Overview of a Routing Matrix with a TXP-Mixed-LCC-3D Configuration
A routing matrix with the TXP-Mixed-LCC-3D configuration consists of three types of chassis: a Juniper Networks TX Matrix Plus router and a combination of Juniper Networks T1600 Core Routers and Juniper Networks T4000 Core Routers.
- TX Matrix Plus router—A routing matrix contains only one Juniper Networks TX Matrix Plus router. A TX Matrix Plus router in a routing matrix is also referred to as the switch-fabric chassis (SFC). In the Junos OS CLI, sfc 0 is used to refer to the TX Matrix Plus router. For information about installing and connecting to a TX Matrix Plus router, see the TX Matrix Plus Router Hardware Guide .
- T1600 and T4000 routers—In the mixed LCC configuration,
a routing matrix can comprise:
- Six T1600 routers and one T4000 router
- Four T1600 routers and two T4000 routers
- Two T1600 routers and three T4000 routers
To enable the TXP-Mixed-LCC-3D configuration in the Junos OS CLI, you must configure the LCC mode on the SFC. To configure the LCC mode, include the set lcc-mode lcc lcc-number mode (empty | t1600 | t4000) statement at the [edit chassis] hierarchy level. By default, the LCC mode is set to t1600.
To view the configured LCC mode information, use the show chassis lcc-mode operational mode command.
