Filter Rules
The Filter Rules pane displays the route filtering rules configured for the EIGRP routing process. Filter
rules let you control which routes are accepted or advertised by the EIGRP routing process.
Each row of the Filter Rule table describes a filter rule for a specific interface or routing protocol. For
example, a filter rule with a direction of “in” on the outside interface would apply filtering to any EIGRP
updates received on the outside interface. A filter rule with a direction of “out” with OSPF 10 specified
as the routing protocol would apply the filter rules to routes redistributed into the EIGRP routing process
in outbound EIGRP updates.
To configure filter rules, do one of the following:
• To add a filter rule, click Add. The Add Filter Rules dialog box appears.
• To edit a filter rule, select the filter rule in the table and click Edit. You can also double-click a filter
rule to edit the rule. The Edit Filter Rules dialog box appears.
• To remove a filter rule, select the filter rule in the table and click Delete.
Fields
The Add/Edit EIGRP Filter Rule Dialog box fields:
• EIGRP—The autonomous system number of the EIGRP routing process.
• Direction—Select “in” for rules that filter routes from incoming EIGRP routing updates. Select
“out” to filter routes from EIGRP routing updates sent by the security appliance.
• Routing process—(For outgoing filters only) Specifies the type of route being filtered. You can filter
routes redistributed from static, connected, RIP, and OSPF routing processes. Filters that specify a
routing process filter those routes from updates sent on all interfaces.
• Id—The OSPF process ID.
• Interface—The interface the filter applies to.
• Add—Opens the Network Rule dialog box.
• Edit—Opens the Network Rule dialog box for the selected network rule.
Add/Edit Network Rule dialog box lets you define an access list for the filter rule. The dialog box
contains the following fields:
• Action—Select Permit to allow the specified network to be advertised. Select Deny to prevent the
specified network from being advertised.
• IP Address—Type IP address of the network being permitted or denied. To permit or deny all
addresses, use the IP address 0.0.0.0 with a network mask of 0.0.0.0.
• Netmask—Specify the network mask applied to the network IP address. You can type a network
mask into this field or select one of the common masks from the list.
