DHCP local server dual-stack subscribers are supported on a single VLAN session. This reduces the required number of session database (SDB) entries utilized and simplifies RADIUS authentication and accounting operations. The benefits of a single-session dual-stack model are as follows 

• Simplifies router configuration. 
• Reduces RADIUS message load. 
• Reduces the backend correlation of multiple accounting sessions for the same household. 
• Is Compatible with existing RADIUS messaging.
