� The LDP session backoff reestablishment mechanism prevents
two LSRs with incompatible configurations falling into the end-
less cycle form the establishment of the session to the fail-
ure. If the establishment of the session fails because of the
incompatible configurations of the two LSRs, the two LSRs will
put off their attempt to establish a session next time (namely
back off). The backoff time is exponentially increased until it
reaches the maximum backoff.
� The default value of the parameter of the LDP session back-
off reestablishment mechanism is defined by the LDP protocol
specifications. There is no need to change tyhe default config-
uration until the default parameter indeed causes bad behav-
iors.
This example describes how to set the initial backoff time as 30
seconds and the maximum backoff time as 240 seconds.

mpls ldp bfd

Use this command to configure the corresponding parameters of
LDP LSP BFD and trigger the bfd session for creating LSP.

This command triggers the creation of LSP BFD, and specifies the
network address of LSP.
This example describes how to triggers the creation of BFD of LSP
2.2.2.2.
ZXR10(config)#mpls ldp bfd 2.2.2.2 32 interval 50
min_rx 50 multiplier 3
Specifies the LSP address for creating bfd. It
is generally a remote address network
Specifies the sub network mask length of
remote address. range: 1~32
Specifies the minimal sending interval, in
milliseconds. range: 50~999
Specifies the minimal receiving interval, in
milliseconds. range: 50~999
Specifies the multiplier when the detection
overtimes. range: 3~50
