Chapter 30 Configuring EIGRP
Monitoring EIGRP
To disable EIGRP split horizon, perform the following steps:
Step 1 In the main ASDM window, choose Configuration > Device Setup > Routing > EIGRP > Interfaces.
The Interface pane appears and displays the EIGRP interface configurations.
Step 2 Double-click an interface entry or choose the entry and click Edit.
The Edit EIGRP Interface Entry dialog box appears.
Step 3 Choose the EIGRP Autonomous system (AS) number from the drop-down list, which is populated from
system numbers that were set up when you enabled the EIGRP routing process.
Step 4 Uncheck the Split Horizon check box.
Step 5 Click OK.
Restarting the EIGRP Process
To restart an EIGRP process or clear redistribution or counters, perform the following steps:
Step 1 In the main ASDM window, choose Configuration > Device Setup > Routing > EIGRP > Setup.
The EIGRP Setup pane appears.
Step 2 Click Reset.
Monitoring EIGRP
You can use the following commands to monitor the EIGRP routing process. For examples and
descriptions of the command output, see the command reference. Additionally, you can disable the
logging of neighbor change messages and neighbor warning messages.
To monitor or disable various EIGRP routing statistics, perform the following steps:
Step 1 In the main ASDM window, choose Monitoring > Routing > EIGRP Neighbor.
Each row represents one EIGRP neighbor. For each neighbor, the list includes its IP address, the
interface to which the neighbor is connected, the holdtime, the uptime, the queue length, the sequence
number, the smoothed round trip time, and the retransmission timeout. The list of possible state changes
are the following:
• NEW ADJACENCY—A new neighbor has been established.
• PEER RESTARTED—The other neighbor initiates the reset of the neighbor relationship. The router
getting the message is not the one resetting the neighbor.
• HOLD TIME EXPIRED—The router has not heard any EIGRP packets from the neighbor within
the hold-time limit.
• RETRY LIMIT EXCEEDED—EIGRP did not receive the acknowledgement from the neighbor for
EIGRP reliable packets, and EIGRP has already tried to retransmit the reliable packet 16 times
without any success.
