Can anyone give me a suggestion in the following.
We have a centralized WAN environment. 36XX-s are in the central site, 36pcs of 2610s are in the remote offices.
There's a 128Kbit leased line for every branch.
We are planning to run 3DES VPNs on every connection.
I know that I need HW vpn module in the central routers, but is it necessary in the remote 2610s?
These routers have very simple config, no jitter sensitive applications, just 128kbit data link.
Very simple and stable EIGRP network. No bells and whistles.
I and my Cisco SE are on different opinions. He sais the VPN module is necessary, I say it's not...
He sais the we should use HW VPNs for every site. That's 70-90k USD.
I tested it in our lab that the cpu usage goes up to 35-39% on a 2610 in this scenario sending large ftps from both directions. (full duplex 128kbit with large packets.) That seems acceptable.
And another thing, what about the faster 2610XM?
Thanks for the help,
