my cisco router uses a PKI certificate. the certificate used has an expiration date. the router is set to renew automatically (auto-enrollment) the certificate on a specified date (before the expiration date).
problem: when the router can not renew the certificate (obtain a new certificate) for any reason, It deletes the old certificate.
someone has an idea on this?
someone knows where I can find documents that describe the certificate renewal process by routers?
thank you for your help
