7.5.3 Checking the Configuration

Prerequisite
The configurations of VRRP fast switchover are complete.
Procedure
Step 1 Run the display vrrp [ interface interface-type interface-number [ virtual-router-id ] ]
command to view information about a specified VRRP group.
----End
Example
Run the display vrrp command, and you can find that the tracked BFD session is in Up state.
For example:
<Quidway> display vrrp
Vlanif211 | Virtual Router 10
Issue 01 (2011-10-26)
The view of the interface that the VRRP backup group belongs to is displayed.
3. Run:
vrrp6 vrid virtual-router-id track bfd-session { session-id | session-
name bfd-configure-name } [ increased value-increased | reduced value-
reduced ]
The normal BFD session is tracked.
increased value-increased: specifies the value by which the priority increases when
the tracked BFD session goes Down. It is an integer ranging from 1 to 255. The
maximum value of the priority is 254 because 255 is reserved for only the IP address
owner.
reduced value-reduced: specifies the value by which the priority decreases when the
tracked BFD session goes Down. The value is an integer ranging from 1 to 254. The
minimum value of the priority is 0. The priority 0 is reserved in the system for special
use. When the backup device receives a VRRP Advertisement packet with the priority
0, it immediately switches to be the master device. By default, the value of the priority
decreases by 10.
NOTE
When configuring the value by which the priority increases or decreases, note that if the priority
of the Backup switch in a backup group is higher than that of the Master switch whose priority
is changed, the fast switchover is performed.
When configuring a VRRP6 backup group to track the status of a BFD session, note the
following points:
l If the parameter session-name bfd-configure-name is specified, the VRRP backup group
can track the status of only dynamic BFD sessions.
l If the parameter session-id is specified, the VRRP backup group can track the status of only
static BFD sessions.
