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.

Options

none	Display information about HRFF profiles.
