The above command assigns a multiplier value of 5 to bfd-vlan-101.
Enabling or Disabling BFD Status
As BFD is globally disabled for the routing instance, to enable the global BFD status, use the ip bfd
admin-state command. For example:
-> ip bfd admin-state enable
To disable the global BFD status for the routing instance, use the ip bfd admin-state command with the
disable keyword. For example:
-> ip bfd admin-state disable
The above command disables BFD globally on the routing instance. Note that disabling BFD does not
remove the existing BFD configuration from the routing instance. Also, when BFD is globally disabled, all
BFD functionality is disabled for the routing instance, but configuring BFD is still allowed.
To enable a BFD session, use the ip bfd interface admin-state command. For example:
-> ip bfd interface bfd-vlan-101 admin-state enable
The above command enables the administrative status of bfd-vlan-101.
Note that a BFD session must be disabled before any of its parameters can be changed. To disable a BFD
session, use the ip bfd interface status
command with the disable keyword. For example:
-> ip bfd interface bfd-vlan-101 admin-state disable
To verify the BFD status and configuration for the switch, use the show ip bfd command,. For example:
-> show ip bfd
BFD Version Number = 1,
Admin Status = Enabled,
Desired Tranmit Interval = 300,
Minimum Receive Interval = 300,
Detection Time Multiplier = 3,
Minimum Echo Receive Interval = 300,
Applications Registered = STATIC-ROUTING OSPF
The above command shows that BFD is registered with the OSPF protocol and has a transmit interval of
300 msecs, receive interval of 300 msecs, multiplier 3, and echo interval of 300 msecs.
To verify the BFD status and configuration, use the show ip bfd interfaces command. For example:
-> show ip bfd interfaces
Interface Admin Tx Min Rx Min EchoRx Detect OperStatus
Name Status Interval Interval Interval Multiplier
---------+--------+---------+---------+----------+----------+----------
one enabled 300 300 300 3 UP
two enabled 300 300 300 3 UP
The output above displays the interfaces participating in the BFD sessions, along with their IP interface
names and respective BFD session parameters. To see additional detail for a specific interface, use the
show ip bfd interfaces command and specify an interface name. For example:
-> show ip bfd interfaces one
Interface Name = one,
