Virtual wire is forwarding traffic on standby resulting in traffic loops and potential network outage.
Standby device is passing traffic, which may create traffic loops and bring down the network.
-- High availability (HA) configured. -- Virtual wire configured.
Do not configure virtual wire on standby devices.
Although you can create this configuration, the standby no longer forwards any traffic, which prevents the traffic loop and potential network outage.
