TX Matrix Plus RE-C2600 Routing Engine Overview

26
Processing of routing protocol packets—The Routing Engine handles all packets that
concern routing protocols, freeing the Packet Forwarding Engine to handle only packets
that represent Internet traffic.
Software modularity—Because each software process is devoted to a different function
and uses a separate process space, the failure of one process has little or no effect on
the others.
In-depth Internet functionality—Each routing protocol is implemented with a complete
set of Internet features and provides full flexibility for advertising, filtering, and modifying
routes. Routing policies are set according to route parameters (for example, prefix,
prefix lengths, and Border Gateway Protocol [BGP] attributes).
Scalability—The Junos routing tables have been designed to hold all the routes in
current networks with ample capacity for expansion. Additionally, the Junos OS can
efficiently support large numbers of interfaces and virtual circuits.
Management interface—Different levels of system management tools are provided,
including the Junos OS command-line interface (CLI), the Junos XML management
protocol, the craft interface, and SNMP.
Storage and change management—Configuration files, system images, and microcode
can be held and maintained in primary and secondary storage systems, permitting
local or remote upgrades.
Monitoring efficiency and flexibility—The TX Matrix Plus router supports functions such
as alarm handling and packet counting on every port, without degrading
packet-forwarding performance.

RE-C2600 Description

Each RE-C2600 (shown in Figure 11 on page 27) consists of the following components:
CPU—Runs Junos OS to maintain the TX Matrix Plus routing tables and routing
protocols.
DRAM—Provides storage for the routing and forwarding tables and for other Routing
Engine processes.
EEPROM—Stores the serial number of the Routing Engine.
Interfaces for management access—Provide information about Routing Engine status
to the external management devices (console, laptop, or terminal server) connected
to the TXP Routing Engine ports located below the Routing Engine on the TXP-CB.
