FR fragmentation configuration example

As shown in Figure 49, Router A connects to Router B through an FR network. Because many large-sized data packets pass through the FR network, the transmission delay is very high. To reduce transmission delays, enable FR fragmentation (FRF.12) on the two devices to fragment large-sized data packets into small data packets.

1. Configure Router A:

   # Create FR class test1, enable FR fragmentation, and set the fragment size to 128 bytes.

   <RouterA> system-view
   [RouterA] fr class test1
   [RouterA-fr-class-test1] fragment 128
   [RouterA-fr-class-test1] quit
   

   # Enable FR encapsulation and FRTS on interface Serial 2/0.

   [RouterA] interface serial 2/0
   [RouterA-Serial2/0] link-protocol fr
   [RouterA-Serial2/0] ip address 10.1.1.2 255.0.0.0
   [RouterA-Serial2/0] fr traffic-shaping
   

   # Create DLCI 16, and apply the FR class test1 to DLCI 16.

   [RouterA-Serial2/0] fr dlci 16
   [RouterA-fr-dlci-Serial2/0-16] fr-class test1
   

2. Configure Router B:

   # Create FR class test1, enable FR fragmentation, and set the fragment size to 128 bytes.

   <RouterB> system-view
   [RouterB] fr class test1
   [RouterB-fr-class-test1] fragment 128
   [RouterB-fr-class-test1] quit
   

   # Enable FR encapsulation and FRTS on interface Serial 2/0.

   [RouterB] interface serial 2/0
   [RouterB-Serial2/0] link-protocol fr
   [RouterB-Serial2/0] ip address 10.1.1.1 255.0.0.0
   [RouterB-Serial2/0] fr traffic-shaping
   

   # Create DLCI 16 and apply FR class test1 to DLCI 16.

   [RouterB-Serial2/0] fr dlci 16
   [RouterB-fr-dlci-Serial2/0-16] fr-class test1
