A row in this table contains backoff information about an
LDP adjacency.
When an LDP session startup fails for the first time, the
LDP entity waits for a certain time interval before it tries
to setup the session again. This interval is the backoff
interval. The initial value for the backoff interval is set
to the value of vRtrLdpAdjInitBackoff. After waiting for the
backoff interval, LDP retries to setup the LDP session. If
it fails again the backoff interval increases exponentially
and this repeats for each successive LDP session startup
failure. If the backoff interval exceeds vRtrLdpAdjMaxBackoff,
LDP will not backoff anymore and will give up trying to
establish the LDP session.
