Re: Vpn client - crypto isakmp client configuration group Missin
Yes, you are on the right track. The IOS that you are currently running on the router 12.2(17a) does not support GROUP Feature as well as VPN Client 3.x.
You need a minimum of 12.2(15)T2 to support VPN Client 3.x
Now, in your case:
1. You can upgrade to 12.2(15)T15. But this code is deferred and your option is to go 12.3 Mainline.
2. You can upgrade to a version in 12.3 Mainline and this should have all the features that were in 12.2T Train. So, you would get the Group Feature as well as VPN Client 3.x support.
Now, here comes the challenge. The Feature set that you have on the router is "IP PLUS IPSEC 3DES". So, if you go to 12.3(20) which is the latest and GD Version in 12.3 mainline, you need 32 MB Flash and 96 MB RAM. But, the the current memory on the router is only 64 MB, So you need to upgrade the router's memory from 64 MB to 96 MB and upgrade the router 12.3(20).
