Network Services Mode Overview

You can configure network services modes on MX Series 3D Universal Edge Routers and on T4000 Core Routers with Type 5 FPCs.

• MX Series 3D Universal Edge Routers can be configured to run in IP Network Services mode, Enhanced IP Network Services mode, Ethernet Network Services mode, or Enhanced Ethernet Network Services mode. Each network services mode defines how the chassis recognizes and uses certain modules.

  Note: You can use either Enhanced IP Network Services mode or Enhanced Ethernet Network Services mode to improve the scaling and performance specific to routing filters in a subscriber access network that uses statically configured subscriber interfaces. For more information about using enhanced network services modes with firewall filters, see Firewall Filters and Enhanced Network Services Mode Overview in the Junos OS Subscriber Management, Release 13.1.

• Junos OS Release 12.3 enables improved virtual private LAN service (VPLS) MAC address learning on T4000 routers with Type 5 FPCs by supporting up to 262,143 MAC addresses per VPLS routing instance. In Junos OS releases before Release 12.3, T4000 routers with Type 5 FPCs support only 65,535 MAC addresses per VPLS routing instance

  To improve MAC address learning on T4000 Core Routers with Type 5 FPCs, enable network services mode and then reboot the router. After the router reboots, modify the size of the MAC address table to the new limit—that is, 262,143 addresses.

  The MAC address learning limit for each interface remains the same (that is, 65,535 MAC addresses). You must reboot the router after configuring the enhanced-mode statement. When the T4000 router reboots, only the T4000 Type 5 FPCs are online while the remaining FPCs are offline.

• You must configure a router chassis that has only MPC-3D-16XGE-SFPP modules installed for Ethernet Network Services mode or Enhanced Ethernet Network Services mode.
• You can configure a router chassis with only MPC-3D-16XGE-SFPP-R-B modules installed for any network services mode. However, this configuration requires installing the appropriate license if you want to use IP Network Services mode or Enhanced IP Network Services mode. However, this configuration requires installing the licensed copies of the IP Network Services mode or Enhanced IP Network Services mode. The licenses for these services are paper licenses.
• You must configure a router chassis that has both MPC-3D-16XGE-SFPP and MPC-3D-16XGE-SFPP-R-B modules installed for Ethernet Network Services mode or Enhanced Ethernet Network Services mode.

Note: If Dense Port Concentrators (DPCs) in Ethernet Network Services mode or Enhanced Ethernet Network Services mode are up and running, you cannot configure the system for IP Network Services mode. You must first disable any Ethernet Network Services mode DPCs before switching to IP Network Services mode.

Table 1 explains the different module functions when you configure the MX Series 3D Universal Edge router chassis for different network services modes.

The details of Layer 2.5 support for Ethernet Network Services mode are shown in Restrictions on Junos OS Ethernet Network Services Mode and Enhanced Ethernet Network Services Mode Features for MX Series Routers.
