Number of VPN Peers

[reinke]

Are there any advices limiting the number of vpn peers supported by a cisco 3660 router?

Or is the answer <it depends on ...>

... the bandwidth of the interface terminating the vpn peers

... the amount of DRAM

... the use of a harware encryption module???

Are there any pros to use a vpn concentrator instead of the 3660 router?

Thanks in advance

The answer is very much 'it depends' on all these thing plus the amount of traffic which is expected.

Using a VPN concentrator would be easier to configure as it has the web interface specifically for VPN but, using the router, you would get more flexibility, other IOS features etc.

Can't answer on the 3600 series. We were running about 15 VPN connections through a 2621 (SDSL link) at one point as a proof of concept test. We have since moved to a 7206VXR (50+ connections).

The 2621 had 64MB ram and a VPN-Basic encryption module. When we first started our proof of concept, we would run about 90% utilization on the router. We got it down to around 20% normal, 70%+ at peak.
