ASR1000-ESP20 Overview

The Cisco ASR1000-ESP20 forwarding performance will vary depending on features configured. Up to 4 Mpps for the combination of the following commonly-used features: IPv4 forwarding, IP Multicast, ACL, QoS, Reverse Path Forwarding (RPF), load balancing, and Sampled NetFlow.

This ASR1000-ESP20 is similar with the ASR1000-ESP20=. The  ASR1000-ESP20= is a spare one.
