Chapter 8 Configuring EIGRP
Configuring Advanced EIGRP
DETAILED STEPS
The following example shows how to configure graceful restart for EIGRP over IPv6 using the default
timer values:
switch# config t
switch(config)# router eigrp Test1
switch(config-router)# address-family ipv6 unicast
switch(config-router-af)# graceful-restart
switch(config-router-af)# copy running-config startup-config
Command Purpose
Step 1
config t
Example:
switch# config t
switch(config)#
Enters configuration mode.
Step 2
router eigrp instance-tag
Example:
switch(config)# router eigrp Test1
switch(config-router)#
Creates a new EIGRP process with the
configured instance tag. The instance tag can
be any case-sensitive alphanumeric string up
to 20 characters.
If you configure an instance-tag that does not
qualify as an AS number, you must use the
autonomous-system command to configure
the AS number explicitly or this EIGRP
instance will remain in the shutdown state.
Step 3
address-family {ipv4 | ipv6} unicast
Example:
switch(config-router)# address-family ipv4
unicast
switch(config-router-af)#
Enters the address-family configuration mode.
This command is optional for IPv4.
Step 4
graceful-restart
Example:
switch(config-router-af)# graceful-restart
Enables graceful restart. This feature is
enabled by default.
Step 5
timers nsf converge seconds
Example:
switch(config-router-af)# timers nsf converge
100
Sets the time limit for the convergence after a
switchover. The range is from 60 to 180
seconds. The default is 120.
Step 6
timers nsf route-hold seconds
Example:
switch(config-router-af)# timers nsf
route-hold 200
Sets the hold time for routes learned from the
graceful restart-aware peer. The range is from
20 to 300 seconds. The default is 240.
Step 7
timers nsf signal seconds
Example:
switch(config-router-af)# timers nsf signal 15
Sets the time limit for signaling a graceful
restart. The range is from 10 to 30 seconds.
The default is 20.
Step 8
copy running-config startup-config
Example:
switch(config-router-af)# copy running-config
startup-config
(Optional) Saves this configuration change.
