The 1G memory option is for use with 3bXLs, to support large FIB tables that get downloaded to the linecard. The RP builds the FIB from the Routing Protocols RIBs, it then downloads the table and when changes occur the changes to the linecard CPU, which keeps a copy of the FIB, and the linecard CPU programs the FIB entries into hardware forwarding table. It also holds the software version of the QoS and Security ACL tables that are programmed into the hardware TCAMs. Ian >TIA, > >Nick Griffin >_______________________________________________ >cisco-nsp mailing list cisco-nsp@puck.nether.net >https://puck.nether.net/mailman/listinfo/cisco-nsp >archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
