The CA server can be a third-party CA or one generated from a Cisco IOS certificate server. The Cisco IOS certificate server provides a certificate generation option to users who do not have a third-party CA in their network. The Cisco IOS certificate server can run on the SRST router or on a different Cisco IOS router. If you do not have a third-party CA, full instructions on enabling and configuring a CA server can be found in the Cisco IOS Certificate Server documentation. A sample configuration is provided below.
