Hi, just recieved some new Cisco 2901 routers (replacing older 2811's). It came with c2900-universalk9-mz.SPA.154-3.M1.bin loaded on. Is this the best IOS for this router? There is one newer one but its an early deployment release. There is an older one that is in maintenance release 4.
Not doing anything crazy with these things. Just simple routing branch offices to a HQ location using a 10mbps wan or 4g lte if the 10mbps wan goes down.
