I have a cisco 2851 running IOS Version 12.4(11)T2 with CME 4.0(2).
I will be running a cisco 877w on the remote site.
What I am wondering is what are the best techniques to set this up?
Should I use a Remote access or a Site to Site type VPN solution?
What kind of tunnel setup should I configure? (PPTP, L2TP over IPSec, GRE, GRE over IPSec, pure IPSec)
I am assuming once the VPN is configured for IP connectivity between the remote site and main site that the phone setup will be the same as normal, as long as the phone has the correct TFTP ip address.
Hi, if you don't have special security concerns, I would use GRE in first place. That is easy to encipher with a crypto profile if the need arise. With a proper VPN you don't need to worry about where devices are and everything works transparently. You don't need to make vlans or try to bring the remote phone into local voice vlan, as it will work anyway.
Hi, with a gre setup, the remote site would receive routing information for all the vlans and viceversa. So you have three (ospf or rip) routers, the 877, the 2851 where tunnel lands, and the 3560.
The security consideration is if you want the traffic to be encrypted or not, really from the router point of view doesn't make much of a difference, but encryption it's more overhead on the circuits, that's all.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
