Configuring BFD
-> ip bfd interface vlan-10
-> ip bfd interface vlan-10 admin-state enable
Router 2
-> ip bfd interface vlan-12
-> ip bfd interface vlan-12 admin-state enable
-> ip bfd interface vlan-23
-> ip bfd interface vlan-23 admin-state enable
-> ip bfd interface vlan-20
-> ip bfd interface vlan-20 admin-state enable
Router 3
-> ip bfd interface vlan-23
-> ip bfd interface vlan-23 admin-state enable
-> ip bfd interface vlan-31
-> ip bfd interface vlan-31 admin-state enable
-> ip bfd interface vlan-30
-> ip bfd interface vlan-30 admin-state enable
Step 6: (Optional) Configure Global BFD Parameters
Global BFD parameter settings for timer values and operational mode are applied to all BFD interfaces
configured on the routing instance. When a BFD interface is created, the global settings are also applied as
the default parameter values for the interface.
The following steps change the default global BFD parameter values for the example network; the
commands used are the same on each router.
•
Set the minimum amount of time BFD waits between each transmission of control packets to 200.
-> ip bfd transmit 200
•
Set the minimum amount of time BFD waits to receive control packets to 200 milliseconds.
-> ip bfd receive 200
•
Set the global BFD Echo packet time interval to 200 milliseconds.
-> ip bfd echo-interval 200
Step 7: Enable BFD and register OSPF with BFD
Once all the global BFD parameters are configured, enable BFD on all interfaces, register BFD with
OSPF, and then enable BFD on all OSPF interfaces. The following steps are the same on each router:
'In this example, global BFD parameters will be used for the BFD sessions. Enable BFD admin status and
register OSPF with BFD and then enable BFD on all OSPF interfaces. Repeat the following steps on each
router:
-> ip bfd admin-state enable
-> ip ospf bfd-state enable
-> ip ospf bfd-state all-interfaces enable
