Configuring Fragmentation and Reassembly for Static MLPPP

To configure fragmentation and reassembly on a static MLPPP link interface:

1. From Global Configuration mode, specify the individual link interface on which you want to configure fragmentation and reassembly.

   host1(config)#interface serial 4/0:1/1/1/1/1

2. Specify MLPPP as the encapsulation method on the link interface.

   host1(config-if)#encapsulation mlppp

3. Enable fragmentation on the link interface, and optionally specify the maximum allowable fragment size to use.

   host1(config-if)#ppp fragmentation 128

   Note: You can specify the maximum fragment size for a link only when you use the ppp fragmentation command to enable fragmentation on that link. You cannot specify the maximum fragment size for a link when fragmentation is disabled.

4. Enable reassembly on the link interface, and optionally specify the administrative MRRU value to use.

   host1(config-if)#ppp reassembly 1590

   Note: You can specify the administrative MRRU value for a link only when you use the ppp reassembly command to enable reassembly on that link. You cannot specify the administrative MRRU for a link when reassembly is disabled.

5. Exit Interface Configuration mode.

   host1(config-if)#exit

6. Repeat Steps 1 through 5 for each additional link interface on which you want to configure fragmentation and reassembly. For example:

   host1(config)#interface serial 4/0:1/1/1/1/2

   host1(config-if)#encapsulation mlppp

   host1(config-if)#ppp fragmentation 128

   host1(config-if)#ppp reassembly 1590

   host1(config-if)#exit

7. Define the MLPPP bundle.

   host1(config)#interface mlppp group1

8. Add each member link to the bundle.

   host1(config-if)#member-interface serial 4/0:1/1/1/1/1

   host1(config-if)#member-interface serial 4/0:1/1/1/1/2

9. Assign an IP address to the MLPPP bundle.

   host1(config-if)#ip address 10.10.100.1 255.255.255.0
