Other Protocol Suites

In addition to the common protocol suites, JUNOS protocol families sometimes use the following protocol suites:

ccc—Circuit cross-connect (CCC).
mlfr-uni-nni—Multilink Frame Relay (MLFR) FRF.16 user-to-network network-to-network (UNI NNI).
mlfr-end-to-end—Multilink Frame Relay end-to-end.
mlppp—Mulitlink Point-to-Point Protocol.
tcc—Translational cross-connect (TCC).
tnp—Trivial Network Protocol. This Juniper Networks proprietary protocol provides communication between the Routing Engine and the device's packet forwarding components. The JUNOS software automatically configures this protocol family on the device's internal interfaces only.
