Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010, Configuration Manual

Page: 360 / 774

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
Static MLPPP over ATM 1483 Example
The following example configures MLPPP fragmentation and reassembly for two
member links in an MLPPP bundle over an ATM 1483 subinterface.
host1(config)# interface atm 2/0
host1(config-if)# interface atm 2/0.2
host1(config-subif)# atm pvc 42 0 42 aal5snap
host1(config-subif)# encapsulation mlppp
host1(config-subif)# ppp fragmentation
host1(config-subif)# ppp reassembly 1400
host1(config-subif)# ppp authentication pap chap
host1(config-subif)# exit
host1(config)# interface atm 2/0.3
host1(config-subif)# atm pvc 43 0 43 aal5snap
host1(config-subif)# encapsulation mlppp
host1(config-subif)# ppp fragmentation
host1(config-subif)# ppp reassembly 1600
host1(config-subif)# ppp authentication pap chap
host1(config-subif)# exit
host1(config)# interface mlppp client1
host1(config-if)# member-interface atm 2/0.2
host1(config-if)# member-interface atm 2/0.3
