Configuring BFD for the specified protocol
25
Configuring BFD for the specified protocol
BFD can be configured for use with the following protocols:
OSPFv2
OSPFv3
IS-IS
BGP4
BGP4+
NOTE
BFD is not supported for OSPF v2 or v3 virtual links.
NOTE
BFD brings IS-IS and OSPF down with it when RSTP path-cost changes are made to the switch Alt
Discarding port.
Configuring BFD for OSPFv2
You can configure your device for BFD on the OSPFv2 protocol for all OSPFv2 enabled interfaces or
for specific interfaces as shown in the following sections.
Enabling BFD for OSPFv2 for all interfaces
You can configure BFD for OSPFv2 on all of a device’s OSPFv2 enabled interfaces using the
command shown in the following”
Brocade# router ospf
Brocade(config-ospf-router)# bfd all-interfaces
Syntax: [no] bfd all-interfaces
Although this command configures BFD for OSPFv2 on all of the OSPFv2 enabled interfaces for a
device, it is not required if you use the ip ospf bfd command to configure specific interfaces. It can
be used independently or together with the ip ospf bfd command.
Enabling or disabling BFD for OSPFv2 for a specific interface
You can selectively enable or disable BFD on any OSPFv2 interface as shown.
Brocade(config-if-e1000-3/1)# ip ospf bfd disable
Syntax: ip ospf bfd [disable]
The disable option disables BFD for OSPF on the interface.
Holdover interval
The BFD holdover interval is supported for single hop sessions. It sets the time by which the BFD
session DOWN notification to OSPF is delayed. If within that holdover time, the BFD session is UP
then OSPF is not notified of the BFD session flap.
The holdover interval can be configured globally.
