Configuring Bfd For Is-Is - Cisco ME 3400 Software Configuration Manual

Chapter 35 Configuring IP Unicast Routing
If you try to configure OSPF BFD on a Layer 2 interface, the configuration is not recognized.
Note
This is an example of configuring BFD for OSPF on all OSPF interfaces:
Switch(config)# router ospf 109
Switch(config-router)# bfd all-interfaces
Switch(config-router)# exit
Configuring BFD for OSPF on an Interface
Beginning in privileged EXEC mode, follow these steps to configure OSFP BFD on an individual
interface:
Command
Step 1
configure terminal
Step 2 router ospf process- id
Step 3 exit
Step 4 interface interface-id
Step 5
ip ospf bfd
Step 6
end
Step 7 show bfd neighbors [detail]
Step 8 copy running-config startup-config
To disable OSPF BFD on an interface, enter the no ip osfp bfd or the ip ospf bfd disable interface
configuration command on the interface.
This is an example of configuring BFD for OSPF on a single interface:
Switch(config)# router ospf 109
Switch(config-router)# exit
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# ip ospf bfd

Configuring BFD for IS-IS

When you start BFD sessions for IS-IS, IS-IS must be running on all devices participating in BFD. You
can enable BFD support for IS-IS by enabling it globally on all IS-IS interfaces or by enabling it on one
or more interfaces.
Configuring BFD for IS-IS Globally
Beginning in privileged EXEC mode, follow these steps to configure IS-IS BFD globally, and to
optionally disable it on specific interfaces:
Command
Step 1 configure terminal
Step 2 router is-is area-tag
OL-9639-07
Purpose
Enter global configuration mode.
Specify an OSPF process, and enter router configuration mode.
Return to global configuration mode.
Specify an interface, and enter interface configuration mode.
Enable BFD on the specified OSPF interface. Repeat Steps 3 and 4 for all
OSPF interfaces on which you want to run BFD sessions.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Specify an IS-IS process and enter router configuration mode.
