Quality of Service for Voice over IP Fragmentation and Interleaving 13 QoSVoIP.mif MLP Link Fragmentation and Interleaving Example The following configuration example shows how to configure fragmentation and interleaving using MLP LFI: Frame Relay Fragmentation (FRF.12) On Frame Relay PVCs, the frame-relay traffic-shaping interface configuration command must be enabled and a fragmentation size set under the map class. Packets are fragmented on one end of PVC and reassembled at the other. Only available on Frame Relay PVCs with the frame-relay traffic-shaping interface configuration command enabled. Table 3 Link Speed and Fragmentation Size (continued) LFI Mechanism Description Benefits Limitations Configuration Example 6: MLP LFI interface Serial1/0 bandwidth 256 encapsulation ppp no fair-queue ppp multilink multilink-group 1 ! interface Multilink1 ip address 10.1.1.1 255.255.255.252 bandwidth 256 ppp multilink ppp multilink fragment-delay 10 ppp multilink interleave multilink-group 1 In this example, MLP LFI is configured with a fragmentation size of 10 ms, which is calculated based on the bandwidth configured for the multilink interface. Serial interface 1/0 is placed into multilink group 1 and therefore inherits the multilink configuration in the multilink 1 interface.
