Sundarum, I assume by "VPN" you mean IPSec. IPSec is supported beginning in 12.0 on the 2500 platform, but only for 56 bit DES. As far as I know, 3DES, or Triple DES, is not supported on the 2500 platform. This is probably due to the performance limitations of the 2500. The 2500 doesn't have a lot of horsepower, and the encryption/decryption process is very CPU intensive. If you plan to have a lot of encrypted traffic go through a 2500, your probably not going to be satisfied with the performance. There are encryption performance numbers somewhere on CCO, but I seem to recall that the 2500 maxed out at about 128kbps using encryption. FYI, if you want to know about a particular feature and if its supported on a platform and in what version, check out <http://www.cisco.com/go/fn> Regards, Kent On 5 Apr 2001, at 10:19, Arumugam Sundarum wrote: > Hi Ciscoians, > I have an existing 2500 ISDN router - IOS version 11 which I want to > use it for VPN tunneling.
