Hi, in all cisco documentation I looked that the command "radiusradius-server key" is used to authenticate and encrypt all data transmited between router and Radius server but I didn´t find what protocol is used to provide encrypt of this data. I ask this because I´m trying to authenticate my routers behind I Radius installed in a Linux server and I only get it when I use plain text.
Re: encrypt protocol used by Radius authentication
"radius-server key" command is used by the radius server to authenticate the client. When a authenticatin request comes to radius server, radius server first validates sending the client. If the preshared keys of client and server don't match server simply drops the request. So that key is only used for authentication of client. In addition, any user passwords are sent encrypted between the client and RADIUS server.
