  • Page 34: Atm Interfaces

    JUNOSe 11.0.x Link Layer Configuration Guide ATM Interfaces An ATM port can have a major interface and one or more subinterfaces. An ATM subinterface is a mechanism that enables a single physical ATM interface to support multiple logical interfaces. Several logical interfaces can be associated with a single physical interface.
  • Page 35: Atm Virtual Connections

    Chapter 1: Configuring ATM Depending on the type of connection you choose, you can specify one or more PVCs on each interface. For a standard point-to-point ATM interface, you configure only one PVC. For NBMA ATM connections, you configure multiple circuits. ATM Virtual Connections A virtual connection (VC) defines a logical networking path between two endpoints in an ATM network.

    LLC/SNAP or VC-based multiplexing. (See “Configuring Dynamic Interfaces” on page 465.) aal5all Martini encapsulation NOTE: The Juniper Networks E120 and E320 Broadband Services Routers do not support Martini encapsulation (aal5all) in the current release. Local ATM Passthrough E Series routers support local ATM passthrough for ATM layer 2 services over Multiprotocol Label Switching (MPLS).
  • Page 37: Traffic Management

    Chapter 1: Configuring ATM For more information, see chapter Configuring Layer 2 Services over MPLS in JUNOSe BGP and MPLS Configuration Guide. NOTE: The E120 and E320 routers do not support ATM over MPLS with VCC cell relay encapsulation in the current release. Traffic Management The scheduling priority for traffic classes depends on the type of router that you have.
  • Page 38: Table 4: Traffic Parameters Used To Compute Bandwidth

    JUNOSe 11.0.x Link Layer Configuration Guide Table 4 on page 8 lists the traffic parameter that the router uses for each service category to compute the bandwidth that the connection requires. For example, the peak cell rate is used to calculate how much bandwidth is required for CBR connections.
  • Page 39: Ilmi

    VPI/VCI Address Ranges The VPI/VCI address ranges allowed on ATM interfaces are module dependent. Certain modules on ERX14xx models, ERX7xx models, or the Juniper Networks ERX310 Broadband Services Router have a fixed allocation scheme, whereas others have a configurable allocation scheme. In the configurable allocation scheme, a bit range is shared across the VPI and VCI fields.
  • Page 40: Vp Tunneling

    The level of support for VP tunneling is dependent on the specific I/O module. See “Supported Features” on page 12 for details. Platform Considerations You can configure ATM interfaces on the following Juniper Networks E Series Broadband Services Routers: E120 router...
  • Page 41: Interface Specifiers

    Chapter 1: Configuring ATM Interface Specifiers The configuration task examples in this chapter use the slot/port[.subinterface ] format to specify an ATM interface. However, the interface specifier format that you use depends on the router that you are using. For ERX7xx models, ERX14xx models, and ERX310 router, use the slot/port[.subinterface ] format.

    JUNOSe 11.0.x Link Layer Configuration Guide Figure 2: NBMA Interface Stack Unlike standard point-to-point ATM interfaces and broadcast-oriented Ethernet interfaces, NBMA interfaces form a point-to-multipoint connection. For example, you can use NBMA to connect a router to multiple stations. An NBMA interface consists of a single ATM 1483 subinterface that has two or more VCs.
  • Page 45: Removing Circuits

    Chapter 1: Configuring ATM removes entries that cannot be successfully refreshed after three successive failed InARP requests. Removing Circuits If a circuit is removed, it is also removed from the ARP table, but not from the static map. If the circuit is reconfigured, a new ARP table entry is generated from the existing map entry.

Remote defect indication (RDI) cells, which are received from the remote endpoint of the VP/VC and indicate an interruption in the cell transfer capability of the VP/VC.
  • Page 47: Continuity Verification

    Chapter 1: Configuring ATM Continuity Verification CC cells provide continual monitoring of a connection on a segment or end-to-end basis. To verify the integrity of the link, you can set up a VP or VC to regularly send or receive CC cells at either the segment level or at the end-to-end level. The CC cell source generates the CC cells, and the sink receives and processes the cells.
  • Page 48: After Cc Cell Flow Is Enabled

    JUNOSe 11.0.x Link Layer Configuration Guide After CC Cell Flow Is Enabled If the VC or VP is set up as the source point, the ATM interface sends one CC cell per second. CC cell generation stops if one of the following conditions occur: The ATM interface goes down.

  • Page 51: Rate Limiting For F5 Oam Cells

    Chapter 1: Configuring ATM Rate Limiting for F5 OAM Cells The router implements rate limiting for ATM F5 OAM cells to protect the corresponding ATM interface from denial-of-service (DoS) attacks. The interface discards control packets when the rate of control packets received exceeds the rate limit for ATM interfaces.

Equal-cost multipath (ECMP) is one way to achieve the desired bandwidth. MLPPP is commonly used as an alternative to ECMP to deliver NxT1 service.

When you enable multilink on your router, the router includes the MRRU option in LCP negotiation with the value set to the maximum received unit (MRU) value for PPP. If the remote system rejects this option, the local system determines that the remote system does not support multilink PPP and it terminates the link without negotiation.

    JUNOSe 11.0.x Link Layer Configuration Guide To ensure that the E Series router maintains the proper packet order when transmitting non-best-effort traffic, you can use the ppp hash-link-selection command to enable use of a hash-based algorithm to select the link on which the router transmits high-priority packets on an MLPPP interface.
