Hello all, I'd like to hear the community's opinion and experience when working with switch or router "clusters". By saying cluster I assume any kind of closely coupled systems, active/active or active/standby, such as VSS, vPC, mLACP.
Also I assume that the cluster members will be physically close to each other and all uplink/downlink devices will be dual homed on both cluster members. Given the above, I wonder if such systems should be equipped with dual RSPs or not. In case of dual RSPs, any RSP failure will trigger the standby RSP and the device will try to maintain forwarding by transferring the execution of processes to the previously standby RSP. In case of single RSP, any RSP failure will trigger the clustering mechanism and ideally the other member of the cluster should take over. Would you prefer a chassis or an RSP failover having in mind the highest possible service availability? Thanks, George _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
