Basically I'm tasked with turning my 40 site layer 2 network (T1 layer 2 connectivity per site) into a routed layer 3 network as I currently have issues with broadcasts saturating the links plus the network is open to my service provider as there is no encryption on the linksâ¦ I'm simply only thinking of two things at the moment as my budget is extremely tight:
1> Eliminate broadcast by replacing the fully switched network with a routed network
2> Data Security (VPN connections back to the main office)
VOIP would be very beneficial to us at the moment but we simply can't afford it now and we are also locked into a contract with our Telecom provider (PSTN services) that runs for another year and a half.
What should I do? I'm thinking of purchasing the 861 routers (security bundle) for the 40+ sites and connect them back to my main office (which also has a 2821 security bundle) through a VPN.
This would eliminate the two issues I stated above but the other problem is integrating VOIP services into the network a year or so from now, I simply don't want to remove and replace all these routers come mid 2010 or soâ¦ We tried to convince management to go VOIP but our IT budget is being slashed at almost every second with this economic storm at handâ¦ How do you build a future proof network on a limited budget :-) ? Let me know your thoughtsâ¦.
