Configuring EIGRP
Step 5 Click the Networks tab.
Step 6 To add a new network entry, click Add.
The Add EIGRP Network dialog box appears. To remove a network entry, choose an entry in the table
and click Delete.
Step 7 Choose the AS number of the EIGRP routing process from the drop-down list.
Step 8 Enter the IP address of the networks to participate in the EIGRP routing process in the IP Address field.
Note To change a network entry, you must first remove the entry and then add a new one. You cannot edit
existing entries.
Step 9 Enter a network mask to apply to the IP address in the Network Mask field.
Step 10 Click OK.
Enabling EIGRP Stub Routing
You can enable, and configure the adaptive security appliance as an EIGRP stub router. Stub routing
decreases memory and processing requirements on the adaptive security appliance. As a stub router, the
adaptive security appliance does not need to maintain a complete EIGRP routing table because it
forwards all nonlocal traffic to a distribution router. Generally, the distribution router need not send
anything more than a default route to the stub router.
Only specified routes are propagated from the stub router to the distribution router. As a stub router, the
adaptive security appliance responds to all queries for summaries, connected routes, redistributed static
routes, external routes, and internal routes with the message “inaccessible.” When the adaptive security
appliance is configured as a stub, it sends a special peer information packet to all neighboring routers to
report its status as a stub router. Any neighbor that receives a packet informing it of the stub status will
not query the stub router for any routes, and a router that has a stub peer will not query that peer. The
stub router depends on the distribution router to send the correct updates to all peers.
To enable the adaptive security appliance as an EIGRP stub routing process, perform the following steps:
Step 1 On the main ASDM window, choose Configuration > Device Setup > Routing > EIGRP > Setup.
The EIGRP Setup pane appears.
Step 2 Check the Enable EIGRP routing check box.
Step 3 In the EIGRP Process field, enter the autonomous system (AS) number for the EIGRP process. The AS
number can be from 1 to 65535.
Step 4 Click Advanced to configure the EIGRP stub routing process.
The Edit EIGRP Advance Properties dialog box appears.
Step 5 In the Stub area on the Edit EIGRP Process Advanced Properties dialog box, choose one or more of the
EIGRP stub routing processes. Processes include:
• Stub Receive only—Configures the EIGRP stub routing process to receive route information from
the neighbor routers but does not send route information to the neighbors. If this option is selected,
you cannot select any of the other stub routing options.
• Stub Connected—Advertises connected routes.
