Configuring Fragmentation and Reassembly for Static MLPPP
Copyright © 2010, Juniper Networks, Inc.
To configure fragmentation and reassembly on a static MLPPP link interface:
From Global Configuration mode, specify the individual link interface on which you
1.
want to configure fragmentation and reassembly.
host1(config)#interface serial 4/0:1/1/1/1/1
Specify MLPPP as the encapsulation method on the link interface.
2.
host1(config-if)#encapsulation mlppp
Enable fragmentation on the link interface, and optionally specify the maximum
3.
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.
Enable reassembly on the link interface, and optionally specify the administrative
4.
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.
Exit Interface Configuration mode.
5.
host1(config-if)#exit
Repeat Steps 1 through 5 for each additional link interface on which you want to
6.
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
Define the MLPPP bundle.
7.
host1(config)#interface mlppp group1
Add each member link to the bundle.
8.
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
Assign an IP address to the MLPPP bundle.
