VPN between central router and three remote sites

I have to configure VPN with IPSec and 3DES between central router and three remote routers. This is the star topology, not fully meshed and remote offices want to have secure communication between each other. Do I have to create VPN first from one remote to central, and then from central to another remote? Any advice is appriciated.

Re: VPN between central router and three remote sites

If Remote site networks need to intercommunicate, separate interfaces (either physical or subordinate)- or GRE tunnels must be used in combination with IPsec on the IOS Hub router in order to terminate the spoke tunnels and route packets between them. I would opt for the GRE configuration.
