Storing Certificate to flash on Cisco Router

[davarg]

Does anyone know how to store\save a Certificate to a Cisco router?

I can retrieve the certificate with no problems and also use the certicate to connect my vpn tunnels. What I recently noticed is that after a reboot, the CA's certificate and information remains in the router config but the router's certicate is gone and I need to enroll again. I'm trying to avoid the enrolling because I don't want the CA on the internet at all.

I've gotten this to work with Pix Firewalls. That is, 1. put a certificate on the Pix (locally), 2. save the certificate to flash by using ca save all, 3. send the pix out to the field, 4. then pull up a vpn tunnel using the certificate (rsa-sig). There is never a problem with rebooting the pix.

oh by the way, I'm using an RSA Keon Certificate Authority if that helps. Also Cisco 2600, 1700, with IOS 12.2.X and higher.

Actually I think I found part of my answer. I may not have enough memory to store certificate locally. I guess need to verify my flash size? But there is no mention of minimum size to deal with certificates.
