To globally reset to zero the number of times that the Bidirectional Forwarding Detection (BFD) protocol
was dropped on an interface or the number of times that a link was down, use the clear ip rsvp hello bfd
command in user EXEC or privileged EXEC mode. To disable the resetting of those counters, use the no
form of this command.
clear ip rsvp hello bfd {lo
st-cnt | nbr-lost}
no clear ip rsvp hello bfd {l

Command History
Usage Guidelines When you unconfigure BFD-triggered Fast Reroute, the BFD session is not torn down. Enter the c
lear
ip rsvp hello bfd command to clear show command output for Multiprotocol Label Switching (MPLS)
traffic engineering (TE) features that use the BFD protocol.
The cl
ear ip rsvp hello bfd command globally resets to zero the LostCnt field in the show ip rsvp hello
bfd nbr summary command and the show ip rsvp hello bfd nbr command. Those fields show the
number of times that the BFD session was lost (dropped) on an interface.
The c
lear ip rsvp hello bfd command also resets to zero the Communication with neighbor lost field in
the show ip rsvp hello bfd nbr detail command. That field shows the number of times the BFD protocol
detected that a link was down.
Examples The following example resets to zero the Communication with neighbor lost field in the show
ip rsvp
hello bfd nbr detail command that shows the number of times the BFD protocol detected that a link was
down:
Router# clear ip rsvp hello bfd nbr-lost
lost-cnt Resets to zero the number of times that the BFD session was lost (dropped)
on an interface.
nbr-lost Resets to zero the number of times the BFD protocol detected that a link was
