    ppp mru

    Syntax

    ppp mru mruSize

    no ppp mru

    Release Information

    Command introduced before JunosE Release 7.1.0.

    Description

    Sets the maximum allowable size in bytes of the maximum receive unit for PPP or MLPPP interfaces. If you issue the command in the context of an encapsulated PPP or MLPPP interface, it affects only that interface. If you issue the command in the context of an MLPPP bundle, it affects all member links within that bundle.

    If the value configured for the PPP MRU is greater than the value of the lower-layer MRU minus the PPP header length, the router logs a warning message and uses the lesser of the configured MRU value or the lower-layer MRU value minus the PPP header length to negotiate the local MRU. If the value configured for the PPP MRU conflicts with a similar value configured for another protocol, such as the MTU value for PPPoE, the router uses the lesser of the two values.

    The no version restores the default value, the lower-layer MRU minus the PPP header length, which varies according to module type.

    Note: We recommend you coordinate this value with the network administrator on the other end of the line.

    Options

    • mruSize—Maximum allowable size of the MRU; number of bytes in the range 64–65535

    Mode

    Interface Configuration, Profile Configuration, Subinterface Configuration
