[Users] multiple security associations in ipsec6

hi
i was trying to create SA 's between two ipsec machines A & B having
following ipv6 addresses
A B
--- -----
3ffe::1 3ffe::1
3ffe::2 3ffe::2

i require SA's between all the combinations of addresses between the two
machines.
for e.g
Security association at A
--------------------------
SA1 src addr = 3ffe::1 dst addr = 3ffe::1

SA2 src addr = 3ffe::1 dst addr = 3ffe::2

SA3 src addr = 3ffe::2 dst addr = 3ffe::1

SA4 src addr = 3ffe::2 dst addr = 3ffe::2

Security association at B
--------------------------
SA1 src addr = 3ffe::1 dst addr = 3ffe::1

SA2 src addr = 3ffe::1 dst addr = 3ffe::2

SA3 src addr = 3ffe::2 dst addr = 3ffe::1

SA4 src addr = 3ffe::2 dst addr = 3ffe::2

but i can only create SA1 and SA4, or a tunnel mode SA between the same src
and destinations(in which case it rekeys the SA's created earlier for
transport mode). if i try to create any other SA it gives me the message
-internal error ,the route is already in use.
why does this happen when the eroute table has both the source and
destination addresses,and how can i over come this problem.
iam desperately in need of having SA;s with all address combinations. can
anyone pls help.

thanks and regards
