Hi Jordan,

Yes, the number displayed in [] behind the connection name uniquely
identifies an IKE_SA within the entire IKE_SA list.

> Is the instance ID unique with in the entire IPsec SA list?

Yes, the number displayed in {} here is actually the reqid of an IPsec
SA, that is, it can also be seen in the output of ip xfrm state.

> I want to use the instance # (without connection name) to delete IKE_SA

Simply use either [n] or {n} with ipsec down to do that (n being the
respective unique id).  That the name is optional in this case is now
also explained on the wiki page at [1].
