M7i Internet Router Overview
The M7i Internet router provides security and performance in small to medium
Points of Presence (PoPs), as well as a carrier-class customer premise equipment
(CPE) solution for managed services and campus border router applications.
(See Figure 2.)

The M7i router includes the Compact Forwarding Engine Board (CFEB) which
provides route lookup, filtering, and switching on incoming data packets, then
directs outbound packets to the appropriate interface for transmission to the
network. It can process 16 million packets per second (Mpps). The CFEB
communicates with the Routing Engine using a dedicated 100-Mbps link that
transfers routing table data from the Routing Engine to the forwarding table. The
link is also used to transfer routing link-state updates and other packets destined for
the router from the CFEB to the Routing Engine.
A built-in tunnel interface encapsulates arbitrary packets inside a transport
protocol, providing a private, secure path through an otherwise public network. The
built-in tunnel interface on the CFEB is configured the same way as a PIC. For
information about configuring the built-in tunnel interface, see the JUNOS Services
Interfaces Configuration Guide.
The Adaptive Services PIC-Integrated (ASP-I) is an optional component on the CFEB
which performs one or more services on traffic—Stateful firewall, Network Address
Translation (NAT) or intrusion detection services (IDS)—before it reaches its
destination.
