Example: Configuring IP Subscribers on a Dynamic Bridged Ethernet Interface Using IP Subscriber Management

Requirements

• JunosE Release 7.1.0 or higher-numbered releases
• E Series router (ERX7xx models, ERX14xx models, the ERX310 router, the E120 router, or the E320 router)
• ASIC-based line modules that support Fast Ethernet or Gigabit Ethernet

Overview

In this configuration, the IP service profile provides the subscriber’s authentication parameters, and the subscriber management application is the authenticating layer. To assign the IP service profile to the interface profile, use the bridge1483 service-profile command.

For more information about using the subscriber management application, see JunosE Broadband Access Configuration Guide.

Configuring IP Subscribers on a Dynamic Bridged Ethernet Interface

Step-by-Step Procedure

1. Define an IP service profile.
   host1(config)#ip service-profile eastServiceProfile
2. Assign the subscriber’s username, domain, and password to the IP service profile.
   host1(config-service-profile)#user-name westford001 host1(config-service-profile)#domain xyzcorp.east host1(config-service-profile)#password abc123 host1(config-service-profile)#exit
3. Configure the interface profile from which to create a dynamic bridged Ethernet interface. For more information, see Dynamic Interface Configuration Using a Profile.
   host1(config)#profile east
4. Include the desired attributes for the profile (in this case, IGMP). For more information, see Configuring IPv4 Characteristics for a Profile.
   host1(config-profile)#ip igmp host1(config-profile)#ip igmp immediate-leave host1(config-profile)#ip igmp group limit 6
5. (Optional) Configure the name of the route map used to configure the IP subscriber interface.
   host1(config-profile)#ip route-map ip-subscriber eastRouteMap
6. Configure the name of the IP service profile containing the authentication parameters for the dynamic bridged Ethernet interface.
   host1(config-profile)#bridge1483 service-profile eastServiceProfile host1(config-profile)#exit
7. Configure the static ATM 1483 subinterface to assign the east profile.
   host1(config)#interface atm 2/1.100 point-to-point host1(config-subif)#profile bridgedEthernet east
8. Enable autodetection of the bridged Ethernet upper-layer encapsulation type. For more information, see Configuring a Dynamic Interface over an ATM 1483 Subinterface
   host1(config-subif)#auto-configure bridgedEthernet
9. Define the ATM PVC. For more information, see Creating a PVC on an ATM 1483 Subinterface
   host1(config-subif)#atm pvc 100 10 101 aal5snap 6400 0 0 host1(config-subif)#exit
