IKE lifetime seconds

[James Comen <jcomen@torrentnet.com>]

When the ike protection suite lifetime is reached (either in time or kb),
the IKE sa is deleted.
I've seen nothing that suggests that it should be automatically renegotiated
like an ipsec SA.  I'm assuming that the IKE sa must be negotiated
again
via the receipt of a packet which requires ipsec protection.
Is this correct, that there should be no automatic renegotiation of
the IKE sa?
Thanks
Jim
