Hi Dinesh,

You can look at many router-to-router Ipsec configurations at:

thx a lot.

one more doubt.I m using the same two 7206 routers between the two sites for IPLC `s which asre forwarding my voice traffci between the two locations.I want to use the same 7206 VXR Routers at the two locations for VPN.

If i donot use any hardware module.Is it going to cause abny issues.

And what IOS version should i have on my routers.

Hi there,

Voice traffic is time sensitive. Having a router without an encryption module would add considerable delay when the packet gets encrypted. I guess, it really depends on you how much delay you can tolerate. You can look at the V3PN design guide for different scenarios and IOS recommendation etc
