Static IPv4 subscribers over statically configured soft-GRE tunnels

This feature is intended for Service Providers using Fixed Wireless LAN (WLAN) to provide network access to subscribers. Service Providers can use this feature to provision static IPv4 subscribers wherein the following conditions are true:

• The IP address of the Customer Premises Equipment (CPE) router is statically configured on both the CPE and the Broadband Network Gateway (BNG).
• The data is transmitted over statically configured soft-GRE tunnels.

Control plane protocols such as PPPoE or DHCP do not run on the CPE to provision the CPE IP address. The soft-GRE tunnel is brought up by the configuration and will stay up as long as the configuration is present on the router. The static subscriber requires the underlying soft-GRE tunnel to be present before it comes up.

The static subscriber can access all BNG services including policers, Class of Service (CoS), accounting and more, based on the configuration.

A static tunnel configuration must be defined under the set services soft-gre gre-group hierarchy with a tunnel name and remote address. These subscribers are associated with statically configured demux1 logical interfaces with IPv4 prefixes, defined under the set system services static-subscribers hierarchy.
