Monitoring Enhanced Object Tracking
Use the privileged EXEC or user EXEC commands in
to display enhanced object tracking
information.
Step 1
configure terminal
Enter global configuration mode.
Step 2
access-list
access-list-number
Define an extended IP access list. Configure any optional
characteristics.
Step 3
route-map
map-tag
[
permit | deny
]
[
sequence-number
]
Enter route-map configuration mode and define conditions for
redistributing routes from one routing protocol to another.
Step 4
match ip address {
access-list number |
access-list name
}
Distribute any routes that have a destination network number address
that is permitted by a standard or extended access list or performs
policy routing on packets. You can enter multiple numbers or names.
Step 5
set ip next-hop dynamic dhcp
For DHCP networks only. Set the next hop to the gateway that was
most recently learned by the DHCP client.
Step 6
set interface
interface-id
For static routing networks only. Indicate where to send output
packets that pass a match clause of a route map for policy routing.
Step 7
exit
Exit route-map configuration mode.
Step 8
ip local policy route-map
map-tag
Identify a route map to use for local policy routing.
Step 9{
ip route
prefix mask
{
ip-address |
interface-id
[
ip-address
]} [
distance
] [
name
]
[
permanent | track
track-number
] [
tag tag
]
For static routing networks only. Establish static routes.
Entering
track
track-number
specifies that the static route is installed
only if the configured track object is up.
Step 10
end
Return to privileged EXEC mode.
Step 11
show ip route track table
Display information about the IP route track table.
Step 12
copy running-config startup-config
(Optional) Save your entries in the configuration file.
