If I have setup my RSVP refresh time to be 30 secs then all my path and
resvs should be refreshed approx. every 30 secs. But when I scale a box to
setup 2000 lsps with both Juniper and Cisco I see it not being refreshed
exactly at 30 secs but being done approx. within 45 secs.

This behaviour is not consistent with the theory that a node would wait
keep-multiplier * refresh time before deleting a session. In this case a
previous hop or nexthop would expire on missing just a single refresh packet
if keep-multiplier is 3.

Comments from Cisco/Juniper???
