Chapter 8 Configuring EIGRP
Configuring Advanced EIGRP
The following example shows how to configure equal cost load balancing for EIGRP over IPv4 with a
maximum of six equal cost paths:
switch# config t
switch(config)# router eigrp Test1
switch(config-router)# maximum-paths 6
switch(config-router)# copy running-config startup-config
Configuring Graceful Restart for EIGRP
You can configure graceful restart or nonstop forwarding for EIGRP. See the “Graceful Restart and High
Availability” section on page 8-7.
Note Graceful restart is enabled by default.
BEFORE YOU BEGIN
Ensure that you have enabled the EIGRP feature (see the “Enabling the EIGRP Feature” section on
page 8-9).
An NSF-aware router must be up and completely converged with the network before it can assist an
NSF-capable router in a graceful restart operation.
Neighboring devices participating in the graceful restart must be NSF-aware or NSF-capable.
Ensure that you are in the correct VDC (or use the switchto vdc command).
SUMMARY STEPS
1. config t
2. router eigrp instance-tag
3. address-family {ipv4 | ipv6} unicast
4. graceful-restart
5. timers nsf converge seconds
6. timers nsf route-hold seconds
7. timers nsf signal seconds
8. copy running-config startup-config
Step 4
maximum-paths num-paths
Example:
switch(config-router-af)# maximum-paths 5
Sets the number of equal cost paths that
EIGRP will accept in the route table. The
range is from 1 to 16. The default is 8.
Step 5
copy running-config startup-config
Example:
switch(config-router-af)# copy running-config
startup-config
(Optional) Saves this configuration change.
