+ + 5.2 + Configuring Frame Relay 
  + 5.2.4 + Frame Relay subinterfaces 
+ + + + + + +
+ +

+ + To enable the forwarding of broadcast routing updates in a hub-and-spoke + Frame Relay topology, configure the hub router with logically assigned + interfaces. These interfaces are called subinterfaces. Subinterfaces are logical subdivisions of + a physical interface. +

+ + In split-horizon routing environments, routing updates received on one + subinterface can be sent out another subinterface. In a subinterface + configuration, each virtual circuit can be configured as a point-to-point + connection. This allows each subinterface to act similarly to a leased + line. Using a Frame Relay point-to-point subinterface, each pair of the + point-to-point routers is on its own subnet.

+ + Frame Relay subinterfaces can be configured in either point-to-point or + multipoint mode:

    +
  • + + Point-to-point – A single point-to-point subinterface is used to establish + one PVC connection to another physical interface or subinterface on a remote + router. In this case, each pair of the point-to-point routers is on its own + subnet and each point-to-point subinterface would have a single DLCI. In a + point-to-point environment, each subinterface is acting like a + point-to-point interface. Therefore, routing update traffic is not subject + to the split-horizon rule.
    • +
  • + + Multipoint – A single multipoint subinterface is used to establish multiple + PVC connections to multiple physical interfaces or subinterfaces on remote + routers. All the participating interfaces would be in the same subnet. The + subinterface acts like an NBMA Frame Relay interface so routing update + traffic is subject to the split-horizon rule.
    • +
+ +

+ + The + + encapsulation frame-relay + + command is assigned to the physical interface. + All other configuration items, such as the network layer address and DLCIs, + are assigned to the subinterface.

+

+ Multipoint configurations can be used to conserve addresses that can be + especially helpful if Variable Length Subnet Masking (VLSM) is not being + used. However, multipoint configurations may not work properly given the + broadcast traffic and split-horizon considerations. The + point-to-point subinterface option was created to avoid these issues.
