Syntax
Release Information
Command introduced in Junos OS Release 12.2.
Description
Display Host fast reroute (HFRR) profile information.
HFRR adds a precomputed protection path into the Packet Forwarding Engine (PFE), such that if a link between a provider edge device and a server farm becomes unusable for forwarding, the PFE can use another path without having to wait for the router or the protocols to provide updated forwarding information.
