Configuring Bfd Support For Hsrp - Cisco Catalyst 9500 series Configuration Manual

Configuring Bidirectional Forwarding Detection

Configuring BFD Support for HSRP

Perform this task to enable BFD support for Hot Standby Router Protocol (HSRP.) Repeat the steps in this
procedure for each interface over which you want to run BFD sessions to HSRP peers.
HSRP supports BFD by default. If HSRP support for BFD has been manually disabled, you can reenable it
at the router level to enable BFD support globally for all interfaces or on a per-interface basis at the interface
level.
Before You Begin
• HSRP must be running on all participating routers.
• Cisco Express Forwarding must be enabled.
