Step Command Remarks
4. Associate Track with IPv6 PBR.
• Set the output interface, and associate it
with a track entry:
apply output-interface { interface-type
interface-number [ track
track-entry-number ] }&<1-n>
• Set the next hop, and associate it with a
track entry:
apply next-hop [ vpn-instance
vpn-instance-name | inbound-vpn ]
{ ipv6-address [ direct ] [ track
track-entry-number ] }&<1-n>
• Set the default output interface, and
associate it with a track entry:
apply default-output-interface
{ interface-type interface-number [ track
track-entry-number ] }&<1-n>
• Set the default next hop, and associate it
with a track entry:
apply default-next-hop [ vpn-instance
vpn-instance-name | inbound-vpn ]
{ ipv6-address [ direct ] [ track
track-entry-number ] }&<1-n>
Use at least one of the
commands.
Associating Track with interface backup
Interface backup allows interfaces on a device to back up each other, with the active interface
transmitting data and the standby interfaces staying in backup state. When the active interface or the link
where the active interface resides fails and data cannot be transmitted, a standby interface is brought up
to transmit data. This enhances the reliability of the network. For more information, see "Configuring
interface backup."
Associate a standby interface with a track entry so that the standby interface can detect the status of the
active interface by checking the status of the track entry, and change its status.
• The Positive state of the track entry shows that the link where the active interface resides works
correctly, and the standby interfaces stay in backup state.
• The Negative state of the track entry shows that the link where the active interface resides has failed,
and a standby interface changes to the active interface for data transmission.
• The always NotReady state of the track entry shows that the association does not take effect and
each interface keeps its original forwarding state. When the track entry turns to NotReady from
other state, a standby interface becomes the active interface.
You can associate a nonexistent track entry with an interface. The association takes effect only after you
use the track command to create the track entry.
