I have 3 locations, 3 different network what is the best way to get
all 3 sites to see each other?

So far Im using ipsec  like this;     net3
                                                    /       \
                                                 net1    net2

then once that is done i was thinking to route the traffice from net1
to net2 thru net3 and net2 goes through net3 to get to net1.

I guess i could get connect net1 and net together via ipsec.
