next-hop (Dynamic Access Routes)

Syntax

Hierarchy Level

Description

Dynamically configure the next-hop address for an access route. Access routes are typically unnumbered interfaces.

The next-hop gateway can be specified explicitly in the framed route, as either the subscriber’s fixed address (common for business subscribers) or 0.0.0.0. Alternatively, the absence of the gateway address implies address 0.0.0.0. The address 0.0.0.0, whether implicit or explicitly configured, resolves to the subscriber’s assigned address (host route).

If the RADIUS Framed-Route attribute (22) or Framed-IPv6-Route attribute [99] does not specify the next-hop gateway—as is common—the variable representing the next-hop automatically resolves to the subscriber’s IP address.

Options

next-hop—Either the specific next-hop address you want to assign to the access route or one of the following next-hop address predefined variables.

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