Web Agent Procedure

To create and modify IPX RIP filters using the Web Agent:

  1. In the navigation pane, expand the Routing > IPX > RIP folders, and then click Filters.

    2. The IPX RIP Filters Web page is displayed in the content pane. See Figure�178. Only the CREATE button is displayed when no filters are configured.

  1. Select CREATE to create a new filter. The Add IPX RIP Filter Web page is displayed. See Figure�179.

Figure�179:�Add IPX RIP Filter Web Page


  1. See Table�128 to modify the Add IPX RIP Filter parameters.
  2. Click APPLY to save your changes, or CANCEL to restore previous settings.

Table�128:�Add IPX RIP Filter Parameters �
Parameter
Description
Select
The Select check box selects the IPX Interface. This box only appears with the IPX RIP Filters Web page.
Interface
Select the interface to which this filter will be applied to RIP packets sent and/or received on the interface.
Precedence
Specify the filter precedence (in order of importance) where 0 is most important.

Note: All filters on the same interface, must be assigned a unique filter precedence.

Start Network
Specify the first IPX network number in the range.The default is 0
End Network
Specify the last IPX network number in the range.The default is 0
Direction
Select the direction of the filter. Options are:
  • Inbound - Apply the filter only to RIP packets received on the interface.
  • Outbound - Apply the filter only to RIP packets sent on the interface.
  • Both - Apply the filter to RIP packets both sent and received on the interface.
  • The default is Outbound
Filter/Suppress
Disable the IPX networks (within the specified range in the filter) to be filtered (inbound) or suppressed (outbound).
  • Filtered - Apply the filter only to RIP packets received (inbound direction) on the interface.
  • Suppressed - Apply the filter only to RIP packets sent (outbound direction) on the interface.
Enable allows you to filter and suppress traffic and is the default. Select Disable to disable the filtering and suppression of traffic.The default is Enable.
Ticks
Specify the time (in ticks) that the packet takes to reach the network number you specified. A tick is approximately 1/18th of a second. This entry is used to override the value in the RIP packet.
If you enter 0, there will be no override in the transmission of data on the network.The default is 0
Hops
Specify the number of routers (hops) that the packet must pass through before reaching the network number associated with the IPX interface. This entry is used to override the value in the RIP packet.
If you enter 0, there will be no override in the transmission of data on the network. The default is 0

Example 1: Configuring your switch to suppress advertising of network 10

To configure your switch to suppress the advertising of network 10 on the IPX interface named Backbone, complete the following steps:

  1. In the navigation pane, expand the Routing > IPX > RIP folders, and then click Filters.

    2. The IPX RIP Filters Web page is displayed in the content pane. See Figure�178.

  2. Select CREATE to create a new filter. The Add IPX RIP Filter Web page is displayed. See Figure�179.
  3. Configure the following parameters on the Add IPX RIP Filter Web page:
    1. Select Backbone in the Interface field.
    2. Enter 0 in the Precedence field.
    3. Enter 10 in the Start Network field.
    4. Enter 10 in the End Network field.
    5. In the Direction field, select Outbound.
    6. In the Filter/Suppress field, select Enable.
    7. Enter 0 in the Ticks and Hops fields.
  4. Click Apply to save your changes, or CANCEL to restore previous settings.

The filter created in this example ensures that all advertising of network 10 from the interface labeled Backbone is suppressed.

Example 2: Suppress Advertising of all Networks Except 10

To configure your switch to suppress the advertising of all networks except network 10 on the IPX interface named Backbone, you must first create two filters.

To create filter 1 from the Web Agent:

  1. In the navigation pane, expand the Routing > IPX > RIP folders, and then click Filters.

    2. The IPX RIP Filter Web page is displayed in the content pane. See Figure�178.

  2. Select Create to create a new filter. The Add IPX RIP Filter Web page is displayed.
  3. Configure the following parameters:
    1. Select Backbone in the Interface field.
    2. Enter 0 in the Precedence field.
    3. Enter 10 in the Start Network field.
    4. Enter 10 in the End Network field.
    5. Select Outbound in the Direction field.
    6. Select Disable in the Filter/Suppress field.
    7. Enter 0 in the Ticks and Hops fields.

Filter 1 ensures that the advertising of network 10 on the interface Backbone will not be suppressed. To suppress all other networks, proceed with the creation of Filter 2.

To create Filter 2 from the Web Agent:

  1. Repeat steps 1- 2 in the creating Filter #1 procedure.
  2. Configure the following parameters:
    1. Select Backbone in the Interface field.
    2. Enter 1 in the Precedence field.
    3. Enter 0 in the Start Network field.
    4. Enter ffffffff in the End Network field.
    5. Select Outbound in the Direction field.
    6. Select Enable in the Filter/Suppress field.
    7. Enter 0 in the Ticks and Hops fields.
  3. Click APPLY to save your changes, or CANCEL to restore previous settings.

Filter 2 ensures that the advertising of all networks on the interface Backbone will be suppressed.

Together, Filter 1 and Filter 2 will act to suppress all network advertising with the exception of network 10. It is important to note that Filter 2 had the Precedence field set to 1 and Filter 1 had the Precedence field set to 0. Any filter with a Precedence of 0 will always override a filter with a precedence of 1 or higher.
