Network Feature | Korenix
dynamic failover of the forwarding responsibility to a Backup (secondary) router if the Master
(primary) router becomes unavailable. VRRP provides the advantage of a single default path
that has higher availability without requiring network devices to be reconfigured if a failure
occurs.
The VRRP protocol provides rapid
transition from Master to Backup to
minimize service interruption.
One of the JetBox becomes the Master
and the other becomes a Backup when
the VRRP protocol starts up. Election
of the Master is based on the
configuration file. Both Master and
Backup have identical Virtual IP
Addresses.
When Master becomes unavailable,
traffic between JetBox 9500 #1 and
JetBox 9500 #2 is interrupted. Then
JetBox 9500#2 will take the place as
Master.
