Configuring CFEB Redundancy on the M10i Router

The Compact Forwarding Engine Board (CFEB) on the M10i router provides route lookup, filtering, and switching on incoming data packets, and then directs outbound packets to the appropriate interface for transmission to the network. The CFEB communicates with the Routing Engine using a dedicated 100-Mbps Fast Ethernet link that transfers routing table data from the Routing Engine to the forwarding table in the integrated ASIC. The link is also used to transfer from the CFEB to the Routing Engine routing link-state updates and other packets destined for the router that have been received through the router interfaces.

To configure a CFEB redundancy group, include the following statements at the [edit chassis redundancy] hierarchy level:

slot-number can be 0 or 1.

always defines the CFEB as the sole device.

preferred defines a preferred CFEB.

To manually switch CFEB primary role, issue the request chassis cfeb master switch command. To view CFEB status, issue the show chassis cfeb command.
