Multilink and Link Services Logical Interface Configuration Overview
You configure multilink and link services interface properties at the logical unit level. Default settings for multilink and link services logical interface properties are described in Default Settings for Multilink and Link Services Logical Interfaces.
For general information about logical unit properties or family inet properties, see the Junos Network Interfaces Configuration Guide. For information about multilink and link services properties you configure at the family inet hierarchy level, see Configuring the Links in a Multilink or Link Services Bundle.
 | Note: On DS0, E1, or T1 interfaces in LSQ bundles, you can configure the bandwidth statement, but the router does not use the bandwidth value if the interfaces are included in an MLPPP or MLFR bundle. The bandwidth is calculated internally according to the time slots, framing, and byte-encoding of the interface. For more information about logical interface properties, see the Junos Network Interfaces Configuration Guide. |
Default Settings for Multilink and Link Services Logical Interfaces
Table 1 lists the default settings for multilink and link services statements, together with the other permitted values or value ranges.
Table 1: Multilink and Link Services Logical Interface Statements
Option | Default Value | Possible Values |
|---|---|---|
DLCI | None | 16 through 1022 |
Drop timeout period | 500 ms for bundles greater than or equal to the T1 bandwidth value and 1500 ms for other bundles. | 0 through 2000 milliseconds |
Encapsulation | For multilink interfaces, multilink-ppp. For link services interfaces, multilink-frame-relay-end-to-end. | multilink-frame-relay-end-to-end, multilink-ppp |
Fragmentation threshold | 0 bytes | 128 through 16,320 bytes (Nx64) |
Interleave fragments | disabled | enabled, disabled |
Minimum links | 1 link | 1 through 8 links |
Maximum received reconstructed unit (MRRU) | 1504 bytes | 1500 through 4500 bytes |
Sequence ID format for MLPPP | 24 bits | 12 or 24 bits |
Sequence ID format for MLFR FRF.15 and FRF.16 | 12 bits | 12 bits |
See Default Settings for Link Services Interfaces for statements that apply to link services physical interfaces only.
