Examples
Section titled “Examples”Example-1: This data model creates an L3-type Redirect Backup Policy named L4L7_PBR_BKP, which enhances high availability and resilience for Redirect Policies within the same Redirect Health Group, L4L7RedirectHealthGroup.
The Redirect Backup Policy is usually implemented when Resilient Hashing option (resilient_hashing) is enabled in a Redirect Policy. In this case, if a PBR destination specified under apic.tenants.policies.redirect_policy.l3_destinations fails, the traffic is rerouted to a PBR destination (l3_destinations) defined in the Redirect Backup Policy (FW_bkp_Virtual_Interface in this example).
Note that Redirect Backup Policies are not eligible to IP SLA Policies monitoring.
