Configuring BFD for the specified protocol
25
Enabling BFD for a specific BGP4 peer
To enable BFD for BGP4 for a specific neighbor or peer, enter a command such as the following
Brocade(config-bgp)# neighbor 10.14.1.1 fail-over bfd-enable
Syntax: [no] neighbor ipv4-address l ipv6-address fail-over bfd-enable
The ipv4-address | pv6-address variables specify the IPv4 or IPv6 address of a particular neighbor
or peer.
The no option removes the BFD for BGP4 peer from the configuration.
Disabling BFD for a specific BGP4 peer
To disable BFD for BGP4 for a specific peer, enter a command such as the following.
Brocade(config-bgp)# neighbor 10.14.1.1 fail-over bfd-disable
Syntax: [no] neighbor ipv4-address l ipv6-address fail-over bfd-disable
The ipv4-address l ipv6-address variables specify the IPv4 or IPv6 address of a particular neighbor
or peer.
The no option removes the BFD specific peer from the configuration.
Enabling BFD timers for a specific BGP4 peer
To enable BFD timers for a specific neighbor or peer for BGP4, you must first configure the bfd
timers, and set the holdover interval by entering commands such as the following.
Brocade(config-bgp)# neighbor 10.14.1.1 bfd min-tx 500 min-rx 500 multiplier 5
Brocade(config-bgp)# bfd holdover-interval 20
Syntax: [no] neighbor ipv4-address l ipv6-address bfd min-tx transmit-time min-rx receive-time
multiplier
Syntax: [no] bfd holdover-interval time-seconds
The ipv4-address l ipv6-address variables specify the IPv4 or IPv6 address of a particular neighbor
or peer.
The time-seconds variable is a number between 0 and 30 seconds. The default is 0 seconds.
The transmit-time variable is the interval in milliseconds between which this device will send a BFD
message to its peer informing it that it is still operational. Acceptable values are 50 - 30000. The
default value is 1000 (unless changed at the global level).
The receive-time variable is the interval in milliseconds that this device waits to receive a BFD
message from its peer. The device will wait for this interval for the number of times specified in the
number variable before determining that the connection to its peer is not operational. Acceptable
values are 50 - 30000. The default value is 1000 (unless changed at the global level).
The multiplier option allows you to specify a value for the number of times in a single sequence that
this device will wait to receive a BFD message from its peer before determining that the connection
to that peer is not operational. This value is set at the number variable. Acceptable values are 3 -
50. The default value is 3.
The no option removes the BFD for BGP configuration for the peer.
