Access and Access-Internal Routes for DHCP Subscriber Management
The DHCP application on a video services router uses both access routes and access-internal routes to represent either the end users or the networks behind the attached router. An access route represents a network behind an attached video services router, and is set to a preference of 13. An access-internal route is a /32 route that represents a directly attached end user, and is set to a preference of 12.
You can dynamically configure access routes using values specified in Framed-Route Attribute [22]. Configuring support for access-internal variables is optional, but it ensures that if the next-hop value is missing in the Framed-Routes Attribute [22], values from the access-internal variables are used instead.
