When adding a device in high availability (HA) to SD-WAN Devices, you now have the
option to add its HA peer simultaneously. This feature streamlines configuration by
enabling you to
configure both devices from a single
configuration page, ensuring configuration consistency between the active
and passive devices. When selected, the system identifies the HA peer and displays
the device name, prompting you to specify a site name for the peer. Both devices are
then created with matching configurations, which is critical since SD-WAN
configurations between HA pairs should be identical except for site names.
Prior to this enhancement, you needed to add each device in an HA pair separately to
SD-WAN Devices, which could lead to configuration mismatches. The system would
display warnings when such mismatches were detected, but the manual correction
process was error-prone.
With this feature, any configuration changes made to one device
automatically propagate to its peer, maintaining synchronization between the
devices. This feature is useful when adding devices to VPN clusters, as SD-WAN
requires both HA peers to have matching configurations for proper functioning during
failover events.
If you attempt to configure HA devices separately, the SD-WAN plugin will prevent
this operation and guide you to add HA pairs instead. This safeguard, along with
visual indicators that alert you to any configuration mismatches between HA pairs,
helps maintain the integrity of your SD-WAN deployment and ensures proper failover
functionality in your high availability environment.
