Cisco Pix - Multiple peers per crypto map sequence...

?
Hi,
 
I've got a tricky question:
Our situation is such that we've got several remote sites with Pix' and three 
interconnected main-sites each with an internet connection. We have the pix' 
dynamically set-up tunnels to our main site and in our crypto map we list all 3 
of our main-site's IP addresses as vpn peers. All 3 have been configured in an 
identical manner (same isakmp pol, access-lists, ...) (I know I checked 
exchaustively).
remote site example config:
crypto map xxxmap 10 ipsec-isakmp
crypto map xxxmap 10 match address aclmainsites
crypto map xxxmap 10 set peer A.B.C.D
crypto map xxxmap 10 set peer E.F.G.H
crypto map xxxmap 10 set peer I.J.K.L
crypto map xxxmap 10 set transform-set xxxset
crypto map xxxmap 10 set security-association lifetime seconds 3600 kilobytes 
4608000
crypto map xxxmap interface outside

Now my question :) : Only in the worst case scenario can the remote sites 
connect to the main-site I.J.K.L (because of limited Internet bandwith on this 
site), so how can I be sure that the sequence in which the remote pix 
establishes tunnels is such as I defined ??? I checked with cisco bu they have 
no docs on this. Nor do any of my usual forums... any input would be greatly 
apreciated.

 

Kind regards,
