FAILOVER
circuit-failover
Overview
Use this command to enable the VRRP circuit failover feature.
Circuit failover enables the device to take action if the uplink interface goes down,
so that the VRRP backup, whose uplink interface is still active, takes over as VRRP
master. See the Usage section below and the
for more information.
Use the
no
variant of this command to disable this feature.

Mode
Router Configuration
Usage
You can use Circuit Failover to monitor up to 32 interfaces per VRRP instance. If a
VRRP instance is configured to monitor multiple interfaces, the VRRP priority will
be cumulatively decremented by the configured delta for each interface as it goes
down.
For example, if VRRP is configured to monitor VLAN2 and VLAN3 with the
commands:
awplus#
configure terminal
awplus(config)#
interface vlan1
awplus(config-if)#
ip address 192.168.1.1/24
awplus(config-if)#
exit
awplus(config)#
router vrrp 1 vlan1
awplus(config-router)#
virtual-ip 192.168.1.10 backup
awplus(config-router)#
priority 100
awplus(config-router)#
circuit-failover vlan2 10
awplus(config-router)#
circuit-failover vlan3 20
Parameter
Description
<interface>
The interface of the router that is monitored. The interface must
exist on the router, and is usually an upstream interface. Should the
interface go down, then another router that is configured as a
backup router in the group takes over as the master. You should
configure the circuit failover on an interface other than the active
VRRP interface - generally the uplink interface.
<
1-253
>
Delta value. The value by which virtual routers decrement their
priority value during a circuit failover event. Configure this value to
be greater than the difference of priorities on the master and
backup routers. In the case of failover, this priority delta value is
subtracted from the current VR Master Router priority value.
