Configuring Dynamic Access-Internal Routes for PPP Subscriber Management
You can dynamically configure access-internal routes for PPP subscribers. Configuring support for access-internal variables is optional, but it ensures that values from the access-internal variables are used if the next-hop value is missing in the relevant RADIUS attribute—Framed-Route [22] for IPv4 and Framed-IPv6-Route [99] for IPv6.
 | Best Practice: We recommend that you always include the access-internal stanza in the dynamic-profile when the access stanza is present for framed route support. |
For PPP subscriber interfaces, you do not need to specify the MAC address for access-internal routes.
To dynamically configure access-internal routes for PPP:
- Specify that you want to configure the access-internal
route.user@host# edit dynamic-profiles profile-name routing-options
- Specify the IP address as a variable.[edit dynamic-profiles profile-name routing-options]user@host# edit access-internal route $junos-subscriber-ip-address
- Specify the qualified-next-hop as a variable.[edit dynamic-profiles profile-name routing-options access-internal route $junos-subscriber-ip-address]user@host# set qualified-next-hop $junos-interface-name
