7750 SR Interface Configuration Guide
MC-MLPPP must be configured before links are added to a bundle.
MC-MLPPP and LFI (config>port>multilink-bundle>interleave-fragments) are
mutually exclusive.
MC-MLPPP is not supported when port is configured as network mode.
MC-MLPPP can be enabled on every MLPPP bundle and bundle protection group.
MC-MLPPP is supported only on ASAP MDAs (for example, m4-choc3-as-sfp, m1-
choc12-as-sfp, m4-chds3-as, m12-chds3-as).
Short and long sequence packet formats are supported (both ends must be of the same
type) with static mapping of forwarding classes to MC-MLPPP class (based on the
number of classes negotiated with the far end).
Single fragment size for all classes is supported.
Prefix elision is not supported. The prefix elision (
option advises the peer that, in each of the given classes, the implementation expects to
receive only packets with a certain prefix; this prefix is not to be sent as part of the
information in the fragment(s) of this class.
Fractional DS1/E1 MLPPP links are supported. This is applicable to MLPPP bundles on
ASAP MDAs. Fractional E1 and Fractional DS1 links cannot be combined in the same
bundle.
