Hi Folks,
I have some doubts about designing a topology for VPN.
I have 2 6506-E Switches and three fiber optic rings for local branch offices. Each ring begins on one 6506-E Switch and ends into the other 6506-E Switch. I have ASAs 5505 in each brach office and now I have to design the network in order to encrypt the data between branch offices and the main one.
I don't have enough budget to adquire the module for VPNs.
I need to know the pros and cons of the following possibilities:
- to adquire VPN concentrators in the main office
- to establish the VPN with existing routers (with encryption module)
- to establish the VPN with dedicated ASAs to concentrate them
- another solution??
Thanks in advance for your help.
Regards,
TITO
