Configuring Fragmentation and Reassembly for Dynamic MLPPP
To configure fragmentation and reassembly for dynamic MLPPP, you must create a profile that includes commands to define the link and bundle attributes, just as you do for a static MLPPP configuration.
For more information, see:
- Dynamic Interface Configuration Using a Profile
- LAC Configuration Prerequisites
- LNS Configuration Prerequisites
To define a profile that configures MLPPP fragmentation and reassembly for a dynamic MLPPP interface:
- From Global Configuration mode, create a profile by assigning
it a name, and access Profile Configuration mode.host1(config)#profile dynmlppp1 host1(config-profile)#
- Enable the creation of dynamic MLPPP interfaces.host1(config-profile)#ppp multilink enable
- Enable fragmentation on the link interface, and optionally
specify the maximum allowable fragment size to use.host1(config-profile)#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 MRRU value to use.host1(config-profile)#ppp reassembly 1800
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.
- (Optional) Specify a virtual router to which dynamic IP
interfaces created with this profile will be assigned.host1(config-profile)#ip virtual-router boston
- (Optional) Specify an IP loopback interface with which
dynamic IP interfaces created with this profile will be associated.host1(config-profile)#ip unnumbered loopback 0
- (Optional) Set other PPP characteristics as needed by using the ppp commands. For more information about the ppp commands, see JunosE Command Reference Guide.
