If the username contains both a realm name and a domain name delimiter, you can use either the domain name or the realm name as the domain name. As previously mentioned, the router treats usernames with multiple delimiters as though the realm name is to the left of the realm delimiter and the domain name is to the right of the domain delimiter.
If you set the parse order to:
For example, if you set the delimiter for the realm name to / and set the delimiter for the domain name to @, the router parses the realm first by default. The username usEast/lori@abc.com results in a domain name of usEast. To cause the parsing to return abc.com as the domain, enter the aaa parse-order domain-first command.
