Configuring Dynamic Access Routes for Subscriber Management

You can dynamically configure access routes for DHCP and PPP subscribers based on the values specified in the following RADIUS attributes:

• For IPv4 access routes, use the variable, $junos-framed-route-ip-address-prefix. The route prefix variable is dynamically replaced with the value in Framed-Route RADIUS attribute [22].
• For IPv6 access routes, use the variable, $junos-framed-route-ipv6-address-prefix. The variable is dynamically replaced with the value in Framed-IPv6-Route RADIUS attribute [99].

To dynamically configure access routes:

1. Configure the route prefix for the access route as a variable.

   For IPv4:

   [edit dynamic-profiles profile-name routing-options]user@host# edit access route $junos-framed-route-ip-address-prefix

   For IPv6:

   [edit dynamic-profiles profile-name routing-options]user@host# edit access route $junos-framed-route-ipv6-address-prefix
2. Configure the next-hop address as a variable.

   For IPv4:

   [edit dynamic-profiles profile-name routing-options access route “$junos-framed-route-ip-address-prefix”]user@host# set next-hop $junos-framed-route-nexthop

   For IPv6:

   [edit dynamic-profiles profile-name routing-options access route “$junos-framed-route-ipv6-address-prefix”]user@host# set next-hop $junos-framed-route-ipv6-nexthop
3. Configure the metric as a variable (IPv4 only).
   [edit dynamic-profiles profile-name routing-options access route “$junos-framed-route-ip-address-prefix”]user@host# set metric $junos-framed-route-cost
4. Configure the preference as a variable (IPv4 only).
   [edit dynamic-profiles profile-name routing-options access route “$junos-framed-route-ip-address-prefix”]user@host# set preference $junos-framed-route-distance
5. Configure the tag as a variable (IPv4 only).
   [edit dynamic-profiles profile-name routing-options access route “$junos-framed-route-ip-address-prefix”]user@host# set tag $junos-framed-route-tag
