Configuration Tasks

MLFR configuration consists of three major tasks, each with several steps:

1. Create the member links to be aggregated into a multilink bundle.
   1. Specify the interface on which you want to configure MLFR.
      host1(config)#interface serial 2/0:1
   2. Specify MLFR as the encapsulation method on the interface.
      host1(config-if)#encapsulation mlframe-relay ietf
2. Add member links to a multilink bundle.
   1. Define the MLFR bundle.
      host1(config)#interface mlframe-relay boston
   2. Add each member link.
      host1(config-if)#member-interface serial 2/0:1
   3. (Optional) Add a description to the major interface.
      host1(config-if)#frame-relay description bostonBundleDescription
   4. (Optional) Configure Frame Relay parameters.
      host1(config-if)#frame-relay intf-type dce host1(config-if)#frame-relay lmi-type cisco
3. Configure the Frame Relay subinterface.
   1. Define the subinterface for the MLFR bundle.
      host1(config)#interface mlframe-relay boston.1
   2. Assign a DLCI for the subinterface.
      host1(config-subif)#frame-relay interface-dlci 16 ietf
   3. (Optional) Add a description to the subinterface.
      host1(config-subif)#frame-relay description bostonBundleSubOneDescription
   4. Assign an IP address to the subinterface.
      host1(config-subif)#ip address 10.10.100.1 255.255.255.0
   5. Assign an IPv6 address to the subinterface.
      host1(config-subif)#ipv6 address 1::1/64

Configuration Example

The following commands configure three T1 lines and aggregate them into a multilink bundle named boston.

Configuring Frame Relay Versus MLFR

All the configuration commands that apply to Frame Relay also apply to MLFR. The following listing describes commands specific to configuring MLFR; for other Frame Relay commands, see Configuring Frame Relay.
