[c-nsp] Mass GRE termination

[Peter Hicks]

All,

I'm looking at a network topology with 3,000+ Cisco 877W routers in disparate 
locations.  WAN connectivity to a central site already exists and the 877 
provides access to the corporate network at each site.

I want to tunnel all wireless traffic to an aggregation server in the central 
site, ideally at Layer 2, and hand it off to a third party who will provide 
value-added services.

My first thought was to use VRFs and transport wireless traffic through our 
network to the aggregation site over GRE tunnels - however L2TP may scale 
better and be more 'stateful' than a GRE tunnel.

Does anyone have thoughts how this will work in practice?  I am faced with a 
more-or-less blank sheet of paper at the moment :)


Peter.
