And the cisco 899G: http://www.cisco.com/c/en/us/products/collateral/routers/800-series-routers/datasheet_c78-732744.html It is becoming an increasingly standard method of redundant communications to a site. The routers that the EHWIC module go into are commonly used in enterprise MPLS edge deployments. On Fri, Nov 6, 2015 at 7:46 AM, Adam Moffett <[email protected]> wrote: > It's not that.
