RCB while a redundnat configuration ships with two RCBs. When two RCBs are installed, one functions
as the master and the second as a backup. If the master RCB is removed, the backup becomes the master
if graceful Routing Engine switchover (GRES) is configured.
MX10016 supports the following Routing Engines:
•
JNP10K-RE1
•
JNP10K-RE1-LT
•
JNP10K-RE1-128G

Routing and Control Board Functions
The Routing and Control Board (RCB) integrates the control plane and Routing Engine functions into a
single management unit. Each RCB provides all the functions needed to manage the operation of the
modular chassis:
•
System control functions such as environmental monitoring
•
Routing Layer 2 and Layer 3 protocols
•
Communication to all components such as line cards, Switch Fabric Boards (SFBs), and power and cooling
•
Transparent clocking
•
Alarm and logging functions
Routing and Control Board Components
Each Routing and Control Board (RCB) consists of the following internal components:
•
CPU—Runs Junos OS to maintain the routing tables and routing protocols.
•
EEPROM—Stores the serial number of the Routing Engine.
•
DRAM—Provides storage for the routing and forwarding tables and for other Routing Engine processes.
