routing-services (Enhanced Subscriber Management)
Statement introduced in Junos OS Release 15.1R3 on MX Series routers for enhanced subscriber management.
Statement deprecated in Junos OS Release 18.4R1.
Enable configuration of additional routing protocols required by client connections on dynamically created enhanced subscriber management interfaces.
When clients use only the standard access-internal routes, access routes, and framed routes, you do not need to configure routing services. In other words, the routing service configuration is not required for simple client reachability purposes.
You do not need to configure routing services for Internet Group Management Protocol (IGMP) and the Multicast Listener Discovery (MLD) protocol because these protocols are natively supported on enhanced subscriber management interfaces.
routing-services is supported only for the Layer 2 Tunneling Protocol (L2TP) network server subscribers. Any other access models, otherwise mentioned, for example aggregated inline service interface, Multilink Point-to-Point Protocol (MLPPP) over L2TP network server (LNS) are not supported.
When a dynamic profile containing the routing-services statement is instantiated, the router creates an enhanced subscriber management logical interface, also referred to as a pseudo logical interface, in the form demux0.nnnnnnnnnn (for example, demux0.3221225472). Any associated subscriber routes or routes learned from a routing protocol running on the enhanced subscriber management interface use this pseudo interface as the next-hop interface.
Starting in Junos OS Release 18.4R1, the routing-services statement is deprecated. It is replaced by the routing-service statement. If you upgrade to Junos OS Release 18.4R1 or higher with a configuration that has active subscribers with routing-services enabled, then routing services remain enabled for those subscribers. For all new subscribers after the upgrade, you must use the routing-service statement.
The routing-services statement is not supported for DHCP dynamic profiles. Do not enable it for DHCP dynamic profiles. However, if the routing-services statement is enabled for a dynamic VLAN profile, that VLAN can stack DHCP subscribers.
Configuration of additional routing protocols associated with the client connection is disabled by default on enhanced subscriber management dynamic interfaces when you do not include this statement in the dynamic profile.
