Description
Use the vrrp vrid command to implement VRRP using the auto detect function.
Use the undo vrrp vrid command to remove the auto detect function from VRRP.
When a detect group is referenced for implementing VRRP, the router does one of the
following:
z When the detect group is unreachable, decrease the preference value of the
standby group.
z When the detect group is reachable, restore the preference value of the standby
group.
Example
# Create a detect group numbered 10 and add IP address 202.13.1.55 to the group.
<3com> system-view
System View: return to User View with Ctrl+Z.
[3com] detect-group 10
[3com-detect-group-10] detect-list 1 ip 202.13.1.55
# Decrease the preference value of standby group 1 by 20 when detect group 10 is
unreachable.
