This read-create integer configures the interval, in seconds, between LDP keepalive messages sent on this interface once an LDP session is established. Keepalives maintain an active LDP session between peers, so this interval determines how much steady-state signaling overhead the session generates and how quickly a dead peer can be suspected. An administrator on a high-session-count route reflector might lengthen csLdpEntityKeepAliveTimer to reduce keepalive overhead across many simultaneous LDP sessions.
