Configuring the JUNOS Software to Run in the IP and Ethernet Services Mode in MX Series Routers

MX Series Ethernet services routers can be configured to run in IP Services mode or Ethernet Services mode. The default IP Services mode provides complete functionality. The Ethernet Services mode only provides support for Layer 2.5 functions.

Operating in Ethernet Services mode restricts certain BGP protocol functions and does not support Layer 3 VPN, unicast RPF, and source and destination class usage (SCU and DCU) functions. In addition, the number of externally configured filter terms are restricted to 64K. The details of Layer 2.5 support for Ethernet Services are shown in Restrictions on JUNOS Features for MX Series Routers.

To configure the network services mode of an MX Series router, include the network-services statement with the appropriate option at the [edit chassis] hierarchy level:

[edit chassis]network-services (ethernet | ip);
  • A router chassis with a 16x10GE MPC with model number MPC-3D-16XGE-SFPP requires that the chassis be configured in the Ethernet network services mode.
  • A router chassis with a 16x10GE MPC with model number MPC-3D-16XGE-SFPP-R-B can be configured in the Ethernet network services mode or the IP network services mode. However, this requires installing the appropriate license to enable the use of the IP network services mode.
  • A router chassis with both 16x10GE MPC models, MPC-3D-16XGE-SFPP and MPC-3D-16XGE-SFPP-R-B must be configured in the Ethernet network services mode.

If DPCs in Ethernet Services mode are up and running, the system cannot be set to IP services mode. You must set any Ethernet mode DPCs offline before switching to IP Services mode.
