bfd check-ctrl-plane-failure
To enable Bidirectional Forwarding Detection (BFD) control plane failure checking for the Intermediate
System-to-Intermediate System (IS-IS) routing protocol, use the bfd check-control-plane-failure command
in router configuration mode. To disable control plane failure detection, use the no form of this command
bfd check-ctrl-plane-failure
no bfd check-ctrl-plane-failure
Syntax Description
This command has no arguments or keywords.
Command Default
BFD control plane failure checking is disabled.
Command Modes
Router configuration (config-router)
Command History
ModificationRelease
This command was introduced.Cisco IOS XE Denali 16.3.1
Usage Guidelines
The bfd check-ctrl-plane-failure command can be configured for an IS-IS routing process only. The command
is not supported on other protocols.
When a switch restarts, a false BFD session failure can occur, where neighboring routers behave as if a true
forwarding failure has occurred. However, if the bfd check-ctrl-plane-failure command is enabled on a switch,
the router can ignore control plane related BFD session failures. We recommend that you add this command
to the configuration of all neighboring routers just prior to a planned router restart, and that you remove the
command from all neighboring routers when the restart is complete.
Examples
The following example enables BFD control plane failure checking for the IS-IS routing protocol:
Device> enable
Device# configuration terminal
Device(config)# router isis
Device(config-router)# bfd check-ctrl-plane-failure
Device(config-router)# end
