For information about configuring QoS, see JUNOSe Quality of Service Configuration
Guide.
Configuring Policy Management
Policy management allows network service providers to implement packet forwarding
and routing specifically tailored to their customer’s requirements. Using policy
management, customers can implement policies that selectively cause packets to
take different paths. Policy management provides several types of services:
■ Policy routing—Predefines packet flow to a destination port or IP address
■ QoS classification and marking—Marks packets of a packet flow.
■ Packet forwarding—Allows forwarding of a packet flow.
■ Packet filtering—Drops packets of a packet flow.
■ Packet logging—Logs packets of a packet flow.
■ Rate limiting—Enforces line rates below the physical line rate of the port and
sets limits on packet flows.
■ RADIUS policy support—Allows you to attached a preconfigured policy to an
interface through RADIUS.
See JUNOSe Policy Management Configuration Guide, for details about configuring
policy management.
Configuring Remote Access
The E Series router supports the following remote access functionality:
■ Broadband Remote Access Server (B-RAS)—This application runs on the router
and is responsible for:
■ Aggregating the output from DSLAMs
■ Providing user PPP sessions and PPP session termination
■ Enforcing QoS policies
■ Routing traffic into an ISP’s backbone network
See JUNOSe Broadband Access Configuration Guide.
■ Layer 2 Tunneling Protocol (L2TP)—A method of encapsulating layer 2 packets,
such as PPP, for transmission across a network. In an L2TP relationship, an L2TP
access concentrator (LAC) forms a client-server relationship with a destination,
known as an L2TP network server (LNS), on a remote network.
You can configure the router to act as an LAC in PPP pass-through mode. The
router creates tunnels dynamically by using AAA authentication parameters and
transmits L2TP packets to the LNS through IP/UDP. See JUNOSe Broadband Access
Configuration Guide.
■ Non-PPP equal access—A method of allowing remote access in which the router
provides IP addresses to subscribers’ computers through Dynamic Host
