• If the status of the track entry is Invalid, the operations such as setting the outgoing interface and
next hop, and setting the default outgoing interface and next hop take effect, and can be used to
for packet forwarding.
Configuration prerequisites
Before configuring track-policy routing, create a policy or a policy node and configure the match rules
as well.
Configuration procedure
Follow these steps to configure the track-policy routing collaboration:
To do… Use the command… Remarks
Enter system view system-view —
Create a policy or policy node
and enter the policy view policy-based-route policy-name
{ deny | permit } node node-number
Required
Set the packet length match rule
if-match packet-length min-len
max-len
Match an ACL if-match acl acl-number
Required
Use either command.
Specify the packet outgoing
interface and associate it with a
track entry
apply output-interface interface-type
interface-number [ track
track-entry-number ] [ interface-type
interface-number [ track
track-entry-number ] ]
Specify the next hop of packets
and associate it with a track entry
apply ip-address next-hop
ip-address [ track track-entry-number ]
[ ip-address [ track track-entry-number ] ]
Specify the default outgoing
interface of packets and associate
it with a track entry
apply default output-interface
interface-type interface-number [ track
track-entry-number ] [ interface-type
interface-number [ track
track-entry-number ] ]
Specify the default next hop of
packets and associate it with a
track entry
apply ip-address default next-hop
ip-address [ track track-entry-number]
[ ip-address [ track track-entry-number] ]
Use at least one of the four
commands.
NOTE:
•
The track entry to be associated with the policy routing can be a nonexistent one. After you use the track
command to create the track entry, the association takes effect.
• For more information about policy routing configuration, see IP Unicast Policy Routing Configuration in
the IP Routing Volume.
Configuring Track-Interface Backup Collaboration
Interface backup allows interfaces on a device to back up each other, with the main interface
transmitting data, and the backup interfaces staying in the backup state. When the main interface or the
