LDP peering went down for 6 seconds
I am willing to know; what role hello interval and KA interval play in declaring LDP peering down
and ehat holdtime is reponsible for?

LDP Hold time is the time the router waits before declaring the LDP session down.
a) Discovery hold timer
used during session establishment.
b) session hold timer
used once the TCP connection is established.
Hello time interval is the period LDP hello's are generated to discover the neighbors.
Keep alive interval is the period LDP keepalives are sent once the session is established b/w the neigbhors.
Hope this helps.

hello interval is 5sec. .... discovery holdtime is 15s
KA interval is 60s .... session holdtime is 180s
if a router missed 3 hello packets, he will declare its neighbour down
then KA will be sent every 60s; after missing 3 KA msgs the router will remove neighbour from his database
