Subject: draft-ietf-ipv6-2461bis-02.txt - randomizing reachable time

Hi,
I have a question regarding 6.3.4 in the above 
neigbour-discovery draft.
On page 49 it is stated, that if reachable time is
not updated by new router advertisements, a host
SHOULD recompute a new random reachable time value every few hours.
Can anybody tell me why a host should do this ?
- whats the advantage ?
Best regards
   Peter
