show hfrr profiles
Syntax
show hfrr profiles <brief |extensive>
Description
Display host fast reroute (HFRR) profile information.
HFRR adds a precomputed protection path into the Packet Forwarding Engine, such that if a link between a provider edge device and a server farm becomes unusable for forwarding, the Packet Forwarding Engine can use another path without having to wait for the router or the protocols to provide updated forwarding information.
