Create an MFR Bundle

A multilink bundle consists of a maximum of 8 T-1s or E1s. To create a multilink bundle, complete the

following steps:

Step 1 Enter MFR interface configuration mode:

Router# configure terminal

Router(config)# interface MFR 1

Step 2 Assign an IP address to the MFR interface:

Router(config-if)# ip address address mask

Router(config-if)#

Step 3 Assign a bundle ID

Router(config-if)# frame-relay multilink bid BUNDLE1

Step 4 Remaining frame-relay configuration is the same as for non-multilink interfaces

Assign an Interface to an MFR Bundle

To assign an interface to a multilink bundle, use the following commands in interface configuration

mode:

Step 1 Select the serial interface using the form of the interface serial command that is appropriate to your

configuration context:

Router(config)# interface serial slot/port.number

Step 2 Associate a serial interface with the MFR bundle:

Router(config)# encapsulation frame-relay MFR1

Router(config)#

Link Fragmentation Reassembly Configuration

Link Fragmentation Reassembly (LFI) allows the router to send large, low priority packets and small,

high priority packets on the same DLCI while minimizing the latency of high priority packets. The low

priority packets are fragmented and high-priority packets are inserted between the fragments of the low

priority packets. The configuration must include the following steps:

1 2 ... 38 39 40 41 42 43 44 45 46 47 48 ... 57 58
