Example:
switch(config-if-glbp)# weighting
110 lower 95 upper 105
Step 7

Example:
switch(config-if-glbp)# weighting
track 2 decrement 20
Step 8

seconds ]
Example:
switch(config-if-glbp)# forwarder
preempt delay minimum 60
Step 9
ip [ ip-address [secondary]]
Example:
switch(config-if-glbp)# ip
192.0.2.10
Step 10
show glbp interface-type number
Example:
switch(config-if-glbp)# show glbp
ethernet 1/2
Step 11
copy running-config startup-config
Example:
switch(config-if-glbp)# copy
running-config startup-config
The following example shows how to configure GLBP weighting and tracking on Ethernet 1/2:
switch# config t
switch(config)# track 2 interface ethernet 2/2 ip routing
switch(config)# interface ethernet 1/2
switch(config-if)# glbp 1
switch(config-if-glbp)# weighting 110 lower 95 upper 105
switch(config-if-glbp)# weighting track 2 decrement 20
switch(config-if-glbp)# copy running-config startup-config

Purpose
Specifies the initial weighting value and the upper and
lower thresholds for a GLBP gateway. The maximum range
is from 1 to 254. The default weighting value is 100. The
lower range is from 1 to 253. The upper range is from 1 to
254.
Specifies an object to be tracked that affects the weighting
of a GLBP gateway. The value argument specifies a
reduction in the weighting of a GLBP gateway when a
tracked object fails. The range is from 1 to 255.
(Optional) Configures the router to take over as AVF for a
GLBP group if the current AVF for a GLBP group falls
below its low weighting threshold. The range is from 0 to
3600 seconds.
This command is enabled by default with a delay of
30 seconds.
Enables GLBP on an interface and identifies the primary IP
address of the virtual gateway.
After you identify a primary IP address, you can use the
glbp group ip command again with the secondary keyword
to indicate additional IP addresses supported by this group.
If you only use the ip keyword, GLBP learns the virtual IP
address from the neighbors.
(Optional) Displays GLBP information for an interface.
(Optional) Saves this configuration change.
