Step Command Remarks
35. Enter interface view.
interface interface-type
interface-number
N/A
36. Create a VRRP group and
configure its virtual IP
address.
vrrp vrid virtual-router-id virtual-ip
virtual-address No VRRP group is created by
default.
37. Associate a track entry with a
VRRP group.
vrrp [ ipv6 ] vrid virtual-router-id
track track-entry-number [ reduced
priority-reduced | switchover ]
No track entry is specified for a
VRRP group by default.
This command is supported when
VRRP is operating in both standard
protocol mode and load balancing
mode.
To associate Track with VRRP VF:
Step Command Remarks
38. Enter system view. system-view N/A
39. Enter interface view.
interface interface-type
interface-number
N/A
40. Create a VRRP group and
configure its virtual IP
address.
vrrp vrid virtual-router-id virtual-ip
virtual-address No VRRP group is created by
default.
41. Associate Track with VRRP VF.
• Associate a track entry with the
VRRP VF:
vrrp [ ipv6 ] vrid virtual-router-id
weight track track-entry-number
[ reduced weight-reduced ]
• Configure the LVF to monitor the
AVF status through the track
entry:
vrrp [ ipv6 ] vrid virtual-router-id
track track-entry-number
forwarder-switchover
member-ip ip-address
Use at least one command.
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 function takes
effect only when VRRP is operating
in load balancing mode.
Associating Track with static routing
A static route is a manually configured route. With a static route configured, packets to the specified
destination are forwarded through the path specified by the administrator.
The disadvantage of using static routes is that they cannot adapt to network topology changes. Faults or
topological changes in the network can make the routes unreachable, causing network breaks.
To prevent 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, avoiding network breaks and enhancing network reliability.
To check the accessibility of a static route in real time, establish association between Track and the static
route.
