Host Tracking
Prisma SD-WAN now supports Intelligent Traffic Rerouting (host tracking), use the
reachability tracker to monitor LAN connections consistently and effectively.

Prisma SD-WAN traffic exclusively uses active paths when multiple paths are
established from the Branch to the Data Center (DC). Backup paths are on standby and
ready to activate in case of link or BGP peer failures at the DC ION device,
ensuring uninterrupted service. By enabling Host Reachability
Tracking, you can effectively monitor LAN connections with a tracker
that provides consistent connectivity. As long as the DC ION device can reach the
designated IP address, traffic will remain on the active links. However, if the
tracker fails—indicating a loss of IP reachability—the system will promptly switch
between active and backup paths as necessary, demonstrating its proactive response
to potential issues.
Prisma SD-WAN traffic rerouting is seamless, ensuring uninterrupted service despite
core network connectivity failures. When such issues arise, the system seamlessly
redirects traffic to alternative overlay paths within the same data center,
maintaining service continuity and enhancing network resilience.
As a result, the branches proactively reroute their traffic to the core network
through alternative routes. This approach effectively prevents potential traffic
black holes, ensuring continuous and reliable network operation.
- Select , and select a site from the list of Data Center sites.
- Click Configure Host Tracking to see the tracked IP address entries and add the new entries.
- The VRF will be enabled only when the associated device supports it. Currently, we support Global VRF, which is Global by default.
- Enter the IP address Tracker IP to enable reachability tracking, and you can effectively monitor LAN connections with a tracker that ensures consistent connectivity.
- Select the Data Center ION Devices from the available devices to reach the designated IP address. Click Save.
