494 ! Understanding Redundant Routing Engines
M10i Router Routing Engine Redundancy
The M10i router has redundant Routing Engines. The M10i router has one Routing
Engine in slot
RE0 and another in slot RE1 (see Figure 193). By default, the Routing
Engine in slot
RE0 is the master and the one in slot RE1 is the backup. If one
Routing Engine fails, the other one assumes the routing functions.
The M10i router Routing Engine faceplate has LEDs that indicate redundant Routing
Engine operating status and mastership. (See “Check the M10i Router Routing
Engine LEDs” on page 139.)
