PPP multilink Interleaving over Frame Relay ?

I try to get PPP multilink Interleaving over Frame Relay but cannot get "Interleaving Enable" . What i'm missing here ?


 

interface Serial2/0


 no ip address

 encapsulation frame-relay

!


interface Serial2/0.231 point-to-point



 frame-relay interface-dlci 231 ppp Virtual-Template1

end


!



interface Virtual-Template1

 bandwidth 128

 no ip address

 ppp multilink

 ppp multilink interleave

 ppp multilink group 1

 ppp multilink fragment delay 8

end




interface Multilink1

 bandwidth 128

 ip address 22.22.13.1 255.255.255.0

 fair-queue

 ppp multilink

 ppp multilink group 1

end



multilink virtual-template 1

Rack11R1(config-if)#do sh ppp multi

Multilink1

  Bundle name: Rack22R3

  Remote Endpoint Discriminator: [1] Rack22R3

  Local Endpoint Discriminator: [1] Rack11R1

  Bundle up for 00:12:21, total bandwidth 128, load 1/255

  Receive buffer limit 12000 bytes, frag timeout 1000 ms           //It doesn't show Interleaving enable ??

    0/0 fragments/bytes in reassembly list

    0 lost fragments, 0 reordered

    0/0 discarded fragments/bytes, 0 lost received

    0x0 received sequence, 0x0 sent sequence

  Member links: 1 active, 1 inactive (max not set, min not set)

    Vi1, since 00:12:21

    Vt1 (inactive)

No inactive multilink interfaces

What i'm missing here ? Is the sequence matter?

  • Hi.

    Do you have frame relay traffic shaping configured?

  • Hi!

    Maybe you forgot the "ip rtp reserve" command?

    Check here: (seems to be a required attribute) for the interleaving:

  • I expect "multilink virtual-template 1" copy virtual template config to multilink interface..

    but if for some reason doesn't so i have to put manually:




    interface Multilink1

     bandwidth 128

     ip address 22.22.13.1 255.255.255.0

     fair-queue                                                  //Must have !!

     ppp multilink

     ppp multilink group 1

     ppp multilink interleave                               // make sure it's copied or put it again manually

     ppp multilink fragment delay 8                    

    end






    R1#sh ppp multilink

    Multilink1

      Bundle name: R2

      Remote Endpoint Discriminator: [1] R2

      Local Endpoint Discriminator: [1] R1

      Bundle up for 00:00:02, total bandwidth 128, load 1/255

      Receive buffer limit 12000 bytes, frag timeout 1000 ms

      Interleaving enabled                                                                 /// it's good now :)

        0/0 fragments/bytes in reassembly list

        0 lost fragments, 0 reordered

        0/0 discarded fragments/bytes, 0 lost received

        0xA received sequence, 0xA sent sequence

      Member links: 1 active, 1 inactive (max not set, min not set)

        Vi1, since 00:00:02, 128 weight, 118 frag size

        Vt1 (inactive)

    No inactive multilink interfaces
