Protocols and Applications Supported by the MX240, MX480, MX960 MPC3E

contains the first Junos OS Release support for protocols and

applications on the MX Series MPC3E. The protocols and applications support feature
parity with Junos OS Release 10.4. A dash indicates that the protocol or application is
not supported.
