Dynamic profile enhancements to support migration of static, terminated IPv4 PPP subscribers

The following enhancements support dynamic profiles for static subscribers:

• CPE-sourced subscriber address-You can direct jpppd to use the IP address supplied by the client in an incoming IPCP configure-request message rather than assigning another address by configuring your RADIUS server to Framed-IP-Address attribute (8) with the wildcard value of 255.255.255.255.
• Tag2 for static routes-For PPP subscribers that use static routes with a tag2 attribute for MP-BGP, you can configure your RADIUS server to include the tag2 attribute in the Framed-Route attribute [22] when it authenticates a subscriber. Alternatively, you can configure the dynamic profile to provide a specific tag2 value for a specific access route prefix.
• Local authentication-For clients that do not support authentication protocols such as PAP and CHAP, you can configure usernames and passwords locally. You can define the name based on one or more of the following: MAC address, agent circuit identifier, agent remote identifier, and domain name. The router uses these values when it contacts the RADIUS server for authentication.
