You can configure the intervals that a
device waits to send (transmit) or receive control packets from Bidirectional Forwarding
Detection (BFD) peers.
About this task
BFD is enabled by default on configured
Layer 3 interfaces (IPv4 or IPv6). Take the following steps to configure the BFD session
parameters.
Procedure
-
Access global configuration
mode.
device# configure terminal
-
Access interface configuration
mode.
device(config)# interface ethernet 1/4
-
Specify the transmit time in milliseconds (ms), the receive time in ms, and the
multiplier value that determines the number of consecutive control packets that
must be missed before the connection to a peer is considered non-operational.
device(conf-if-eth-1/4)# bfd interval 100 min-rx 100 multiplier 10
This example specifies a transmit interval of 100 ms, the min-rx keyword followed by a receive interval
of 100 ms, and the multiplier value of 10, which indicates that 10 consecutive
packets must be missed before the connection to the peer is considered
non-operational.
Example
This example configures BFD session parameters
on a VE interface.
device# configure terminal
device(config)# interface ve 24
device(config-if-ve-24)# bfd interval 140 min-rx 125 multiplier 44
