDP interfaces on the switch that are also enabled will activate and start to 
send initial advertisements. See 

 for more information.

To disable RDP operation on the switch, use the following command:

-> ip router-discovery disable

Use the 

 command to determine the current operational status of RDP on the 

switch.

An RDP interface is created by enabling RDP for an existing IP router interface, which is then advertised 
by RDP as an active router on the local network. Note that an RDP interface is not active unless RDP is 
also enabled for the switch.

To create an RDP interface, enter ip router-discovery interface followed by the name of the IP router 
interface, and then enable. For example, the following command creates an RDP interface for the IP router 
interface named Marketing:

-> ip router-discovery interface Marketing enable

The IP router interface name is the name assigned to the interface when it was first created. For more 
information about creating IP router interfaces, see 

The first time an RDP interface is enabled, it is not necessary to enter enable as part of the command. 
However, if the interface is subsequently disabled, then entering enable is required the next time this 
command is used. For example, the following sequence of commands initially enables an RDP interface 
for the Marketing IP router interface, then disables and again enables the same interface:

-> ip router-discovery interface Marketing

-> ip router-discovery interface Marketing disable

-> ip router-discovery interface Marketing enable

When the above RDP interface becomes active, advertisement packets are transmitted on all active ports 
that belong to the VLAN associated with the Marketing interface. These packets contain the IP address 
associated with the Marketing interface for the purposes of advertising this interface on the network.

When an RDP interface is created, it is automatically configured with the following default parameter 
values:

Advertisement destination address.

All systems multicast (224.0.0.1)

Advertisement time interval defined by 
maximum and minimum values.

Maximum = 600 seconds
Minimum = 450 seconds (0.75 * maximum value)
