[c-nsp] multipoint VPN options

[Stephen Kratzer]

All,

What options are available for a multipoint VPN for a customer with multiple 
connections via a dot1q-encapsulated VLAN back to a 7200 PE router? Would 
like to be able to offer a choice of layer 2 or layer 3, but the 7200 
platform may dictate. Things to consider:

- we're not running MPLS, but we could
- no requirements for layer 2 yet, but it would be nice to offer
- pretty sure the 7200s don't support VPLS
- no requirements for encryption yet, but it would be nice to offer on top of 
whatever VPN architecture is used
- not sure yet if they'll want to do dynamic routing across the VPN

Thanks,
