If I setup a VPN tunnel with a 100 Mbps ISP connection on both ends.  Is it safe to say my VPN tunnel link has a bandwidth capacity of 100 Mbps?  What are the pros and cons of using a VPN tunnel vs. using a MPLS link of smaller bandwidth capacity?

With the Cisco VPN you can loose up to 10-13% of your bandwidth for overhead.  MPLS is the way to go.  you are not limited in what you can send over the pipe and overhead is way less.  Most ISP/Phone companies switched to MPLS years ago as they can do long haul voice and data trunking over it without having to buy LD or data drains from tier 1 providers.

Hi,

HOW many is the MTU on the ISP, what type of VPN do you use?

We are most likely going to have Cisco ASA's on both ends.  The mtu on all interfaces are set to 1500
We are looking to use AES-256 bit encryption.
