III. Configuration procedure
Configure Router A:
# Enter system view.
<3Com A> system-view
# Create a detect group numbered 8 and enter its view.
[3Com A] detect-group 8
# Add an IP address of 10.1.1.4 with sequence number 1 to the detect group, taking
192.168.1.2 as the next hop IP address.
[3Com A-detect-group-8] detect-list 1 ip address 10.1.1.4 nexthop 192.168.1.2
# Reference the detect group in a static route, having the route validated when the
detect group is reachable.
[3Com A] ip route-static 10.1.1.4 24 192.168.1.2 detect-group 8

3.4 Application of Auto Detect in VRRP

You may reference a detect group in a VRRP standby group to control the preference
levels of the standby interface in the standby group, implementing automatic switching
between the master and backup routers as follows:
When the detect group is unreachable, decrease the preference value of the
standby interface in the standby group.
When the detect group is reachable, restore the preference value of the standby
interface in the standby group.

3.4.1 Configuring Auto Detect for VRRP

Note:
Before proceeding with the following configurations, you must define a detect group
and complete necessary VRRP configuration tasks.
