Broadband Scalability and Performance IP Sessions Scaling - Intelligent Services Gateway (ISG) Services are not supported - Point-to-Point Protocol over ATM (PPPoA) and Point-to-Point Protocol over Ethernet (PPPoEoA) sessions are not supported - RP2 requires 16 GB DRAM to support 48000 sessions Note If any of the listed restrictions is not met, the router scales to a maximum of 32000 sessions only. • Restrictions on the 64000 session scaling with RP2 and ESP-40G: - ISG services are not supported - PPPoA and PPPoEoA sessions are not supported - Per-session QoS with queuing actions (for example, shaping) is not supported - RP2 requires 16 GB DRAM to support 64000 sessions Note If any of the listed restrictions is not met, the router scales to a maximum of 32000 sessions or 48000 sessions only. • Restrictions on 64000 L2TP tunnel scaling with RP2 and ESP-40G: - ISG services are not supported - Per-session QoS is not supported - RP2 requires 16 GB DRAM - High Availability (SSO) is not supported Note If any of the listed restrictions is not met, the router scales to a maximum of 16000 L2TP tunnels. • The RP2 and ESP10 hardware combination is not supported for broadband. • RP1 with 2GB of DRAM is not recommended for broadband deployment. IP Sessions Scaling The ASR 1000 Series Routers can be deployed as an IP session aggregator. The maximum number of IP sessions that can be supported depends on the hardware combination. Table 20 lists the hardware combination and the maximum number of IP sessions that are supported. The session limits apply to all variety of IP session initiators: DHCP, unclassified Mac address, unclassified IP, and RADIUS proxy.
