IPSEC/ISAKMP VPN on Cisco 3900

[esamaniego]

I just replaced 2800 router this did not have a VPN hardware accelerator with a 3925 that does have a VPN accelerator built in. I copied the same VPN (ISPEC/ISAKMP) config from the 2800 to the 3925 and it works.

Here is my question, is there something special I have to do to enable the hardware acceleration or is it automatically used for every VPN session?

Hi Erik,

It does not require any command to enable hardware acceleration and RTR procees the VPN traffic in hardware by default.

Thanks,
