Associating Track with static routing

A static route is a manually configured route to route packets. For more information about static route
configuration, see Layer 3—IP Routing Configuration Guide.
Static routes cannot adapt to network topology changes. Link failures or network topological changes
can make the routes unreachable and cause communication interruption.
To resolve this problem, configure another route to back up the static route. When the static route is
reachable, packets are forwarded through the static route. When the static route is unreachable, packets
are forwarded through the backup route.
To check the accessibility of a static route in real time, associate the Track module with the static route.
If you specify the next hop but not the output interface when configuring a static route, you can configure
the static routing-Track-detection module collaboration. This collaboration enables you to verify the
accessibility of the static route based on the track entry state.
If the track entry is in Positive state, the following conditions exist:
•
The next hop of the static route is reachable.
The configured static route is valid.
• If the track entry is in Negative state, the following conditions exist:
The next hop of the static route is not reachable.
The configured static route is invalid.
If the track entry is in NotReady state, the following conditions exist:
•
The accessibility of the next hop of the static route is unknown.

Remarks
By default, no track entry is
specified for a VRRP group.
This command is supported when
VRRP is operating in both standard
mode and load balancing mode.
Remarks
N/A
N/A
By default, no track entry is
specified for a VF.
This command is configurable when
VRRP is operating in standard mode
or load balancing mode. However,
this command takes effect only
when VRRP is operating in load
balancing mode.
