ospfv3 bfd enable
Use
ospfv3 bfd enable
to enable BFD on an OSPFv3 interface.
Use
undo
ospfv3
bfd enable
to disable BFD on an OSPFv3 interface.
Syntax
ospfv3 bfd enable
[
instance
instance-id
]
undo
ospfv3 bfd enable
[

]
Default
BFD for OSPFv3 is disabled.
Views
Interface view
Predefined user roles
network-admin
Parameters
instance-id
: Specifies an instance by its ID in the range of 0 to 255. The default is 0.
Usage guidelines
BFD provides a mechanism to quickly detect the connectivity of links between OSPFv3 neighbors,
improving the convergence speed of OSPFv3.
OSPFv3 uses BFD to implement bidirectional control detection.
Examples
# Enable BFD on VLAN-interface 11 in instance 1.
<Sysname> system-view
[Sysname] interface vlan-interface 11
[Sysname-Vlan-interface11] ospfv3 bfd enable instance 1
ospfv3 cost
Use
ospfv3 cost
to configure an OSPFv3 cost for an interface in an instance.
Use
undo ospfv3 cost
to restore the default.
Syntax
ospfv3 cost
value
[
instance
instance-id
]
undo ospfv3 cost
[
instance
instance-id
]
Default
The cost is 1 for a VLAN interface, is 0 for a loopback interface, and is computed according to the
interface bandwidth for other interfaces.
