Timer Description Usage
Exponential
backoff timer
Started by an LSR that plays an
active role after the LSR fails to
process an LDP Initialization
message or is notified that
another LSR playing a passive
role rejects parameters carried in
the received LDP Initialization
message. The LSR playing the
active role periodically resends
an LDP Initialization message to
initiate an LDP session before
the Exponential backoff timer
expires.
l The initial and maximum values
can be increased to allow a longer
interval between attempts to
establish an LDP session during
device upgrade.
l The initial and maximum values
can be reduced to allow a shorter
interval between attempts to
establish an LDP session if
intermittent service interruptions
occur.
Using default values of these timers are recommended.
