RADIUS over IPv6 for system AAA

RADIUS functionality is supported over IPv6 for system authentication, authorization, and accounting (AAA). With this feature, users can log in to the router authenticated through RADIUS over an IPv6 network. To accept the IPv6 source address, include the source-address-inet6 statement at the [edit system radius-server IPv6] hierarchy level. (Note that if an IPv6 RADIUS server is configured without any source-address-inet6, then default ::0 is considered as the source address.)
